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/i386/funcspec-7.c | 13 +++++++++++++ 1 file changed, 13 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/funcspec-7.c (limited to 'gcc/testsuite/gcc.target/i386/funcspec-7.c') diff --git a/gcc/testsuite/gcc.target/i386/funcspec-7.c b/gcc/testsuite/gcc.target/i386/funcspec-7.c new file mode 100644 index 000000000..56b549050 --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/funcspec-7.c @@ -0,0 +1,13 @@ +/* Test whether using target specific options, we can generate the reciprocal + square root instruction. */ +/* { dg-do compile } */ +/* { dg-options "-O2 -march=k8 -mno-recip -mfpmath=sse -ffast-math" } */ + +float do_recip (float a) __attribute__((__target__("recip"))); +float do_normal (float a); + +float do_recip (float a) { return 1.0f / __builtin_sqrtf (a); } +float do_normal (float a) { return 1.0f / __builtin_sqrtf (a); } + +/* { dg-final { scan-assembler "sqrtss" } } */ +/* { dg-final { scan-assembler "rsqrtss" } } */ -- cgit v1.2.3
