2013-04-26PowerPC: modf optimization fixAdhemerval Zanella
This patch fix the 3c0265394d9ffedff2b0de508602dc52e077ce5c commits by correctly setting minimum architecture for modf PPC optimization to power5+ instead of power5 (since only on power5+ round/ceil will be inline to inline assembly).
2013-04-23PowerPC: modf optimizationAdhemerval Zanella
This patch implements modf/modff optimization for POWER by focus on FP operations instead of relying in integer ones.
2013-04-03Refer to two GCC PRs.Thomas Schwinge
2013-04-02New <math.h> macro named issignaling to check for a signaling NaN (sNaN).Thomas Schwinge
It is based on draft TS 18661 and currently enabled as a GNU extension.
2013-04-01PowerPC: remove branch prediction from rint implementationAdhemerval Zanella
The branch prediction hints is actually hurts performance in this case. The assembly implementation make two assumptions: 1. 'fabs (x) < 2^52' is unlikely and 2. 'x > 0.0' is unlike (if 1. is true). Since it a general floating point function, expected input is not bounded and then it is better to let the hardware handle the branches.
2013-03-29Remove usage of ONE macroSiddhesh Poyarekar
I missed this instance, which caused a build failure in powerpc.

2013-03-28PowerPC: .eh_frame info in crt1.o isn't useful and triggers gold bug 14675.Alan Modra
The .eh_frame info in crt1.o isn't useful and this patch prevents it from being generated on PowerPC. It triggers the following gold bug: http://sourceware.org/bugzilla/show_bug.cgi?id=14675
2013-03-28Fix e_logl (128ibm) spurious underflowAdhemerval Zanella
2013-03-26Make mantissa type of mp_no configurableSiddhesh Poyarekar
The mantissa of mp_no is intended to take only integral values. This is a relatively good choice for powerpc due to its 4 fpus, but not for other architectures, which suffer due to this choice. This change makes the default mantissa a long integer and allows powerpc to override it. Additionally, some operations have been optimized for integer manipulation, resulting in a significant improvement in performance.
2013-03-26PowerPC: fix libm ABI issue for llroundlAdhemerval Zanella
2013-03-21PowerPC: fix sqrtl ABI issueAdhemerval Zanella
This patch fixes a sqrtl ABI issue when building for powerpc64.

2013-03-15Use GCC's builtins for generating NaNs.Thomas Schwinge
2013-03-15Better distinguish between NaN/qNaN/sNaN.Thomas Schwinge
2013-03-15Revert configurable mantissa patchSiddhesh Poyarekar
Reverts d22ca8cdfb98001d03772ef264b244930d439b3f since it is severely broken on 32-bit.
2013-03-15Make mantissa type configurableSiddhesh Poyarekar
This allows the default mantissa to be integral, with powerpc overriding it to take advantage of its FPUs.
2013-03-08PowerPC: unify math_ldbl.h implementationsAdhemerval Zanella
