2019-05-09powerpc: round/roundf refactorAdhemerval Zanella
This patches consolidates all the powerpc round{f} implementations on the generic sysdeps/powerpc/fpu/s_round{f}. The generic implementation uses either the compiler builts for ISA 2.03+ (which generates the frim instruction) or a generic implementation which uses FP only operations. The IFUNC organization for powerpc64 is also change to be enabled only for powerpc64 and not for powerpc64le (since minium ISA of 2.08 does not require the fallback generic implementation). Checked on powerpc-linux-gnu (built without --with-cpu, with --with-cpu=power4 and with --with-cpu=power5+ and --disable-multi-arch), powerpc64-linux-gnu (built without --with-cp and with --with-cpu=power5+ and --disable-multi-arch). * sysdeps/powerpc/fpu/round_to_integer.h (set_fenv_mode): Add ROUND handling.

Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch makes powerpc libm function implementations use libm_alias_float to define function aliases.

2016-05-27Fix powerpc32 ceil, rint etc. on sNaN input (bug 20160).Joseph Myers
The powerpc32 versions of ceil, floor, round, trunc, rint, nearbyint and their float versions return sNaN for sNaN input when they should return qNaN. This patch fixes them to add a NaN argument to itself to quiet sNaNs before returning. The powerpc64 versions, which have the same bug, will be addressed separately. Tested for powerpc32.

2015-11-12Fix powerpc round, roundf spurious "inexact" (bug 19238).Joseph Myers
The powerpc hard-float round and roundf functions, both 32-bit and 64-bit, raise spurious "inexact" exceptions for integer arguments from adding 0.5 and rounding to integer toward zero. Since these functions already save and restore the rounding mode, it's natural to make them restore the full floating-point state instead to fix this bug, which this patch does. The save of the state is moved after the first floating-point operation on the input so that any "invalid" exceptions from signaling NaN inputs are properly preserved. As a consequence of this approach to the fix, "inexact" for noninteger arguments (disallowed by TS 18661-1 but not by C99/C11, see bug 15479) is also avoided for these implementations; this is *not* a general fix for bug 15479 since plenty of other implementations of various functions still raise spurious "inexact" for noninteger arguments. This issue and fix do not apply to builds using power5+ versions of round and roundf, which use the frin instruction and avoid "inexact" exceptions that way. This patch should get hard-float powerpc32 and powerpc64 (default function implementations) back to a state where test-float and test-double will pass after ulps regeneration. Tested for powerpc32 and powerpc64. [BZ #15479] [BZ #19238] * sysdeps/powerpc/powerpc32/fpu/s_round.S (__round): Save floating-point state after first operation on input.
