0f122b8d12 Configuring for i386 is no longer supported.
We no longer support configuring for i386, nor do we
elide such a configuration to i686. Configuring with
i386-* is a failure, and we provide an example of
how to fix that.

206a669911 Write to bench.out-tmp only once
Appending benchmark program output on every run could result in a case
where the benchmark run was cancelled, resulting in a partially
written file.  This file gets used again on the next run, resulting in
results being appended to old results.

It could have been possible to remove the file before every benchmark
run, but it is easier to just write the output to bench.out-tmp only
once.

acb4325fc7 Rebuild benchmark sources when Makefile is updated
Benchmark programs are generated using parameters from the Makefile,
so it is necessary to rebuild them whenever the parameters in the
Makefile are updated.  Hence, added a dependency for the generated C
source on the Makefile so that it gets regenerated when the Makefile
is updated.

0a033d342e m68k: update libm test ULPs 2013-04-11 16:37:44 +02:00
Carlos O'Donell
aba5e333d4 libm-test.inc: Fix tests where cos(PI/2) != 0.
The value of PI is never exactly PI in any floating point representation,
and the value of PI/2 is never PI/2. It is wrong to expect cos(M_PI_2l)
to return 0, instead it will return an answer that is  non-zero because
M_PI_2l doesn't round to exactly PI/2 in the type used.

That is to say that the correct answer is to do the following:
* Take PI or PI/2.
* Round to the floating point representation.
* Take the rounded value and compute an infinite precision cos or sin.
* Use the rounded result of the infinite precision cos or sin as the
  answer to the test.

I used printf to do the type rounding, and Wolfram's Alpha to do the
infinite precision cos calculations.

The following changes bring x86-64 and x86 to 1/2 ulp for two tests.
It shows that the x86 cos implementation is quite good, and that
our test are flawed.

Unfortunately given that the rounding errors are type dependent we
need to fix this for each type. No regressions on x86-64 or x86.

01dc6df938 Don't use run-via-rtld-prefix for anything other than tests
run-via-rtld-prefix checks whether the program to be run is a static
test and skips if it is.  This is fine, except that it assumes that
the program to be run is the second $^, which is true only for tests.

This change creates an rtld-prefix, which is simply the dynamic linker
prefix with the necessary arguments and uses that in the non-test
targets.

abe7f530bf Accept leading and trailing spaces in getdate input string
Fixes #15346.

The POSIX description of getdate allows for extra spaces in the
getdate input string.  __getdate_r uses strptime internally, which
works fine with extra spaces between format strings (and hence within
an input string) but not with leading and trailing spaces.  So we trim
off the leading and trailing spaces before we pass it on to strptime.

26510bdda1 New Makefile target `regen-ulps'.
The wiki "Regeneration" page has this to say about update ULPs.

"The libm-test-ulps files are semiautomatically updated. To
update an ulps baseline, run each of the failing tests (test-float,
 test-double, etc.) with -u; this will generate a file called ULPs;
concatenate each of those files with the existing libm-test-ulps
file, after removing any entries for particularly huge numbers of
ulps that you do not want to mark as expected. Then run
gen-libm-test.pl -n -u FILE where FILE is the concatenated file
produced in the previous step. This generates a file called
NewUlps which is the new sorted version of libm-test-ulps."

The same information is listed in math/README.libm-test, and is a
lot of manual work that you often want to run over-and-over again
while working on a particular test.

The `regen-ulps' convenience target does this automatically for
developers.

We strictly assume the source tree is readonly and add a
new --output-dir option to libm-test.inc to allow for writing
out ULPs to $(objpfx).

When run the new target does the following:
* Starts with the baseline ULPs file.
* Runs each of the libm math tests with -u.
* Adds new changes seen with -u to the baseline.
* Sorts and prepares the test output with gen-libm-test.pl.
* Leaves math/NewUlps in your build tree to copy to your source
  tree, cleanup, and checkin.

The math test documentation in math/README.libm-test is updated
document the new Makefile target.

a01f19c8fb i386: Fail at configure time for i386 builds.
This change does two things:

* Treats a target i386-* as if it were i686.
* Fails configure if the user is generating code
  for i386.

We no longer support i386 code-generation because the i386
lacks the atomic operations we need in glibc.

You can still configure for i386-*, but you get i686 code.

You can't build with --march=i386, --mtune=i386 or a compiler
that defaults to i386 code-generation.

I've added two i386 entries in the master todo list to discuss
merging and renaming:
http://sourceware.org/glibc/wiki/Development_Todo/Master#i386

The failure modes are fail-safe here. You compile for i386,
get i686, and try to run on i386 and it fails. The configure
log has a warning saying we elided to i686. There is no situation
that I can see where we run into any serious problems.

The patch makes the current state better in that we get less
confused users and we build successfully in more default
configurations.

The next enhancement would be to add --march=i?86
as suggested in #c20 of BZ#10062 for any i?86-* builds, which
would solve the problem of a 32-bit compiler that defaults to
i386 code-gen and glibc configured for i686-* target. Which
previously failed at build time, and now will fail at configure
time (requires adding --march=i686).

Updated NEWS with BZ #10060 and #10062.

No regressions.

9ac3b5047e Fix static build when configured with --disable-hidden-plt
Fixes BZ #15337.

Static builds fail with the following warning:

/home/tools/glibc/glibc/nptl/../nptl/sysdeps/unix/sysv/linux/x86_64/cancellation.S:80:
undefined reference to `__GI___pthread_unwind'

When the source is configured with --disable-hidden-plt.  This is
because the preprocessor conditional in cancellation.S only checks if
the build is for SHARED, whereas hidden_def is defined appropriately
only for a SHARED build that will have symbol versioning *and* hidden
defs are enabled.  The last case is false here.

d755bba40f Preserve errno across _PC_CHOWN_RESTRICTED call on XFS
Fix BZ #15305.

On kernel versions earlier than 2.6.29, the Linux kernel exported a
sysctl called restrict_chown for xfs, which could be used to allow
chown to users other than the owner.  2.6.29 removed this support,
causing the open_not_cancel_2 to fail and thus modify errno.  The fix
is to save and restore errno so that the caller sees it as unmodified.

Additionally, since the code to check the sysctl is not useful on
newer kernels, we add an ifdef so that in future the code block gets
rmeoved completely.
