* powerpc: Add a POWER8-optimized version of expf()Tulio Magno Quites Machado Filho2016-06-301-0/+2
| | | | | | | | This implementation is based on the one already used at sysdeps/x86_64/fpu/e_expf.S. This implementation improves the performance by ~14% on average in synthetic benchmarks at the cost of decreasing accuracy to 1 ULP.

* PowerPC: Fix nearbyint/nearbyintf result for FE_DOWNWARDAdhemerval Zanella2014-04-061-0/+192
| | | | | | | | | This patch fixes the powerpc32 optimized nearbyint/nearbyintf bogus results for FE_DOWNWARD rounding mode. This is due wrong instructions sequence used in the rounding calculation (two subtractions instead of adition and a subtraction). Fixes BZ#16815.

* Don't include individual test ulps in libm-test-ulps.Joseph Myers2014-03-051-19556/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As recently discussed <https://sourceware.org/ml/libc-alpha/2014-02/msg00670.html>, it doesn't seem particularly useful for libm-test-ulps files to contain huge amounts of data on ulps for individual tests; just the global maximum observed ulps for each function, together with the verification of exceptions, errno and special results such as infinities and NaNs for each test, suffices to verify that a function's behavior on the given test inputs is within the expected accuracy. Removing this data reduces source tree churn caused by updates to these files when libm tests are added, and reduces the frequency with which testsuite additions actually need libm-test-ulps changes at all. Accordingly, this patch removes that data, so that individual tests get checked against the global bounds for the given function and only generate an error if those are exceeded. Tested x86_64 (including verifying that if an ulps value is artificially reduced, the tests do indeed fail as they should and "make regen-ulps" generates the expected changes). * math/libm-test.inc (struct ulp_data): Don't refer to ulps for individual tests in comment.

(check_complex): Update calls to check_float_internal. (START): Pass argument to init_max_error. * math/gen-libm-test.pl (%results): Don't include "kind" information.

* PowerPC floating point little-endian [3 of 15]Alan Modra2013-10-041-0/+3

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.
