This patch moves tests of clog10 to auto-libm-test-in. Note that this
means gen-auto-libm-tests will now depend on the recent MPC 1.0.2
release which added a fix for a bug that made gen-auto-libm-tests hang
for clog10. (It still can't conveniently be used for cacos cacosh
casin casinh catan catanh csin csinh because of extreme slowness of
those functions for special cases in MPC; at least some slow cases of
csin / csinh are fixed in MPC trunk, but not in a release.)
Tested x86_64 and x86 and ulps updated accordingly.
* math/auto-libm-test-in: Add tests of clog10.
* math/auto-libm-test-out: Regenerated.
* math/libm-test.inc (clog10_test_data): Use AUTO_TESTS_c_c.

This patch moves tests of fma to auto-libm-test-in, adding the
required support to gen-auto-libm-tests.
Because fma can have exact zero results depending on the rounding
mode, results of fma cannot always be determined from a single value
computed in higher precision with a sticky bit. Thus, this patch adds
support for recomputing results with the original MPFR/MPC function in
the case where an exact zero is involved. (This also affects some
results for cpow; when we start testing cpow in all rounding modes, I
think it will be most appropriate to make those tests use
IGNORE_ZERO_INF_SIGN, since ISO C does not attempt to determine signs
of zero results, or special caes in general, for cpow, and I think
signs of zero for cpow are beyond the scope of glibc's accuracy
goals.)
Simply treating the existing test inputs for fma like those for other
functions (i.e., as representing the given value rounded up or down to
any of the supported floating-point formats) increases the size of
auto-libm-test-out by about 16MB (i.e., about half the file is fma
test data). While rounded versions of tests are perfectly reasonable
test inputs for fma, in this case having them seems excessive, so this
patch allows functions to specify in gen-auto-libm-tests that the
given test inputs are only to be interpreted exactly, not as
corresponding to values rounded up and down. This reduces the size of
the generated test data for fma to a more reasonable 2MB.
A consequence of this patch is that fma is now tested for correct
presence or absence of "inexact" exceptions, where previously this
wasn't tested because I didn't want to try to add that test coverage
manually to all the existing tests. As far as I know, the existing
fma implementations are already correct in this regard.
This patch provides the first cases where the gen-auto-libm-tests
support for distinguishing before-rounding/after-rounding underflow
actually produces separate entries in auto-libm-test-out (for
functions without exactly determined results, the affected cases are
all considered underflow-optional, so this only affects functions like
fma with exactly determined results). I didn't see any signs of
problems with this logic in the output.
Tested x86_64 and x86.

gen-auto-libm-tests has a bug in the logic for setting a sticky bit
based on the ternary value from MPFR: it is correct for positive
results, but for negative results mpz_setbit acts as if a two's
complement representation is used, whereas the low bit needs setting
based on the sign-magnitude representation GMP actually uses. (This
showed up in converting fma tests to use auto-libm-test-in /
gen-auto-libm-tests.)
This patch fixes the problem by negating the mpz_t value to set its
low bit. There are lots of changes to auto-libm-test-out (mainly 1ulp
fixes to ldbl-128 expected results), but only a few ulps updates are
needed on x86 / x86_64. In one case, a corrected expectation showed
up a spurious underflow exception where the correct result is slightly
outside the underflowing range.
Tested x86_64 and x86 and ulps updated accordingly.

This patch, an updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00193.html>, starts
the process of generating explicit PASS or FAIL status for individual
glibc tests. It's based on Tomas Dohnalek's patch
<https://sourceware.org/ml/libc-alpha/2012-10/msg00278.html>, but is
deliberately more minimal: it doesn't try to cover any tests outside
of $(tests) / $(xtests) (that's for a later patch), nor does it put
the result together in an overall summary file (again, a later patch):
it just generates the .test-result files.
Thus, this patch keeps the overall logic for when a testsuite run
finishes completely unchanged: a test failing will terminate the run.
I think we *should* move to a more conventional approach where plain
"make check" does not terminate for an individual test failure, unless
e.g. you say "make stop-on-test-failure=y check", but that sort of
policy change is best done as a separate patch once the infrastructure
is in place to generate summary files for completed test runs (which
will entirely consist of PASS and XFAIL lines if the testsuite run
reaches the point of generating them, until such a policy change is
made).
Tested x86_64.

