Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add build-many-glibcs.py bot-cycle action.
This patch continues the process of setting up build-many-glibcs.py to
run as a bot monitoring for and reporting on build issues by adding a
bot-cycle action to the script. When this action is used, it will run
the checkout action (re-execing itself if it was changed by that
action), then rebuild whichever of host-libraries, compilers, glibcs
should be rebuilt based on changed versions, time elapsed and state of
previous builds. Email is sent with the results of the build (for
each build action done).
The rebuild logic is: if previous build time or versions aren't
recorded, rebuild that component. If the script has changed, rebuild
everything. If any relevant component version has changed, rebuild,
except for not rebuilding compilers if the time indicated in the bot
configuration has not passed since the last build of the compilers.
If one piece is rebuilt then rebuild subsequent pieces as well.
Using bot-cycle requires a configuration file bot-config.json in the
toplevel directory used by build-many-glibcs.py. It might contain
e.g.
{
"compilers-rebuild-delay": 604800,
"email-from": "Example Name <user@example.org>",
"email-server": "localhost",
"email-subject": "GCC 6 %(action)s %(build-time)s build results",
"email-to": "libc-testresults@sourceware.org"
}
My next intended step is adding a further action "bot" which loops
running bot-cycle then sleeping for an amount of time given in
bot-config.json. Then I'll set up a bot using that action (building
with GCC 6 branch; a bot using GCC mainline may wait until the SH
out-of-memory issues
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78460> are fixed; I
expect the bot to mail to me until it seems ready to switch to mailing

configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add build-many-glibcs.py bot-cycle action.
This patch continues the process of setting up build-many-glibcs.py to
run as a bot monitoring for and reporting on build issues by adding a
bot-cycle action to the script. When this action is used, it will run
the checkout action (re-execing itself if it was changed by that
action), then rebuild whichever of host-libraries, compilers, glibcs
should be rebuilt based on changed versions, time elapsed and state of
previous builds. Email is sent with the results of the build (for
each build action done).
The rebuild logic is: if previous build time or versions aren't
recorded, rebuild that component. If the script has changed, rebuild
everything. If any relevant component version has changed, rebuild,
except for not rebuilding compilers if the time indicated in the bot
configuration has not passed since the last build of the compilers.
If one piece is rebuilt then rebuild subsequent pieces as well.
Using bot-cycle requires a configuration file bot-config.json in the
toplevel directory used by build-many-glibcs.py. It might contain
e.g.
{
"compilers-rebuild-delay": 604800,
"email-from": "Example Name <user@example.org>",
"email-server": "localhost",
"email-subject": "GCC 6 %(action)s %(build-time)s build results",
"email-to": "libc-testresults@sourceware.org"
}
My next intended step is adding a further action "bot" which loops
running bot-cycle then sleeping for an amount of time given in
bot-config.json. Then I'll set up a bot using that action (building
with GCC 6 branch; a bot using GCC mainline may wait until the SH
out-of-memory issues
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78460> are fixed; I
expect the bot to mail to me until it seems ready to switch to mailing
to gcc-testresults).
* scripts/build-many-glibcs.py: Add bot-cycle to usage message.
Import email.mime.text, email.utils and smtplib modules.
(Context.__init__): Initialize self.bot_config_json.
(Context.run_builds): Handle bot-cycle action.

Add build-many-glibcs.py support for building more GCC libraries.
Every so often we get libsanitizer or libgo builds breaking with new
glibc because of some change in the glibc headers.
glibc's build-many-glibcs.py deliberately disables libsanitizer and
GCC languages other than C and C++ because the point is to test glibc
and find glibc problems (including problems shown up by new compiler
warnings in new GCC), not to test libsanitizer or libgo; if the
compiler build fails because of libsanitizer or libgo failing to
build, that could hide the existence of new problems in glibc.
However, it seems reasonable to have a non-default mode where
build-many-glibcs.py does build those additional pieces, which this
patch adds.
Note that I do not intend to run a build-many-glibcs.py bot with this
new option. If people concerned with libsanitizer, libgo or other
potentially affected GCC libraries wish to find out about such
problems more quickly, they may wish to run such a bot or bots (and to
monitor the results and fix issues found - obviously there will be
some overlap with issues found by my bots not using that option).
Note also that building a non-native Ada compiler requires a
sufficiently recent native (or build-x-host, in general) Ada compiler
to be used, possibly more or less the same version as being built.
That needs to be in the PATH when build-many-glibcs.py --full-gcc is
run; the script does not deal with setting up such a compiler (or any
of the other host tools needed for building GCC and glibc, beyond the
GMP / MPFR / MPC libraries), but perhaps it should, to avoid the need
to keep updating such a compiler manually when running a bot.
Tested by running build-many-glibcs.py with the new option, with
mainline GCC. There are build failures for various configurations,
which may be of interest to Go / Ada people even if you're not
interested in running such a bot:
* mips64 / mips64el (all configuration): ICE building libstdc++, as
seen without using the new option
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87156>.
* aarch64_be: error building libgo (little-endian aarch64 works fine):
version.go:67:13: error: expected ';' or ')' or newline
67 | BigEndian =
| ^
version.go:67:3: error: reference to undefined name 'BigEndian'
67 | BigEndian =
| ^
* arm (all configurations): error building libgo:
/scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:29:5: error: reference to undefined name 'randomTrap'
29 | if randomTrap == 0 {
| ^
/scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:38:34: error: reference to undefined name 'randomTrap'
38 | r1, _, errno := syscall.Syscall(randomTrap,
| ^
What's happening there is, I think, that the arm*b*-*-* case in
libgo/configure.ac is wrongly matching arm-glibc-linux-gnueabi with
the 'b' in the vendor part, and then something else is failing to
handle GOARCH=armbe. Given that you can have configurations with
multilibs of both endiannesses, endianness should always be detected
by configure.ac, for all architectures, using a compile test of
whether __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__, not based on textual
matches to the host (= target at top-level) triplet.
* armeb (all configurations): error building libada (for some reason
the Arm libada configuration seems to do different things for EH for
big-endian, which makes no sense to me and doesn't actually work):
a-exexpr.adb:87:06: "System.Exceptions.Machine" is not a predefined library unit
a-exexpr.adb:87:06: "Ada.Exceptions (body)" depends on "Ada.Exceptions.Exception_Propagation (body)"
a-exexpr.adb:87:06: "Ada.Exceptions.Exception_Propagation (body)" depends on "System.Exceptions.Machine (spec)"
* hppa: error building libgo (same error as for aarch64_be).
* ia64: ICE building libgo. I've filed
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87281> for this.
* m68k: ICE in the Go front end building libgo
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84948>.
* microblaze, microblazeel, nios2, sh3, sh3eb: build failure in libada
for lack of a libada port to those systems (I'm not sure sh3 would
actually need anything different from sh4):
a-cbdlli.ads:38:14: violation of restriction "No_Finalization" at system.ads:47
* i686-gnu: build failure in libada, might be fixed by the patch
attached to <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81103>
(not tested):
terminals.c:1115:13: fatal error: termio.h: No such file or directory
* scripts/build-many-glibcs.py (Context.__init__): Add full_gcc
argument.
(Config.build_gcc): Use --disable-libsanitizer for first GCC
build, but not for second build if --full-gcc. Use
--enable-languages=all for second build if --full-gcc.

