2013-12-13PowerPC: Cleaning up uneeded sqrt routinesAdhemerval Zanella
For PPC64, all the wrappers at sysdeps are superfluous: they are basically the same implementation from math/w_sqrt.c with the '#ifdef _IEEE_LIBM'. And the power4 version just force the 'fsqrt' instruction utilization with an inline assembly, which is already handled by math_private.h __ieee754_sqrt implementation.

2013-11-26PowerPC: Fix __fe_nomask_env missing symbolAdhemerval Zanella
This patch fix the missing symbol __fe_nomask_env from commit 41e8926aa4b7f17bc95984737ee82a254ad0911c for GLIBC_2.1.
2013-11-25PowerPC: Set/restore rounding mode only when neededAdhemerval Zanella
This patch helps some math functions performance by adding the libc_fexxx variant of inline functions to handle both FPU round and exception set/restore and by using them on the libc_fexxx_ctx functions. It is based on already coded fexxx family functions for PPC with fpu. Here is the summary of performance improvements due this patch (measured on a POWER7 machine): Before: cos(): ITERS:9.5895e+07: TOTAL:5116.03Mcy, MAX:77.6cy, MIN:49.792cy, 18744 calls/Mcy exp(): ITERS:2.827e+07: TOTAL:5187.15Mcy, MAX:494.018cy, MIN:38.422cy, 5450.01 calls/Mcy pow(): ITERS:6.1705e+07: TOTAL:5144.26Mcy, MAX:171.95cy, MIN:29.935cy, 11994.9 calls/Mcy sin(): ITERS:8.6898e+07: TOTAL:5117.06Mcy, MAX:83.841cy, MIN:46.582cy, 16982 calls/Mcy tan(): ITERS:2.9473e+07: TOTAL:5115.39Mcy, MAX:191.017cy, MIN:172.352cy, 5761.63 calls/Mcy After: cos(): ITERS:2.05265e+08: TOTAL:5111.37Mcy, MAX:78.754cy, MIN:24.196cy, 40158.5 calls/Mcy exp(): ITERS:3.341e+07: TOTAL:5170.84Mcy, MAX:476.317cy, MIN:15.574cy, 6461.23 calls/Mcy pow(): ITERS:7.6153e+07: TOTAL:5129.1Mcy, MAX:147.5cy, MIN:30.916cy, 14847.2 calls/Mcy sin(): ITERS:1.58816e+08: TOTAL:5115.11Mcy, MAX:1490.39cy, MIN:22.341cy, 31048.4 calls/Mcy tan(): ITERS:3.4964e+07: TOTAL:5114.18Mcy, MAX:177.422cy, MIN:146.115cy, 6836.68 calls/Mcy
2013-11-13PowerPC: Fix __fe_mask_env exportAdhemerval Zanella
This patch does not export __fe_mask_env anymore, only providing a compatibility symbol. It fixes BZ#14143.
2013-10-04PowerPC floating point little-endian [11 of 15]Alan Modra

http://sourceware.org/ml/libc-alpha/2013-07/msg00201.html These two functions oddly test x+1>0 when a double x is >= 0.0, and similarly when x is negative. I don't see the point of that since the test should always be true. I also don't see any need to convert x+1 to integer rather than simply using xr+1. Note that the standard allows these functions to return any value when the input is outside the range of long long, but it's not too hard to prevent xr+1 overflowing so that's what I've done. (With rounding mode FE_UPWARD, x+1 can be a lot more than what you might naively expect, but perhaps that situation was covered by the x - xrf < 1.0 test.) * sysdeps/powerpc/fpu/s_llround.c (__llround): Rewrite. * sysdeps/powerpc/fpu/s_llroundf.c (__llroundf): Rewrite.
2013-10-04PowerPC floating point little-endian [9 of 15]Alan Modra
http://sourceware.org/ml/libc-alpha/2013-07/msg00200.html This works around the fact that vsx is disabled in current little-endian gcc. Also, float constants take 4 bytes in memory vs. 16 bytes for vector constants, and we don't need to write one lot of masks for double (register format) and another for float (mem format). * sysdeps/powerpc/fpu/s_float_bitwise.h (__float_and_test28): Don't use vector int constants. (__float_and_test24, __float_and8, __float_get_exp): Likewise.

http://sourceware.org/ml/libc-alpha/2013-08/msg00083.html Further replacement of ieee854 macros and unions. These files also have some optimisations for comparison against 0.0L, infinity and nan. Since the ABI specifies that the high double of an IBM long double pair is the value rounded to double, a high double of 0.0 means the low double must also be 0.0. The ABI also says that infinity and nan are encoded in the high double, with the low double unspecified. This means that tests for 0.0L, +/-Infinity and +/-NaN need only check the high double. * sysdeps/ieee754/ldbl-128ibm/e_atan2l.c (__ieee754_atan2l): Rewrite all uses of ieee854 long double macros and unions.
