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.dg/pr15784-3.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr15784-3.c (limited to 'gcc/testsuite/gcc.dg/pr15784-3.c') diff --git a/gcc/testsuite/gcc.dg/pr15784-3.c b/gcc/testsuite/gcc.dg/pr15784-3.c new file mode 100644 index 000000000..746f9660e --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr15784-3.c @@ -0,0 +1,14 @@ +/* { dg-do compile } */ +/* { dg-skip-if "No NaN support" { spu-*-* } } */ +/* SH4 without -mieee defaults to -ffinite-math-only. */ +/* { dg-options "-fdump-tree-gimple -fno-finite-math-only" } */ +/* Test for folding abs(x) where appropriate. */ +#define abs(x) x > 0 ? x : -x +extern double fabs (double); + +int a (float x) { + return fabs(x) >= 0.0; +} + +/* { dg-final { scan-tree-dump-times "ABS_EXPR" 1 "gimple" } } */ +/* { dg-final { cleanup-tree-dump "gimple" } } */ -- cgit v1.2.3