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add build-many-glibcs.py bot-cycle action.
This patch continues the process of setting up build-many-glibcs.py to
run as a bot monitoring for and reporting on build issues by adding a
bot-cycle action to the script. When this action is used, it will run
the checkout action (re-execing itself if it was changed by that
action), then rebuild whichever of host-libraries, compilers, glibcs
should be rebuilt based on changed versions, time elapsed and state of
previous builds. Email is sent with the results of the build (for
each build action done).
The rebuild logic is: if previous build time or versions aren't
recorded, rebuild that component. If the script has changed, rebuild
everything. If any relevant component version has changed, rebuild,
except for not rebuilding compilers if the time indicated in the bot
configuration has not passed since the last build of the compilers.
If one piece is rebuilt then rebuild subsequent pieces as well.
Using bot-cycle requires a configuration file bot-config.json in the
toplevel directory used by build-many-glibcs.py. It might contain
e.g.
{
"compilers-rebuild-delay": 604800,
"email-from": "Example Name <user@example.org>",
"email-server": "localhost",
"email-subject": "GCC 6 %(action)s %(build-time)s build results",
"email-to": "libc-testresults@sourceware.org"
}
My next intended step is adding a further action "bot" which loops
running bot-cycle then sleeping for an amount of time given in
bot-config.json. Then I'll set up a bot using that action (building
with GCC 6 branch; a bot using GCC mainline may wait until the SH
out-of-memory issues
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78460> are fixed; I
expect the bot to mail to me until it seems ready to switch to mailing
to gcc-testresults).
* scripts/build-many-glibcs.py: Add bot-cycle to usage message.
Import email.mime.text, email.utils and smtplib modules.
(Context.__init__): Initialize self.bot_config_json.
(Context.run_builds): Handle bot-cycle action.

compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Remove --with-fp / --without-fp.
There is a configure option --without-fp that specifies that nofpu
sysdeps directories should be used instead of fpu directories.
For most glibc configurations, this option is of no use: either there
is no valid nofpu variant of that configuration, or there are no fpu
or nofpu sysdeps directories for that processor and so the option does
nothing. For a few configurations, if you are using a soft-float
compiler this option is required, and failing to use it generally
results in compilation errors from inline asm using unavailable
floating-point instructions.
We're moving away from --with-cpu to configuring glibc based on how
the compiler generates code, and it is natural to do so for
--without-fp as well; in most cases the soft-float and hard-float ABIs
are incompatible so you have no hope of building a working glibc with
an inappropriately configured compiler or libgcc.
This patch eliminates --without-fp, replacing it entirely by automatic
configuration based on the compiler. Configurations for which this is
relevant (coldfire / mips / powerpc32 / sh) define a variable
with_fp_cond in their preconfigure fragments (under the same
conditions under which those fragments do anything); this is a
preprocessor conditional which the toplevel configure script then uses
in a test to determine which sysdeps directories to use.
The config.make with-fp variable remains. It's used only by powerpc
(sysdeps/powerpc/powerpc32/Makefile) to add -mhard-float to various
flags variables. For powerpc, -mcpu= options can imply use of
soft-float. That could be an issue if you want to build for
e.g. 476fp, but are using --with-cpu=476 because there isn't a 476fp
sysdeps directory. If in future we eliminate --with-cpu and replace
it entirely by testing the compiler, it would be natural at that point
to eliminate that code as well (as the user should then just use a
compiler defaulting to 476fp and the 476 sysdeps directory would be
used automatically).
Tested for x86_64, and tested with build-many-glibcs.py that installed
shared libraries are unchanged by this patch.

