* PowerPC: update missing CL/NEWS bug referenceAdhemerval Zanella2013-05-202-1/+2
| | | | | | Update ChangLog bugzilla number and NEWS for commit 13d3b41a36c4f28d171a144f8a9baad3a8835981 (PowerPC: fix hypot/hypotf check for -INF).
* Faster memset on x64Ondrej Bilka2013-05-202-1315/+96
| | | | | | | | | This implementation speed up memset in several ways. First is avoiding expensive computed jump. Second is using fact that arguments of memset are most of time aligned to 8 bytes. Benchmark results on: kam.mff.cuni.cz/~ondra/benchmark_string/memset_profile_result27_04_13.tar.bz2
* Faster memcpy on x64.Ondrej Bilka2013-05-205-8/+195
| | | | | | | | | We add new memcpy version that uses unaligned loads which are fast on modern processors. This allows second improvement which is avoiding computed jump which is relatively expensive operation. Tests available here: http://kam.mff.cuni.cz/~ondra/memcpy_profile_result27_04_13.tar.bz2

* Prevent optimizing out of benchmark function callSiddhesh Poyarekar2013-05-174-3/+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.
* PowerPC: fix hypot/hypotf check for -INFAdhemerval Zanella2013-05-173-6/+12

* MIPS: soft-fp NaN representation correctionsMaciej W. Rozycki2013-05-1615-18/+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.

* Remove const attribute on get_log2Peter Collingbourne2013-05-152-1/+4
| | | | This function is not const, as it can modify log2_m and log2_m_inited.
* hppa: Cleanup libm-test-ulps.Carlos O'Donell2013-05-152-420/+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.

* Use movq for 64-bit operationsPeter Collingbourne2013-05-152-2/+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.
* Use x constraints for operands to vfmaddss and vfmaddsdPeter Collingbourne2013-05-153-2/+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.
* Move _obstack_compat out of commonPeter Collingbourne2013-05-152-1/+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. -
* Reserve new TLS field for x86 and x86_64Andreas Jaeger2013-05-154-11/+21
| | | | | | | [BZ #10686] * sysdeps/x86_64/tls.h (struct tcbhead_t): Add __private_ss field. * sysdeps/i386/tls.h (struct tcbhead_t): Likewise.
* Update s390/bits/siginfo.hEdjunior Machado2013-05-152-3/+15
| | | | | | | | | | 2013-05-15 Edjunior Machado <emachado@linux.vnet.ibm.com> * sysdeps/unix/sysv/linux/s390/bits/siginfo.h (siginfo_t): Remove si_trapno and add si_addr_lsb to _sifields.sigfault. (si_trapno): Remove macro. (si_addr_lsb): Define new macro. (BUS_MCEERR_AR, BUS_MCEERR_AO): Define new values.

* hppa: Update libm-test-ulpsCarlos O'Donell2013-05-152-15/+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.
* hppa: Fix _FPU_GETCW and _FPU_SETCW.Carlos O'Donell2013-05-153-8/+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.