Most glibc tests that use mtrace to verify that there were no memory
leaks from the glibc facilities used in a given test depend on the
.out file of the previous test so that the mtrace test runs mtrace and
nothing else.
Two, however, have a single target combining mtrace with something
else. In the case of libio/tst-fopenloc.check, the test both compares
the output with an expected baseline and runs mtrace. In the case of
posix/tst-rxspencer-mem, the test is run (with different command line
from the main run) and then mtrace is run, from the same makefile
target.
This patch splits both of these tests up to use separate makefile
targets for each thing tested; in the tst-rxspencer case, a file
tst-rxspencer-no-utf8.c is created that just includes tst-rxspencer.c,
as is usual for tests where the same code gets tested in different
compile-time or runtime configurations.
Adding $(evaluate-test) to test commands, as in
<https://sourceware.org/ml/libc-alpha/2014-01/msg00194.html>, will no
longer need to insert && between multiple commands, as all tests will
either have just a single command or already use &&.
Tested x86_64.

* posix/tst-rxspencer-no-utf8.c: New file.
This patch splits makefile rules that generate a file then run cmp to
check the contents of that file into separate rules to generate and
compare the file. This simplifies making those tests generate PASS /
FAIL results, by removing the need to insert && between commands in
the test so that a $(evaluate-test) call is reached. It also avoids
the oddity of the .out file being an intermediate file rather than the
final result generated, as noted for some of these tests in
<https://sourceware.org/ml/libc-alpha/2012-10/msg00894.html>.
In many cases, the rule to run the program was no longer needed
because the default rules for running test programs on the host to
generate a .out file sufficed. (I'm not asserting the commands run
after this patch are *exactly* the same as before, simply that the
rules did nothing special that appeared deliberate or relevant to
anything about what the tests were testing. In cases where the rules
redirected stderr as well as stdout, I left the existing rule's
redirection in place to avoid changing what gets compared with the
expected results.)
It's clear there is a lot in common between the various -cmp.out rules
and it might be possible in future to refactor them into more generic
support for the case of comparing test output against a baseline.
(Some baselines are *.exp, some *.expect, some directly embedded in
the makefiles, and nptl/tst-cleanupx0.expect appears unused.)

This patch cleans up cases of __USE_MISC that are trivially redundant
after the recent substitution of __USE_MISC for __USE_BSD and
__USE_SVID: either in constructs such as "defined __USE_MISC ||
defined __USE_MISC", or else (in the bits/mman.h case) a conditional
on __USE_MISC nested inside another __USE_MISC conditional. (The
cleanups remaining after this patch are still quite large, but it
seems a reasonable piece to separate out.)

GCC trunk now uses soft-fp for MIPS64 long double, so supporting

The toplevel Makefile's subdir_targets variable refers to
subdir_lint.out. As far as I can tell, this is not defined or
referenced anywhere else in the tree. Having .out makefile references
that don't refer to the output from testcases seems confusing; this
patch removes the reference to subdir_lint.out.
Tested x86_64.
* Makefile (subdir_targets): Remove subdir_lint.out.
stdio-common/Makefile has the tests target depend on two test output
files indirectly through rules do-tst-unbputc and do-tst-printf. I
see no reason for such an indirection, and everywhere else the tests
just depend on the output files directly, so this patch removes the
indirection.

If you rerun "make check" in a tree where some tests have already been
run, it will rerun io/ftwtest-sh because that test uses ftwtest.out,
the same name to which output is redirected, as its internal temporary
file, and then removes it on exit.
Clearly tests should not be removing the files to which their output
is redirected like that. This patch changes the script to use a
different file as its internal temporary file, so the actual output
referenced in the makefile isn't removed.
Tested x86_64.
* io/ftwtest-sh (testout): Change to $tmp/ftwtest-tmp.out.
If you rerun "make check" in a tree where some tests have already been
run, it will rerun ABI tests because those do not create an output

This patch changes those tests to create .out files so they only get
rerun if the dependencies (on the ABI baselines and the generated
.symlist files) indicate they should be rerun.

