From bf79a337ec86c2530edd26f4270f9688bf428ea2 Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Fri, 5 Aug 2016 22:35:01 +0200 Subject: sparc32/sparcv9: add a VIS3 version of fdim sparc32 passes floating point values in the integer registers. VIS3 instructions gives access to the movwtos instruction to directly transfer a value from an integer register to a floating point register. Therefore it makes sense to provide a VIS3 version consisting in the generic version compiled with -mvis3. Changelog: * math/s_fdim.c: Avoid alias renamed. * math/s_fdimf.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile [$(subdir) = math && $(have-as-vis3) = yes] (libm-sysdep_routines): Add s_fdimf-vis3, s_fdim-vis3. (CFLAGS-s_fdimf-vis3.c): New. Set to -Wa,-Av9d -mvis3. (CFLAGS-s_fdim-vis3.c): Likewise. sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fdim-vis3.c: New file. sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fdim.c: Likewise. --- .../sparc/sparc32/sparcv9/fpu/multiarch/Makefile | 5 +++- .../sparc32/sparcv9/fpu/multiarch/s_fdim-vis3.c | 23 ++++++++++++++++ .../sparc/sparc32/sparcv9/fpu/multiarch/s_fdim.c | 32 ++++++++++++++++++++++ .../sparc32/sparcv9/fpu/multiarch/s_fdimf-vis3.c | 23 ++++++++++++++++ .../sparc/sparc32/sparcv9/fpu/multiarch/s_fdimf.c | 32 ++++++++++++++++++++++ 5 files changed, 114 insertions(+), 1 deletion(-) create mode 100644 sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fdim-vis3.c create mode 100644 sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fdim.c create mode 100644 sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fdimf-vis3.c create mode 100644 sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fdimf.c (limited to 'sysdeps/sparc/sparc32/sparcv9') diff --git a/sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile b/sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile index 13d3c6d..4489b70 100644 --- a/sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile +++ b/sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile @@ -5,7 +5,10 @@ libm-sysdep_routines += m_copysignf-vis3 m_copysign-vis3 s_fabs-vis3 \ s_rintf-vis3 s_rint-vis3 w_sqrt-vis3 w_sqrtf-vis3 \ s_fminf-vis3 s_fmin-vis3 s_fmaxf-vis3 s_fmax-vis3 \ s_fmaf-vis3 s_fma-vis3 s_nearbyint-vis3 \ - s_nearbyintf-vis3 + s_nearbyintf-vis3 s_fdimf-vis3 s_fdim-vis3 sysdep_routines += s_copysignf-vis3 s_copysign-vis3 + +CFLAGS-s_fdimf-vis3.c += -Wa,-Av9d -mvis3 +CFLAGS-s_fdim-vis3.c += -Wa,-Av9d -mvis3 endif endif diff --git a/sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fdim-vis3.c b/sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fdim-vis3.c new file mode 100644 index 0000000..2973b49 --- /dev/null +++ b/sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fdim-vis3.c @@ -0,0 +1,23 @@ +/* Compute positive difference, sparc 32-bit+v9+vis3. + Copyright (C) 2016 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