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Remove --with-fp / --without-fp.
There is a configure option --without-fp that specifies that nofpu
sysdeps directories should be used instead of fpu directories.
For most glibc configurations, this option is of no use: either there
is no valid nofpu variant of that configuration, or there are no fpu
or nofpu sysdeps directories for that processor and so the option does
nothing. For a few configurations, if you are using a soft-float
compiler this option is required, and failing to use it generally
results in compilation errors from inline asm using unavailable
floating-point instructions.
We're moving away from --with-cpu to configuring glibc based on how
the compiler generates code, and it is natural to do so for
--without-fp as well; in most cases the soft-float and hard-float ABIs
are incompatible so you have no hope of building a working glibc with
an inappropriately configured compiler or libgcc.
This patch eliminates --without-fp, replacing it entirely by automatic
configuration based on the compiler. Configurations for which this is
relevant (coldfire / mips / powerpc32 / sh) define a variable
with_fp_cond in their preconfigure fragments (under the same
conditions under which those fragments do anything); this is a
preprocessor conditional which the toplevel configure script then uses
in a test to determine which sysdeps directories to use.
The config.make with-fp variable remains. It's used only by powerpc
(sysdeps/powerpc/powerpc32/Makefile) to add -mhard-float to various
flags variables. For powerpc, -mcpu= options can imply use of
soft-float. That could be an issue if you want to build for
e.g. 476fp, but are using --with-cpu=476 because there isn't a 476fp
sysdeps directory. If in future we eliminate --with-cpu and replace
it entirely by testing the compiler, it would be natural at that point
to eliminate that code as well (as the user should then just use a
compiler defaulting to 476fp and the 476 sysdeps directory would be
used automatically).
Tested for x86_64, and tested with build-many-glibcs.py that installed
shared libraries are unchanged by this patch.

This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Remove --with-fp / --without-fp.
There is a configure option --without-fp that specifies that nofpu
sysdeps directories should be used instead of fpu directories.
For most glibc configurations, this option is of no use: either there
is no valid nofpu variant of that configuration, or there are no fpu
or nofpu sysdeps directories for that processor and so the option does
nothing. For a few configurations, if you are using a soft-float
compiler this option is required, and failing to use it generally
results in compilation errors from inline asm using unavailable
floating-point instructions.
We're moving away from --with-cpu to configuring glibc based on how
the compiler generates code, and it is natural to do so for
--without-fp as well; in most cases the soft-float and hard-float ABIs
are incompatible so you have no hope of building a working glibc with
an inappropriately configured compiler or libgcc.
This patch eliminates --without-fp, replacing it entirely by automatic
configuration based on the compiler. Configurations for which this is
relevant (coldfire / mips / powerpc32 / sh) define a variable
with_fp_cond in their preconfigure fragments (under the same
conditions under which those fragments do anything); this is a
preprocessor conditional which the toplevel configure script then uses
in a test to determine which sysdeps directories to use.
The config.make with-fp variable remains. It's used only by powerpc
(sysdeps/powerpc/powerpc32/Makefile) to add -mhard-float to various
flags variables. For powerpc, -mcpu= options can imply use of
soft-float. That could be an issue if you want to build for
e.g. 476fp, but are using --with-cpu=476 because there isn't a 476fp
sysdeps directory. If in future we eliminate --with-cpu and replace
it entirely by testing the compiler, it would be natural at that point
to eliminate that code as well (as the user should then just use a
compiler defaulting to 476fp and the 476 sysdeps directory would be
used automatically).
Tested for x86_64, and tested with build-many-glibcs.py that installed
shared libraries are unchanged by this patch.

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Remove --with-fp / --without-fp.
There is a configure option --without-fp that specifies that nofpu
sysdeps directories should be used instead of fpu directories.
For most glibc configurations, this option is of no use: either there
is no valid nofpu variant of that configuration, or there are no fpu
or nofpu sysdeps directories for that processor and so the option does
nothing. For a few configurations, if you are using a soft-float
compiler this option is required, and failing to use it generally
results in compilation errors from inline asm using unavailable
floating-point instructions.
We're moving away from --with-cpu to configuring glibc based on how
the compiler generates code, and it is natural to do so for
--without-fp as well; in most cases the soft-float and hard-float ABIs
are incompatible so you have no hope of building a working glibc with
an inappropriately configured compiler or libgcc.
This patch eliminates --without-fp, replacing it entirely by automatic
configuration based on the compiler. Configurations for which this is
relevant (coldfire / mips / powerpc32 / sh) define a variable
with_fp_cond in their preconfigure fragments (under the same
conditions under which those fragments do anything); this is a
preprocessor conditional which the toplevel configure script then uses
in a test to determine which sysdeps directories to use.
The config.make with-fp variable remains. It's used only by powerpc
(sysdeps/powerpc/powerpc32/Makefile) to add -mhard-float to various
flags variables. For powerpc, -mcpu= options can imply use of
soft-float. That could be an issue if you want to build for
e.g. 476fp, but are using --with-cpu=476 because there isn't a 476fp
sysdeps directory. If in future we eliminate --with-cpu and replace
it entirely by testing the compiler, it would be natural at that point
to eliminate that code as well (as the user should then just use a
compiler defaulting to 476fp and the 476 sysdeps directory would be
used automatically).
Tested for x86_64, and tested with build-many-glibcs.py that installed
shared libraries are unchanged by this patch.

