2013-05-17Prevent optimizing out of benchmark function callSiddhesh Poyarekar4-3/+10
Resolves: #15424 The compiler would optimize the benchmark function call out of the loop and call it only once, resulting in blazingly fast times for some benchmarks (notably atan, sin and cos). Mark the inputs as volatile so that the code is forced to read again from the input for each iteration.

2013-05-16MIPS: soft-fp NaN representation correctionsMaciej W. Rozycki15-18/+124
[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.

2013-05-15Remove const attribute on get_log2Peter Collingbourne2-1/+4
This function is not const, as it can modify log2_m and log2_m_inited.
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.

2013-05-15Use movq for 64-bit operationsPeter Collingbourne2-2/+8
The EXTRACT_WORDS64 and INSERT_WORDS64 macros use movd for a 64-bit operation. Somehow gcc manages to turn this into movq, but LLVM won't. 2013-05-15 Peter Collingbourne <pcc@google.com> * sysdeps/x86_64/fpu/math_private.h (MOVQ): New macro. (EXTRACT_WORDS64) Use where appropriate. (INSERT_WORDS64) Likewise.
2013-05-15Use x constraints for operands to vfmaddss and vfmaddsdPeter Collingbourne3-2/+6
While these instructions accept memory operands, only one operand may be a memory operand. Giving two operands xm constraints gives the compiler the option of using memory for both operands, which would result in invalid assembly code. Using x for all operands is more appropriate, as most x86_64 calling conventions will pass the arguments in registers anyway. 2013-05-15 Peter Collingbourne <pcc@google.com> * sysdeps/x86_64/fpu/multiarch/s_fma.c (__fma_fma4): Replace xm constraints with x constraints. * sysdeps/x86_64/fpu/multiarch/s_fmaf.c (__fmaf_fma4): Likewise.
2013-05-15Move _obstack_compat out of commonPeter Collingbourne2-1/+5
it is impossible to create an alias of a common symbol (as compat_symbol does), because common symbols do not have a section or an offset until linked. GNU as tolerates aliases of common symbols by simply creating another common symbol, but other assemblers (notably LLVM's integrated assembler) are less tolerant. 2013-05-15 Peter Collingbourne <pcc@google.com> * malloc/obstack.c (_obstack_compat): Add initializer. -
2013-05-15Reserve new TLS field for x86 and x86_64Andreas Jaeger4-11/+21
[BZ #10686] * sysdeps/x86_64/tls.h (struct tcbhead_t): Add __private_ss field. * sysdeps/i386/tls.h (struct tcbhead_t): Likewise.

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'Donell3-8/+15
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. Signed-off-by: Guy Martin <gmsoft@tuxicoman.be> Signed-off-by: Carlos O'Donell <carlos@redhat.com> --- 2013-05-15 Guy Martin <gmsoft@tuxicoman.be> Carlos O'Donell <carlos@redhat.com> [BZ# 15000] * ports/sysdeps/hppa/fpu/fpu_control.h (_FPU_GETCW): Set cw. (_FPU_SETCW): Pass address to fldd.

2013-05-14Add comments to vDSO hwcap loading process.Carlos O'Donell3-1/+25
Loading of the vDSO pseudo-hwcap from the type 2 GNU note is a rather arcane and poorly documented process. Given that I had a chance to review this code today I thought I would add all of the things I had to lookup to verify the validity of the process. With a single .note.GNU the vDSO can register up to 64 flags, though in practice you are limited to 64 - _DL_FIRST_EXTRA bits which on x86 is 12 bits. The only use of this that I know of is in the Xen support in Linux where they use the 1st bit to indicate "nosegneg". I see "We use bit 1 to avoid bugs in some versions of glibc when bit 0 is used; the choice is otherwise arbitrary.", but no reference to a glibc bug anywhere. The code as-is should support bit zero, so we still have that free for future use. The kernel, glibc, and ld.so.cache must coordinate to ensure that bit values don't go too high and are used consistently. --- 2013-05-13 Carlos O'Donell <carlos@redhat.com> * elf/dl-hwcaps.c (_dl_important_hwcaps): Comment vDSO hwcap loading. * elf/ldconfig.c (is_hwcap_platform): Comment each hwcap check. (main): Comment "tls" pseudo-hwcap.
