* x86-64: Exclude FMA4 IFUNC functions for -mapxfH.J. Lu2024-04-061-9/+13
| | | | | | | | | | When -mapxf is used to build glibc, the resulting glibc will never run on FMA4 machines. Exclude FMA4 IFUNC functions when -mapxf is used. This requires GCC which defines __APX_F__ for -mapxf with commit: 1df56719bd8 x86: Define __APX_F__ for -mapxf Reviewed-by: Sunil K Pandey <skpgkp2@gmail.com>
* x86_64: Exclude SSE, AVX and FMA4 variants in libm multiarchSunil K Pandey2024-02-251-72/+76
| | | | | | | | | | | | | | | | | | | When glibc is built with ISA level 3 or higher by default, the resulting glibc binaries won't run on SSE or FMA4 processors. Exclude SSE, AVX and FMA4 variants in libm multiarch when ISA level 3 or higher is enabled by default. When glibc is built with ISA level 2 enabled by default, only keep SSE4.1 variant. Fixes BZ 31335. NB: elf/tst-valgrind-smoke test fails with ISA level 4, because valgrind doesn't support AVX512 instructions: https://bugs.kde.org/show_bug.cgi?id=383010 Reviewed-by: H.J.

The __exp1 internal symbol is no longer necessary. There is separate code path when fma is not available but the worst case error is about 0.54 ULP in both cases. The lookup table and consts for log are 4168 bytes. The .rodata+.text is decreased by 37908 bytes on aarch64. The non-nearest rounding error is less than 1 ULP.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the slow paths from pow. Like several other double precision math functions, pow is exactly rounded. This is not required from math functions and causes major overheads as it requires multiple fallbacks using higher precision arithmetic if a result is close to 0.5ULP. Ridiculous slowdowns of up to 100000x have been reported when the highest precision path triggers. All GLIBC math tests pass on AArch64 and x64 (with ULP of pow set to 1). The worst case error is ~0.506ULP. A simple test over a few hundred million values shows pow is 10% faster on average. This fixes BZ #13932.

They will also be active for ieee754 versions of ccos, ccosh, cosh, csin, csinh, sinh, exp10, gamma, and erf. Typical performance gains is typically around 5x when measured on Sparc s7 for common values between exp(1) and exp(40). Using the glibc perf tests on sparc, sparc (nsec) x86 (nsec) old new old new max 17629 395 5173 144 min 399 54 15 13 mean 5317 200 1349 23 The extreme max times for the old (ieee754) exp are due to the multiprecision computation in the old algorithm when the true value is very near 0.5 ulp away from an value representable in double precision. The new algorithm does not take special measures for those cases. The current glibc exp perf tests overrepresent those values. Informal testing suggests approximately one in 200 cases might invoke the high cost computation. The performance advantage of the new algorithm for other values is still large but not as large as indicated by the chart above. Glibc correctness tests for exp() and expf() were run. Within the test suite 3 input values were found to cause 1 bit differences (ulp) when "FE_TONEAREST" rounding mode is set. No differences in exp() were seen for the tested values for the other rounding modes. Typical example: exp(-0x1.760cd2p+0) (-1.46113312244415283203125) new code: 2.31973271630014299393707e-01 0x1.db14cd799387ap-3 old code: 2.31973271630014271638132e-01 0x1.db14cd7993879p-3 exp = 2.31973271630014285508337 (high precision) Old delta: off by 0.49 ulp New delta: off by 0.51 ulp In addition, because ieee754_exp() is used by other routines, cexp() showed test results with very small imaginary input values where the imaginary portion of the result was off by 3 ulp when in upward rounding mode, but not in the other rounding modes. For x86, tgamma showed a few values where the ulp increased to 6 (max ulp for tgamma is 5). Sparc tgamma did not show these failures. I presume the tgamma differences are due to compiler optimization differences within the gamma function.The gamma function is known to be difficult to compute accurately. * sysdeps/ieee754/dbl-64/e_exp.c: Include <math-svid-compat.h> and <errno.h>.

* Fix x86_64 fma4 pow inappropriate contraction (bug 19003).Joseph Myers2015-09-241-1/+1
| | | | | | | | | | | | | | | | The x86_64 fma4 version of pow fails to disable contraction of operations other than those explicitly intended to use fma instructions, so resulting in large ulps errors on processors with fma4 instructions, as in bug 18104 (165ulp for the test added for that bug; error originally reported by "blaaa" on #glibc). This patch adds $(config-cflags-nofma) for e_pow-fma4.c, corresponding to the use for e_pow.c in sysdeps/ieee754/dbl-64/Makefile. Tested for x86_64 on a processor with fma4. [BZ #19003] * sysdeps/x86_64/fpu/multiarch/Makefile (CFLAGS-e_pow-fma4.c): Add $(config-cflags-nofma).