Remove --with-fp / --without-fp.
There is a configure option --without-fp that specifies that nofpu
sysdeps directories should be used instead of fpu directories.
For most glibc configurations, this option is of no use: either there
is no valid nofpu variant of that configuration, or there are no fpu
or nofpu sysdeps directories for that processor and so the option does
nothing. For a few configurations, if you are using a soft-float
compiler this option is required, and failing to use it generally
results in compilation errors from inline asm using unavailable
floating-point instructions.
We're moving away from --with-cpu to configuring glibc based on how
the compiler generates code, and it is natural to do so for
--without-fp as well; in most cases the soft-float and hard-float ABIs
are incompatible so you have no hope of building a working glibc with
an inappropriately configured compiler or libgcc.
This patch eliminates --without-fp, replacing it entirely by automatic
configuration based on the compiler. Configurations for which this is
relevant (coldfire / mips / powerpc32 / sh) define a variable
with_fp_cond in their preconfigure fragments (under the same
conditions under which those fragments do anything); this is a
preprocessor conditional which the toplevel configure script then uses
in a test to determine which sysdeps directories to use.
The config.make with-fp variable remains. It's used only by powerpc
(sysdeps/powerpc/powerpc32/Makefile) to add -mhard-float to various
flags variables. For powerpc, -mcpu= options can imply use of
soft-float. That could be an issue if you want to build for
e.g. 476fp, but are using --with-cpu=476 because there isn't a 476fp
sysdeps directory. If in future we eliminate --with-cpu and replace
it entirely by testing the compiler, it would be natural at that point
to eliminate that code as well (as the user should then just use a
compiler defaulting to 476fp and the 476 sysdeps directory would be
used automatically).
Tested for x86_64, and tested with build-many-glibcs.py that installed
shared libraries are unchanged by this patch.
* configure.ac (--with-fp): Remove configure option.
(with_fp_cond): New variable.
(libc_cv_with_fp): New configure test. Use this variable instead
of with_fp.
* configure: Regenerated.
* config.make.in (with-fp): Use @libc_cv_with_fp@.
* manual/install.texi (Configuring and compiling): Remove
--without-fp.
* INSTALL: Regenerated.
* sysdeps/m68k/preconfigure (with_fp_cond): Define for ColdFire.
* sysdeps/mips/preconfigure (with_fp_cond): Define.
* sysdeps/powerpc/preconfigure (with_fp_cond): Define for 32-bit.
* sysdeps/sh/preconfigure (with_fp_cond): Define.

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing

Remove --with-fp / --without-fp.
There is a configure option --without-fp that specifies that nofpu
sysdeps directories should be used instead of fpu directories.
For most glibc configurations, this option is of no use: either there
is no valid nofpu variant of that configuration, or there are no fpu
or nofpu sysdeps directories for that processor and so the option does
nothing. For a few configurations, if you are using a soft-float
compiler this option is required, and failing to use it generally
results in compilation errors from inline asm using unavailable
floating-point instructions.
We're moving away from --with-cpu to configuring glibc based on how
the compiler generates code, and it is natural to do so for
--without-fp as well; in most cases the soft-float and hard-float ABIs
are incompatible so you have no hope of building a working glibc with
an inappropriately configured compiler or libgcc.
This patch eliminates --without-fp, replacing it entirely by automatic
configuration based on the compiler. Configurations for which this is
relevant (coldfire / mips / powerpc32 / sh) define a variable
with_fp_cond in their preconfigure fragments (under the same
conditions under which those fragments do anything); this is a
preprocessor conditional which the toplevel configure script then uses
in a test to determine which sysdeps directories to use.
The config.make with-fp variable remains. It's used only by powerpc
(sysdeps/powerpc/powerpc32/Makefile) to add -mhard-float to various
flags variables. For powerpc, -mcpu= options can imply use of
soft-float. That could be an issue if you want to build for
e.g. 476fp, but are using --with-cpu=476 because there isn't a 476fp
sysdeps directory. If in future we eliminate --with-cpu and replace
it entirely by testing the compiler, it would be natural at that point
to eliminate that code as well (as the user should then just use a
compiler defaulting to 476fp and the 476 sysdeps directory would be
used automatically).
Tested for x86_64, and tested with build-many-glibcs.py that installed
shared libraries are unchanged by this patch.

mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In

components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible

--keep=none).

Add build-many-glibcs.py bot-cycle action.
This patch continues the process of setting up build-many-glibcs.py to
run as a bot monitoring for and reporting on build issues by adding a
bot-cycle action to the script. When this action is used, it will run
the checkout action (re-execing itself if it was changed by that
action), then rebuild whichever of host-libraries, compilers, glibcs
should be rebuilt based on changed versions, time elapsed and state of
previous builds. Email is sent with the results of the build (for
each build action done).
The rebuild logic is: if previous build time or versions aren't
recorded, rebuild that component. If the script has changed, rebuild
everything. If any relevant component version has changed, rebuild,
except for not rebuilding compilers if the time indicated in the bot
configuration has not passed since the last build of the compilers.
If one piece is rebuilt then rebuild subsequent pieces as well.
Using bot-cycle requires a configuration file bot-config.json in the
toplevel directory used by build-many-glibcs.py. It might contain
e.g.
{
"compilers-rebuild-delay": 604800,
"email-from": "Example Name <user@example.org>",
"email-server": "localhost",
"email-subject": "GCC 6 %(action)s %(build-time)s build results",
"email-to": "libc-testresults@sourceware.org"
}
My next intended step is adding a further action "bot" which loops
running bot-cycle then sleeping for an amount of time given in
bot-config.json. Then I'll set up a bot using that action (building
with GCC 6 branch; a bot using GCC mainline may wait until the SH
out-of-memory issues
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78460> are fixed; I
expect the bot to mail to me until it seems ready to switch to mailing
to gcc-testresults).

