From 3a16dd780eeba60266d75e4a562536cc0785bc4e Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Wed, 20 Mar 2019 04:14:28 +0000 Subject: [PATCH] powerpc: fma using builtins This patch just refactor the assembly implementation to use compiler builtins instead. 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/s_fma.S: Remove file. * sysdeps/powerpc/fpu/s_fmaf.S: Likewise. * sysdeps/powerpc/fpu/s_fma.c: New file. * sysdeps/powerpc/fpu/s_fmaf.c: Likewise. --- ChangeLog | 5 +++++ sysdeps/powerpc/fpu/{s_fma.S => s_fma.c} | 12 +++++------- sysdeps/powerpc/fpu/{s_fmaf.S => s_fmaf.c} | 12 +++++------- 3 files changed, 15 insertions(+), 14 deletions(-) rename sysdeps/powerpc/fpu/{s_fma.S => s_fma.c} (82%) rename sysdeps/powerpc/fpu/{s_fmaf.S => s_fmaf.c} (82%) diff --git a/ChangeLog b/ChangeLog index a4eb322b1d7..8a852d903d0 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,5 +1,10 @@ 2019-04-17 Adhemerval Zanella + * sysdeps/powerpc/fpu/s_fma.S: Remove file. + * sysdeps/powerpc/fpu/s_fmaf.S: Likewise. + * sysdeps/powerpc/fpu/s_fma.c: New file. + * sysdeps/powerpc/fpu/s_fmaf.c: Likewise. + * sysdeps/powerpc/fpu/s_fabs.S: Remove file. * sysdeps/powerpc/fpu/s_fabsf.S: Likewise. diff --git a/sysdeps/powerpc/fpu/s_fma.S b/sysdeps/powerpc/fpu/s_fma.c similarity index 82% rename from sysdeps/powerpc/fpu/s_fma.S rename to sysdeps/powerpc/fpu/s_fma.c index 92e08eb5835..688f9badf51 100644 --- a/sysdeps/powerpc/fpu/s_fma.S +++ b/sysdeps/powerpc/fpu/s_fma.c @@ -1,5 +1,5 @@ /* Compute x * y + z as ternary operation.
