* Fix build on pre-v9 32-bit Sparc.David S. Miller2013-11-061-1/+2
| | | | | | | | | We cannot use fnegd in this code, as fnegd was added in v9. Only fnegs exists in v8 and earlier. [BZ #15985] * sysdeps/sparc/sparc32/fpu/s_fdim.S (__fdim): Do not use fnegd on pre-v9 cpus, use a fnegs+fmovs sequence instead.
* rename configure.in to configure.acMike Frysinger2013-10-302-1/+1
| | | | | | | Autoconf has been deprecating configure.in for quite a long time. Rename all our configure.in and preconfigure.in files to .ac. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Update sparc ULPs.David S. Miller2013-10-101-0/+125
| | | | * sysdeps/sparc/fpu/libm-test-ulps: Update.
* soft-fp: fix negation NaN handling (bug 16034).Joseph Myers2013-10-101-5/+2

* BZ #15754: CVE-2013-4788Carlos O'Donell2013-09-232-0/+6
| | | | | | | | | | | | The pointer guard used for pointer mangling was not initialized for static applications resulting in the security feature being disabled. The pointer guard is now correctly initialized to a random value for static applications. Existing static applications need to be recompiled to take advantage of the fix. The test tst-ptrguard1-static and tst-ptrguard1 add regression coverage to ensure the pointer guards are sufficiently random and initialized to a default value.

* Update Sparc ULPs.David S. Miller2013-07-201-0/+5
| | | | | * sysdeps/sparc/fpu/libm-test-ulps: Update ULPs to handle minor difference between 32-bit and 64-bit.

* Avoid crashing in LD_DEBUG when program name is unavailableSiddhesh Poyarekar2013-05-292-4/+2
| | | | | | | | | Resolves: #15465 The program name may be unavailable if the user application tampers with argc and argv[]. Some parts of the dynamic linker caters for this while others don't, so this patch consolidates the check and fallback into a single macro and updates all users.
* Don't include expected results in libm-test test names.Joseph Myers2013-05-221-2470/+2470
|
* Handle sincos with generic libm-test logic.Joseph Myers2013-05-191-7/+7
|
* MIPS: soft-fp NaN representation correctionsMaciej W. Rozycki2013-05-162-0/+2
| | | | | | | | [BZ #15442] This adds support for the inverse interpretation of the quiet bit of IEEE 754 floating-point NaN data that some processors use. This includes in particular MIPS architecture processors; the payload used for the canonical qNaN encoding is updated accordingly so as not to interfere with the quiet bit.