Import email.mime.text, email.utils and smtplib modules.

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all

where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed

Add build-many-glibcs.py support for building more GCC libraries.
Every so often we get libsanitizer or libgo builds breaking with new
glibc because of some change in the glibc headers.
glibc's build-many-glibcs.py deliberately disables libsanitizer and
GCC languages other than C and C++ because the point is to test glibc
and find glibc problems (including problems shown up by new compiler
warnings in new GCC), not to test libsanitizer or libgo; if the
compiler build fails because of libsanitizer or libgo failing to
build, that could hide the existence of new problems in glibc.
However, it seems reasonable to have a non-default mode where
build-many-glibcs.py does build those additional pieces, which this
patch adds.
Note that I do not intend to run a build-many-glibcs.py bot with this
new option. If people concerned with libsanitizer, libgo or other
potentially affected GCC libraries wish to find out about such
problems more quickly, they may wish to run such a bot or bots (and to
monitor the results and fix issues found - obviously there will be
some overlap with issues found by my bots not using that option).
Note also that building a non-native Ada compiler requires a
sufficiently recent native (or build-x-host, in general) Ada compiler
to be used, possibly more or less the same version as being built.
That needs to be in the PATH when build-many-glibcs.py --full-gcc is
run; the script does not deal with setting up such a compiler (or any
of the other host tools needed for building GCC and glibc, beyond the
GMP / MPFR / MPC libraries), but perhaps it should, to avoid the need
to keep updating such a compiler manually when running a bot.
Tested by running build-many-glibcs.py with the new option, with
mainline GCC. There are build failures for various configurations,
which may be of interest to Go / Ada people even if you're not
interested in running such a bot:
* mips64 / mips64el (all configuration): ICE building libstdc++, as
seen without using the new option
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87156>.
* aarch64_be: error building libgo (little-endian aarch64 works fine):
version.go:67:13: error: expected ';' or ')' or newline
67 | BigEndian =

What's happening there is, I think, that the arm*b*-*-* case in
libgo/configure.ac is wrongly matching arm-glibc-linux-gnueabi with
the 'b' in the vendor part, and then something else is failing to
handle GOARCH=armbe. Given that you can have configurations with
multilibs of both endiannesses, endianness should always be detected
by configure.ac, for all architectures, using a compile test of
whether __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__, not based on textual
matches to the host (= target at top-level) triplet.

the Arm libada configuration seems to do different things for EH for

Add build-many-glibcs.py bot-cycle action.
This patch continues the process of setting up build-many-glibcs.py to
run as a bot monitoring for and reporting on build issues by adding a
bot-cycle action to the script. When this action is used, it will run
the checkout action (re-execing itself if it was changed by that
action), then rebuild whichever of host-libraries, compilers, glibcs
should be rebuilt based on changed versions, time elapsed and state of
previous builds. Email is sent with the results of the build (for
each build action done).
The rebuild logic is: if previous build time or versions aren't
recorded, rebuild that component. If the script has changed, rebuild
everything. If any relevant component version has changed, rebuild,
except for not rebuilding compilers if the time indicated in the bot
configuration has not passed since the last build of the compilers.
If one piece is rebuilt then rebuild subsequent pieces as well.
Using bot-cycle requires a configuration file bot-config.json in the
toplevel directory used by build-many-glibcs.py. It might contain
e.g.
{
"compilers-rebuild-delay": 604800,
"email-from": "Example Name <user@example.org>",
"email-server": "localhost",
"email-subject": "GCC 6 %(action)s %(build-time)s build results",
"email-to": "libc-testresults@sourceware.org"
}
My next intended step is adding a further action "bot" which loops
running bot-cycle then sleeping for an amount of time given in
bot-config.json. Then I'll set up a bot using that action (building
with GCC 6 branch; a bot using GCC mainline may wait until the SH
out-of-memory issues
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78460> are fixed; I
expect the bot to mail to me until it seems ready to switch to mailing
to gcc-testresults).

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add build-many-glibcs.py support for building more GCC libraries.
Every so often we get libsanitizer or libgo builds breaking with new
glibc because of some change in the glibc headers.
glibc's build-many-glibcs.py deliberately disables libsanitizer and
GCC languages other than C and C++ because the point is to test glibc
and find glibc problems (including problems shown up by new compiler
warnings in new GCC), not to test libsanitizer or libgo; if the
compiler build fails because of libsanitizer or libgo failing to
build, that could hide the existence of new problems in glibc.
However, it seems reasonable to have a non-default mode where
build-many-glibcs.py does build those additional pieces, which this
patch adds.
Note that I do not intend to run a build-many-glibcs.py bot with this
new option. If people concerned with libsanitizer, libgo or other
potentially affected GCC libraries wish to find out about such
problems more quickly, they may wish to run such a bot or bots (and to
monitor the results and fix issues found - obviously there will be
some overlap with issues found by my bots not using that option).
Note also that building a non-native Ada compiler requires a
sufficiently recent native (or build-x-host, in general) Ada compiler
to be used, possibly more or less the same version as being built.
That needs to be in the PATH when build-many-glibcs.py --full-gcc is
run; the script does not deal with setting up such a compiler (or any
of the other host tools needed for building GCC and glibc, beyond the
GMP / MPFR / MPC libraries), but perhaps it should, to avoid the need
to keep updating such a compiler manually when running a bot.
Tested by running build-many-glibcs.py with the new option, with
mainline GCC. There are build failures for various configurations,
which may be of interest to Go / Ada people even if you're not
interested in running such a bot:
* mips64 / mips64el (all configuration): ICE building libstdc++, as
seen without using the new option
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87156>.
* aarch64_be: error building libgo (little-endian aarch64 works fine):
version.go:67:13: error: expected ';' or ')' or newline
67 | BigEndian =
| ^
version.go:67:3: error: reference to undefined name 'BigEndian'
67 | BigEndian =

