sparc64 passes floating point values in the floating point registers. As the the generic ceil, floor and trunc functions use integer instructions, it makes sense to provide a VIS3 version consisting in the the generic version compiled with -mvis3. GCC will then use movdtox, movxtod, movwtos and movstow instructions. sparc32 passes the floating point values in the integer registers, so it doesn't make sense to do the same. Changelog: * sysdeps/ieee754/dbl-64/s_trunc.c: Avoid alias renamed. * sysdeps/ieee754/dbl-64/wordsize-64/s_trunc.c: Likewise. * sysdeps/ieee754/flt-32/s_truncf.c: Likewise. * sysdeps/sparc/sparc64/fpu/multiarch/Makefile [$(subdir) = math && $(have-as-vis3) = yes] (libm-sysdep_routines): Add s_ceilf-vis3, s_ceil-vis3, s_floorf-vis3, s_floor-vis3, s_truncf-vis3, s_trunc-vis3. (CFLAGS-s_ceilf-vis3.c): New. Set to -Wa,-Av9d -mvis3. (CFLAGS-s_ceil-vis3.c): Likewise. (CFLAGS-s_floorf-vis3.c): Likewise. (CFLAGS-s_floor-vis3.c): Likewise. (CFLAGS-s_truncf-vis3.c): Likewise.