IEEE 754-2008 defines two ways in which tiny results can be detected,
"before rounding" (based on the infinite-precision result) and "after
rounding" (based on the result when rounded to normal precision as if
the exponent range were unbounded). All binary operations on an
architecture must use the same choice of how tininess is detected.
soft-fp has so far implemented only before-rounding tininess
detection. This patch adds support for after-rounding tininess
detection. A new macro _FP_TININESS_AFTER_ROUNDING is added that
sfp-machine.h must define (soft-fp is meant to be self-contained so
the existing tininess.h files aren't used here, though the information
going in sfp-machine.h has been taken from them). The soft-fp macros
dealing with raising underflow exceptions then handle the cases where
the choice matters specially, rounding a copy of the input to the
appropriate precision to see if a value that's tiny before rounding
isn't tiny after rounding.
Tested for mips64 using GCC trunk (which now uses soft-fp on MIPS, so
supporting exceptions and rounding modes for long double where not
previously supported - this is the immediate motivation for doing this
patch now) together with (a) a patch to sysdeps/mips/math-tests.h to
enable exceptions / rounding modes tests for long double for GCC 4.9
and later, and (b) corresponding changes applied to libgcc's soft-fp
and sfp-machine.h files. In the libgcc context this is also tested on
x86_64 (also an after-rounding architecture) with testcases for
__float128 that I intend to add to the GCC testsuite when updating
soft-fp there.
(To be clear: this patch does not fix any glibc bugs that were
user-visible in past releases, since after-rounding architectures
didn't use soft-fp in any affected case with support for
floating-point exceptions - so there is no corresponding Bugzilla bug.
Rather, it works together with the GCC changes to use soft-fp on MIPS
to allow previously absent long double functionality to work properly,
and allows soft-fp to be used in glibc on after-rounding architectures
in cases where it couldn't previously be used.)

MIPS has its own version of dl-lookup.c to deal with differences
between undefined symbol semantics in the PIC and non-PIC ABIs. This
is often liable to get out of date with respect to the generic file
(for example, the recent __builtin_expect changes didn't cover ports,
and it's not obvious to anyone changing dl-lookup.c that there would
be architecture-specific versions).
This patch adds a macro that dl-machine.h can define that is used in
the appropriate place in dl-lookup.c, so that MIPS no longer needs its
own version of that file.
Tested for mips64 that the only changes to disassembly of installed

I've moved the MIPS port from ports to the main sysdeps hierarchy.

git mv ports/sysdeps/mips sysdeps/mips
git mv ports/sysdeps/unix/mips sysdeps/unix/mips
git mv ports/sysdeps/unix/sysv/linux/mips sysdeps/unix/sysv/linux/mips
and in addition to the ChangeLog entries here, I put a note at the top
of ports/ChangeLog.mips similar to those in other files.

same before and after this patch (except for ld.so where paths in

This patch prepares for moving mips from ports to libc by reversing
the #include ordering between mips and hppa.
Reversing #include ordering for umount.c is the conservative change in
preparation for moving the mips port. In fact, it appears there are
several redundant umount.c files all implementing umount in terms of
the umount2 syscall; I've filed bug 16552 for eliminating that
redundancy properly.
Tested that disassembly of shared libraries for mips (o32, n32, n64)
is the same before and after this patch.
* sysdeps/unix/sysv/linux/hppa/umount.c: Move to
sysdeps/unix/sysv/linux/mips/mips64/umount.c and #include that
file.
* sysdeps/unix/sysv/linux/mips/mips64/umount.c: Move from
sysdeps/unix/sysv/linux/hppa/umount.c instead of #include of that
file.
This patch removes an unnecessary dependency of the mips port on alpha
by including a powerpc file directly where previously the mips file
included the alpha one which then included the powerpc one.
* sysdeps/unix/sysv/linux/mips/ipc_priv.h: Directly include
sysdeps/unix/sysv/linux/powerpc/ipc_priv.h instead of via
sysdeps/unix/sysv/linux/alpha/ipc_priv.h.
I've moved the TILE-Gx and TILEPro ports to the main sysdeps hierarchy,
along with the linux-generic ports infrastructure. Beyond the README
update, the move was just
git mv ports/sysdeps/tile sysdeps/tile
git mv ports/sysdeps/unix/sysv/linux/tile \
sysdeps/unix/sysv/linux/tile
git mv ports/sysdeps/unix/sysv/linux/generic \
sysdeps/unix/sysv/linux/generic
I updated the relevant ChangeLogs along the lines of the ARM move
in commit c6bfe5c4d7 and tested the 64-bit tilegx build to confirm that
there were no changes in "objdump -dr" output in the shared objects.
When debugging failures in this test, it's helpful to see as much output
as possible. So rather than returning immediately, let the code run as
far as it can. We still mark failures as soon as they happen.

Make sure the longjmp checking logic catches stacks that are slightly
outside of a valid alternative signal stack.