* arm (all configurations): error building libgo:
/scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:29:5: error: reference to undefined name 'randomTrap'
29 | if randomTrap == 0 {
| ^
/scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:38:34: error: reference to undefined name 'randomTrap'
38 | r1, _, errno := syscall.Syscall(randomTrap,
| ^
What's happening there is, I think, that the arm*b*-*-* case in
libgo/configure.ac is wrongly matching arm-glibc-linux-gnueabi with
the 'b' in the vendor part, and then something else is failing to
handle GOARCH=armbe. Given that you can have configurations with
multilibs of both endiannesses, endianness should always be detected
by configure.ac, for all architectures, using a compile test of
whether __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__, not based on textual
matches to the host (= target at top-level) triplet.
* armeb (all configurations): error building libada (for some reason
the Arm libada configuration seems to do different things for EH for
big-endian, which makes no sense to me and doesn't actually work):
a-exexpr.adb:87:06: "System.Exceptions.Machine" is not a predefined library unit
a-exexpr.adb:87:06: "Ada.Exceptions (body)" depends on "Ada.Exceptions.Exception_Propagation (body)"

* hppa: error building libgo (same error as for aarch64_be).
* ia64: ICE building libgo. I've filed
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87281> for this.
* m68k: ICE in the Go front end building libgo

* microblaze, microblazeel, nios2, sh3, sh3eb: build failure in libada

actually need anything different from sh4):

* i686-gnu: build failure in libada, might be fixed by the patch
attached to <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81103>
(not tested):

argument.

build, but not for second build if --full-gcc. Use

<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,

build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers

the compilers. compilers can be run once and then used many times for

Add build-many-glibcs.py support for building more GCC libraries.
Every so often we get libsanitizer or libgo builds breaking with new
glibc because of some change in the glibc headers.
glibc's build-many-glibcs.py deliberately disables libsanitizer and
GCC languages other than C and C++ because the point is to test glibc
and find glibc problems (including problems shown up by new compiler
warnings in new GCC), not to test libsanitizer or libgo; if the
compiler build fails because of libsanitizer or libgo failing to
build, that could hide the existence of new problems in glibc.
However, it seems reasonable to have a non-default mode where
build-many-glibcs.py does build those additional pieces, which this
patch adds.
Note that I do not intend to run a build-many-glibcs.py bot with this
new option. If people concerned with libsanitizer, libgo or other
potentially affected GCC libraries wish to find out about such
problems more quickly, they may wish to run such a bot or bots (and to
monitor the results and fix issues found - obviously there will be
some overlap with issues found by my bots not using that option).
Note also that building a non-native Ada compiler requires a
sufficiently recent native (or build-x-host, in general) Ada compiler
to be used, possibly more or less the same version as being built.
That needs to be in the PATH when build-many-glibcs.py --full-gcc is
run; the script does not deal with setting up such a compiler (or any
of the other host tools needed for building GCC and glibc, beyond the
GMP / MPFR / MPC libraries), but perhaps it should, to avoid the need
to keep updating such a compiler manually when running a bot.
Tested by running build-many-glibcs.py with the new option, with
mainline GCC. There are build failures for various configurations,
which may be of interest to Go / Ada people even if you're not
interested in running such a bot:
* mips64 / mips64el (all configuration): ICE building libstdc++, as
seen without using the new option
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87156>.
* aarch64_be: error building libgo (little-endian aarch64 works fine):
version.go:67:13: error: expected ';' or ')' or newline
67 | BigEndian =
| ^
version.go:67:3: error: reference to undefined name 'BigEndian'
67 | BigEndian =
| ^
* arm (all configurations): error building libgo:
/scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:29:5: error: reference to undefined name 'randomTrap'
29 | if randomTrap == 0 {
| ^
/scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:38:34: error: reference to undefined name 'randomTrap'
38 | r1, _, errno := syscall.Syscall(randomTrap,
| ^
What's happening there is, I think, that the arm*b*-*-* case in
libgo/configure.ac is wrongly matching arm-glibc-linux-gnueabi with
the 'b' in the vendor part, and then something else is failing to
handle GOARCH=armbe. Given that you can have configurations with
multilibs of both endiannesses, endianness should always be detected
by configure.ac, for all architectures, using a compile test of
whether __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__, not based on textual
matches to the host (= target at top-level) triplet.
* armeb (all configurations): error building libada (for some reason
the Arm libada configuration seems to do different things for EH for
big-endian, which makes no sense to me and doesn't actually work):

