sparc: build with -mvis on sparc32/sparcv9 and sparc64 When building for sparc32/sparcv9 or sparc64, we assume that VIS instructions are available and use them in the sparc specific assembly code. However we do not tell GCC to use such instructions, resulting in slightly suboptimal code. Fix that by passing -Wa,-Av9a -mvis to GCC. Changelog: * sysdeps/sparc/sparc32/sparcv9/Makefile (sysdep-CFLAGS): Add -mvis. * sysdeps/sparc/sparc64/Makefile (sysdep-CFLAGS): New. Define to -Wa,-Av9a -mvis. 2016-08-05 20:35:01 +00:00			`sysdep-CFLAGS += -mcpu=ultrasparc -Wa,-Av9a -mvis`
Sparc merge from Jakub. 1999-04-14 Jakub Jelinek <jj@ultra.linux.cz> * scripts/config.sub: Allow sparcv[6789]-* and sparcv8plus{,a}-* architectures. * sysdeps/sparc/sparc32/sparcv8/Makefile: Use sysdep-CFLAGS instead of CFLAGS. * sysdeps/sparc/sparc32/sparcv8/Makefile: Use sysdep-CFLAGS instead of CFLAGS. For gnulib and string directories use -Wa,-Av9a gcc ASFLAGS. * sysdeps/sparc/sparc32/sparcv9/memmove.c: New file. * sysdeps/unix/sysv/linux/sparc/sparc32/dl-procinfo.h: New file. * sysdeps/unix/sysv/linux/sparc/sparc64/dl-procinfo.h: New file. * shlib-versions: Handle sparcv[6789]-* and sparcv8plus{,a}-* the same way as sparc-*. 1999-04-14 15:48:28 +00:00
Add framework for using sparc VIS3 instructions, use it for copysign/signbit. * sysdeps/sparc/configure.in: New file. * sysdeps/sparc/configure: Generate. * configure.in (libc_cv_sparc_as_vis3): Substitute. * configure: Regenerate. * config.h.in (HAVE_AS_VIS3_SUPPORT): New. * config.make.in (have-as-vis3): New. * sysdeps/sparc/sparc32/sparcv9/Makefile (ASFLAGS-): If VIS3 is available use -Av9d instead of -Av9a. sysdeps/sparc/sparc64/Makefile: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile: New file. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_copysign-vis3.S: New file. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_copysign.S: New file. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_copysignf-vis3.S: New file. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_copysignf.S: New file. * sysdeps/sparc/sparc64/fpu/multiarch/Makefile: New file. * sysdeps/sparc/sparc64/fpu/multiarch/s_signbit-vis3.S: New file. * sysdeps/sparc/sparc64/fpu/multiarch/s_signbit.S: New file. * sysdeps/sparc/sparc64/fpu/multiarch/s_signbitf-vis3.S: New file. * sysdeps/sparc/sparc64/fpu/multiarch/s_signbitf.S: New file. 2012-03-14 23:29:47 +00:00			`ASFLAGS-.o += -Wa,-Av9d`
