* PowerPC: modf optimization fixAdhemerval Zanella2013-04-264-0/+4
| | | | | | | 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).
* PowerPC: modf optimizationAdhemerval Zanella2013-04-234-0/+108
| | | | | This patch implements modf/modff optimization for POWER by focus on FP operations instead of relying in integer ones.
* Refer to two GCC PRs.Thomas Schwinge2013-04-031-1/+2

* New <math.h> macro named issignaling to check for a signaling NaN (sNaN).Thomas Schwinge2013-04-021-0/+26
| | | | It is based on draft TS 18661 and currently enabled as a GNU extension.
* PowerPC: remove branch prediction from rint implementationAdhemerval Zanella2013-04-014-12/+12
| | | | | | | | 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.
* Remove usage of ONE macroSiddhesh Poyarekar2013-03-291-1/+1
| | | | I missed this instance, which caused a build failure in powerpc.
* Remove ZERO and MZERO macrosSiddhesh Poyarekar2013-03-291-10/+10

* PowerPC: .eh_frame info in crt1.o isn't useful and triggers gold bug 14675.Alan Modra2013-03-282-0/+14
| | | | | | | 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
* Fix e_logl (128ibm) spurious underflowAdhemerval Zanella2013-03-281-0/+6

* Make mantissa type of mp_no configurableSiddhesh Poyarekar2013-03-261-0/+56
| | | | | | | | | | 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.
* PowerPC: fix libm ABI issue for llroundlAdhemerval Zanella2013-03-261-0/+4
|
* PowerPC: fix sqrtl ABI issueAdhemerval Zanella2013-03-211-0/+4
| | | | This patch fixes a sqrtl ABI issue when building for powerpc64.
* Promote a math test for sNaN handling to the top-level.Thomas Schwinge2013-03-152-337/+0
|
* Use GCC's builtins for generating NaNs.Thomas Schwinge2013-03-151-55/+9

|
* Revert configurable mantissa patchSiddhesh Poyarekar2013-03-151-56/+0
| | | | | | Reverts d22ca8cdfb98001d03772ef264b244930d439b3f since it is severely broken on 32-bit.
* Make mantissa type configurableSiddhesh Poyarekar2013-03-151-0/+56
| | | | | This allows the default mantissa to be integral, with powerpc overriding it to take advantage of its FPUs.
* PowerPC: unify math_ldbl.h implementationsAdhemerval Zanella2013-03-082-162/+10
| | | | | This patch removes redudant definition from PowerPC specific math_ldbl, using the definitions from ieee754 math_ldbl.h.
* Consolidate copies of mp code in powerpcSiddhesh Poyarekar2013-03-086-221/+4
| | | | | Retain a single copy of the mp code in power4 instead of the two identical copies in powerpc32 and powerpc64.