* m68k: ICE in the Go front end building libgo

patch adds.
Note that I do not intend to run a build-many-glibcs.py bot with this
new option. If people concerned with libsanitizer, libgo or other
potentially affected GCC libraries wish to find out about such
problems more quickly, they may wish to run such a bot or bots (and to
monitor the results and fix issues found - obviously there will be
some overlap with issues found by my bots not using that option).
Note also that building a non-native Ada compiler requires a
sufficiently recent native (or build-x-host, in general) Ada compiler
to be used, possibly more or less the same version as being built.
That needs to be in the PATH when build-many-glibcs.py --full-gcc is
run; the script does not deal with setting up such a compiler (or any
of the other host tools needed for building GCC and glibc, beyond the
GMP / MPFR / MPC libraries), but perhaps it should, to avoid the need
to keep updating such a compiler manually when running a bot.
Tested by running build-many-glibcs.py with the new option, with
mainline GCC. There are build failures for various configurations,
which may be of interest to Go / Ada people even if you're not
interested in running such a bot:
* mips64 / mips64el (all configuration): ICE building libstdc++, as
seen without using the new option
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87156>.
* aarch64_be: error building libgo (little-endian aarch64 works fine):
version.go:67:13: error: expected ';' or ')' or newline
67 | BigEndian =
| ^
version.go:67:3: error: reference to undefined name 'BigEndian'
67 | BigEndian =
| ^
* arm (all configurations): error building libgo:
/scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:29:5: error: reference to undefined name 'randomTrap'
29 | if randomTrap == 0 {
| ^
/scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:38:34: error: reference to undefined name 'randomTrap'
38 | r1, _, errno := syscall.Syscall(randomTrap,
| ^
What's happening there is, I think, that the arm*b*-*-* case in
libgo/configure.ac is wrongly matching arm-glibc-linux-gnueabi with
the 'b' in the vendor part, and then something else is failing to
handle GOARCH=armbe. Given that you can have configurations with
multilibs of both endiannesses, endianness should always be detected
by configure.ac, for all architectures, using a compile test of
whether __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__, not based on textual
matches to the host (= target at top-level) triplet.
* armeb (all configurations): error building libada (for some reason
the Arm libada configuration seems to do different things for EH for
big-endian, which makes no sense to me and doesn't actually work):
a-exexpr.adb:87:06: "System.Exceptions.Machine" is not a predefined library unit
a-exexpr.adb:87:06: "Ada.Exceptions (body)" depends on "Ada.Exceptions.Exception_Propagation (body)"
a-exexpr.adb:87:06: "Ada.Exceptions.Exception_Propagation (body)" depends on "System.Exceptions.Machine (spec)"
* hppa: error building libgo (same error as for aarch64_be).
* ia64: ICE building libgo. I've filed
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87281> for this.
* m68k: ICE in the Go front end building libgo
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84948>.
* microblaze, microblazeel, nios2, sh3, sh3eb: build failure in libada
for lack of a libada port to those systems (I'm not sure sh3 would
actually need anything different from sh4):
a-cbdlli.ads:38:14: violation of restriction "No_Finalization" at system.ads:47
* i686-gnu: build failure in libada, might be fixed by the patch
attached to <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81103>
(not tested):
terminals.c:1115:13: fatal error: termio.h: No such file or directory
* scripts/build-many-glibcs.py (Context.__init__): Add full_gcc
argument.
(Config.build_gcc): Use --disable-libsanitizer for first GCC
build, but not for second build if --full-gcc. Use
--enable-languages=all for second build if --full-gcc.

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc

GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.
Command-line options to the script: -jN to run N jobs in parallel
(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).

