2013-05-24tile: improve detection for missing -mcmodel=large supportChris Metcalf4-4/+41
The existing test avoided passing -mcmodel=large if the compiler didn't support it. However, we need to test not just the compiler support, but also the toolchain (as and ld) support, so make the test more complete. In addition, we have to avoid using the hwN_plt() assembly operators if that support is missing, so guard the uses with #ifdef NO_PLT_PCREL. This allows us to properly build glibc with the current community binutils, which doesn't yet have the PC-relative PLT operator support. The -mcmodel=large support is in gcc 4.8, but the toolchain support won't be present in the community until binutils 2.24.

2013-05-22Update bits/siginfo.h with Linux hwpoison SIGBUS changesEdjunior Barbosa Machado8-5/+59
Adds new SIGBUS error codes for hardware poison signals, syncing with the current kernel headers (v3.9). It also adds si_trapno field for alpha.

2013-05-16MIPS: soft-fp NaN representation correctionsMaciej W. Rozycki9-6/+46
[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.

2013-05-15hppa: Cleanup libm-test-ulps.Carlos O'Donell2-420/+3
Joseph Myers noted that there were several old and really very incorrect values in the hppa libm-test-ulps. This patch removes all of the ulps values for ceil, floor, rint, round, trun, llrint, and llround, all of which were previously incorreclty added (including some negative values which are really wrong). --- ports/ 2013-05-15 Carlos O'Donell <carlos@redhat.com> * sysdeps/hppa/fpu/libm-test-ulps: Remove old values for ceil, floor, rint, round, trunc, llrint, and llround.
2013-05-15hppa: Update libm-test-ulpsCarlos O'Donell2-15/+4168
Update libm-test-ulps for hppa. There are a few entries with 4 or 5 ulps, but these appear to be expected. A more thorough review will be required if hppa switches long-double to a different type. --- ports/ 2013-05-15 Carlos O'Donell <carlos@redhat.com> * sysdeps/hppa/fpu/libm-test-ulps: Regenerate.
2013-05-15hppa: Fix _FPU_GETCW and _FPU_SETCW.Carlos O'Donell2-2/+9
The following patch fixes both _FPU_GETCW and _FPU_SETCW for hppa. The initial implementation was flawed and not well tested. We failed to set cw, and passed in the value of a register to fldd. This patch fixes both of those errors and allows the libm tests to pass without failure.

2013-03-12ia64: fix set-but-unused warnings with syscallsMike Frysinger2-2/+11
These macros often set up a variable that later macros sometimes do not use. Add unused attribute to avoid that. Similarly, the ia64 code tends to check the err field rather than the val (which is opposite of most arches) leading to the same kind of warning. Replace this with a dummy reference.

2013-03-12ia64: fix strict aliasing warnings with libm errorMike Frysinger2-58/+81
The current code declares double constants by using a char buffer and then casting the pointer to a different type. This makes the aliasing logic unhappy. Change it to use a union instead to avoid that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-03-12ia64: fix strict aliasing warnings with func descriptorsMike Frysinger5-13/+34
Function pointers on ia64 are like parisc -- they're plabels. While the parisc port enjoys a gcc builtin for extracting the address here, ia64 has no such luck. Casting & dereferencing in one go triggers a strict aliasing warning. Use a union to fix that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
