From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/gcc.target/powerpc/recip-2.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 gcc/testsuite/gcc.target/powerpc/recip-2.c (limited to 'gcc/testsuite/gcc.target/powerpc/recip-2.c') diff --git a/gcc/testsuite/gcc.target/powerpc/recip-2.c b/gcc/testsuite/gcc.target/powerpc/recip-2.c new file mode 100644 index 000000000..3e64c0757 --- /dev/null +++ b/gcc/testsuite/gcc.target/powerpc/recip-2.c @@ -0,0 +1,21 @@ +/* { dg-do compile { target { { powerpc*-*-* } && { ! powerpc*-apple-darwin* } } } } */ +/* { dg-options "-O2 -mrecip -ffast-math -mcpu=power5" } */ +/* { dg-final { scan-assembler-times "frsqrtes" 1 } } */ +/* { dg-final { scan-assembler-times "fmsubs" 1 } } */ +/* { dg-final { scan-assembler-times "fmuls" 6 } } */ +/* { dg-final { scan-assembler-times "fnmsubs" 3 } } */ +/* { dg-final { scan-assembler-times "fsqrt" 1 } } */ + +/* power5 resqrte is not accurate enough, and should not be generated by + default for -mrecip. */ +double +rsqrt_d (double a) +{ + return 1.0 / __builtin_sqrt (a); +} + +float +rsqrt_f (float a) +{ + return 1.0f / __builtin_sqrtf (a); +} -- cgit v1.2.3