Add build-many-glibcs.py support for building more GCC libraries.
Every so often we get libsanitizer or libgo builds breaking with new
glibc because of some change in the glibc headers.
glibc's build-many-glibcs.py deliberately disables libsanitizer and
GCC languages other than C and C++ because the point is to test glibc
and find glibc problems (including problems shown up by new compiler
warnings in new GCC), not to test libsanitizer or libgo; if the
compiler build fails because of libsanitizer or libgo failing to
build, that could hide the existence of new problems in glibc.
However, it seems reasonable to have a non-default mode where
build-many-glibcs.py does build those additional pieces, which this
patch adds.
Note that I do not intend to run a build-many-glibcs.py bot with this
new option. If people concerned with libsanitizer, libgo or other
potentially affected GCC libraries wish to find out about such
problems more quickly, they may wish to run such a bot or bots (and to
monitor the results and fix issues found - obviously there will be
some overlap with issues found by my bots not using that option).
Note also that building a non-native Ada compiler requires a
sufficiently recent native (or build-x-host, in general) Ada compiler
to be used, possibly more or less the same version as being built.
That needs to be in the PATH when build-many-glibcs.py --full-gcc is
run; the script does not deal with setting up such a compiler (or any
of the other host tools needed for building GCC and glibc, beyond the
GMP / MPFR / MPC libraries), but perhaps it should, to avoid the need
to keep updating such a compiler manually when running a bot.
Tested by running build-many-glibcs.py with the new option, with
mainline GCC. There are build failures for various configurations,
which may be of interest to Go / Ada people even if you're not
interested in running such a bot:
* mips64 / mips64el (all configuration): ICE building libstdc++, as
seen without using the new option
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87156>.
* aarch64_be: error building libgo (little-endian aarch64 works fine):
version.go:67:13: error: expected ';' or ')' or newline
67 | BigEndian =
| ^
version.go:67:3: error: reference to undefined name 'BigEndian'
67 | BigEndian =
| ^
* arm (all configurations): error building libgo:
/scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:29:5: error: reference to undefined name 'randomTrap'
29 | if randomTrap == 0 {
| ^
/scratch/jmyers/glibc/many9/src/gcc/libgo/go/internal/syscall/unix/getrandom_linux.go:38:34: error: reference to undefined name 'randomTrap'
38 | r1, _, errno := syscall.Syscall(randomTrap,
| ^
What's happening there is, I think, that the arm*b*-*-* case in
libgo/configure.ac is wrongly matching arm-glibc-linux-gnueabi with
the 'b' in the vendor part, and then something else is failing to
handle GOARCH=armbe. Given that you can have configurations with
multilibs of both endiannesses, endianness should always be detected
by configure.ac, for all architectures, using a compile test of
whether __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__, not based on textual
matches to the host (= target at top-level) triplet.
* armeb (all configurations): error building libada (for some reason
the Arm libada configuration seems to do different things for EH for
big-endian, which makes no sense to me and doesn't actually work):
a-exexpr.adb:87:06: "System.Exceptions.Machine" is not a predefined library unit
a-exexpr.adb:87:06: "Ada.Exceptions (body)" depends on "Ada.Exceptions.Exception_Propagation (body)"
a-exexpr.adb:87:06: "Ada.Exceptions.Exception_Propagation (body)" depends on "System.Exceptions.Machine (spec)"
* hppa: error building libgo (same error as for aarch64_be).
* ia64: ICE building libgo. I've filed
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87281> for this.
* m68k: ICE in the Go front end building libgo
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84948>.
* microblaze, microblazeel, nios2, sh3, sh3eb: build failure in libada
for lack of a libada port to those systems (I'm not sure sh3 would
actually need anything different from sh4):
a-cbdlli.ads:38:14: violation of restriction "No_Finalization" at system.ads:47
* i686-gnu: build failure in libada, might be fixed by the patch
attached to <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81103>
(not tested):
terminals.c:1115:13: fatal error: termio.h: No such file or directory
* scripts/build-many-glibcs.py (Context.__init__): Add full_gcc
argument.
(Config.build_gcc): Use --disable-libsanitizer for first GCC
build, but not for second build if --full-gcc. Use
--enable-languages=all for second build if --full-gcc.
(get_parser): Add --full-gcc option.
(main): Update call to Context.

Add script to build many glibc configurations.
This patch adds a Python (3.5 or later) script to build many different
configurations of glibc, including building the required cross
compilers first. It's not intended to change any patch testing
requirements, although some people may wish to use it for high-risk
patches such as adding warning options (and it can also be used to
test building, including compiling tests, for an individual
configuration, if e.g. you wish to do such a compilation test of a
patch for an architecture it touches).
The configurations include all the GNU/Linux ABI variants in
<https://sourceware.org/glibc/wiki/ABIList> (although some do not yet
build cleanly) and it would be desirable to cover enough other
variants e.g. for CPUs using different sysdeps directories to test
building each piece of code in glibc at least once. It would also be
desirable to extend it to cover Hurd and NaCl, which might best be
done by people familiar with those configurations.
You call the script as
build-many-glibcs.py /some/where thing-to-do <other-arguments>
where /some/where is a working directory for the script. It will
create and use subdirectories build, install, logs therein. You can
use it with thing-to-do being "checkout" to create a subdirectory src
therein, with subdirectories binutils, gcc, glibc, gmp, linux, mpc,
mpfr with the sources of those components, or create those directories
manually (all except glibc can be symlinks to sources elsewhere). In
the checkout case, by default it checks out GCC 6 branch, binutils
2.27 branch, glibc mainline and releases of other components. You can
specify <component>-<version> to choose a version to check out, where
<version> is "vcs-mainline" or "vcs-<branch>" to check out from
version control (only supported for gcc, binutils, glibc) and
otherwise a release version number to download and use a tarball;
components not specified on the command line have default versions
checked out. If you rerun "checkout" (with the same version
specifications) it will update checkouts from version control, but
will not detect cases where the location something is expected to be
checked out from has changed.
Other than "checkout", thing-to-do is one of host-libraries,
compilers, glibcs. So you run, in that order:
build-many-glibcs.py /some/where host-libraries
build-many-glibcs.py /some/where compilers
build-many-glibcs.py /some/where glibcs
host-libraries is run once and then those libraries are used for all
the compilers. compilers can be run once and then used many times for
testing different glibc versions (so a bot only needs to update glibc
and rerun the glibcs task, if using stable GCC / binutils; if testing
the latest versions of the whole toolchain together including mainline
GCC, it would probably want to update everything and rerun both
compilers and glibcs). You can also name particular variants after
"compilers" or "glibcs" to build just those variants (the possible
variants are hardcoded in the script).
I may add support for allowing the set of configurations to depend on
the GCC version (to get cleaner default results), and optionally
looping over architecture-independent glibc variants of CFLAGS and
configure options as well, for every glibc configuration listed
(e.g. -Os).
GCC versions before 4.9 are not expected to work (the code uses
--with-glibc-version to get the bootstrap GCC appropriately
configured). There are various problems for particular configurations
as well.

(default the number of CPU cores reported by the system); --keep=all
or --keep=failed to control keeping around build directories (default
--keep=none).
