*	Use trunc functions not __trunc functions in glibc libm.	Joseph Myers	2018-09-20	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Continuing the move to use, within libm, public names for libm functions that can be inlined as built-in functions on many architectures, this patch moves calls to __trunc functions to call the corresponding trunc names instead, with asm redirection to __trunc when the calls are not inlined. Tested for x86_64, and with build-many-glibcs.py. * include/math.h [!_ISOMAC && !(__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0) && !NO_MATH_REDIRECT] (trunc): Redirect using MATH_REDIRECT. * sysdeps/aarch64/fpu/s_trunc.c: Define NO_MATH_REDIRECT before header inclusion. * sysdeps/aarch64/fpu/s_truncf.c: Likewise. * sysdeps/ieee754/dbl-64/wordsize-64/s_trunc.c: Likewise. * sysdeps/ieee754/float128/s_truncf128.c: Likewise. * sysdeps/ieee754/dbl-64/s_trunc.c: Likewise. * sysdeps/ieee754/flt-32/s_truncf.c: Likewise. * sysdeps/ieee754/ldbl-128/s_truncl.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_trunc.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_truncf.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_trunc.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_truncf.c: Likewise. * sysdeps/riscv/rv64/rvd/s_trunc.c: Likewise. * sysdeps/riscv/rvf/s_truncf.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_trunc.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/s_truncf.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_trunc.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_truncf.c: Likewise. * sysdeps/m68k/m680x0/fpu/s_trunc_template.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_truncl.c: Likewise.

*	Use libm_alias_double for x86_64.	Joseph Myers	2017-11-29	1	-1/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch makes x86_64 libm function implementations use libm_alias_double to define function aliases. Tested with the glibc testsuite for x86_64, and tested with build-many-glibcs.py for all its x86_64 configurations that installed stripped shared libraries are unchanged by the patch. * sysdeps/x86_64/fpu/multiarch/s_atan.c: Include <libm-alias-double.h>.

*	Add SSE4.1 trunc, truncf (bug 20142).	Joseph Myers	2017-09-20	1	-0/+29
	This patch adds SSE4.1 versions of trunc and truncf, using the roundsd / roundss instructions, similar to the versions of ceil, floor, rint and nearbyint functions we already have. In my testing with the glibc benchtests these are about 30% faster than the C versions for double, 20% faster for float. Tested for x86_64. [BZ #20142] * sysdeps/x86_64/fpu/multiarch/Makefile (libm-sysdep_routines): Add s_trunc-c, s_truncf-c, s_trunc-sse4_1 and s_truncf-sse4_1. * sysdeps/x86_64/fpu/multiarch/s_trunc-c.c: New file. * sysdeps/x86_64/fpu/multiarch/s_trunc-sse4_1.S: Likewise. * sysdeps/x86_64/fpu/multiarch/s_trunc.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_truncf-c.c: Likewise. * sysdeps/x86_64/fpu/multiarch/s_truncf-sse4_1.S: Likewise. * sysdeps/x86_64/fpu/multiarch/s_truncf.c: Likewise.
