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/fold-overflow-1.c | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/fold-overflow-1.c (limited to 'gcc/testsuite/gcc.dg/fold-overflow-1.c') diff --git a/gcc/testsuite/gcc.dg/fold-overflow-1.c b/gcc/testsuite/gcc.dg/fold-overflow-1.c new file mode 100644 index 000000000..8fddc9fc0 --- /dev/null +++ b/gcc/testsuite/gcc.dg/fold-overflow-1.c @@ -0,0 +1,23 @@ +/* { dg-do compile } */ +/* { dg-skip-if "consts are shorts, not longs" { "m32c-*-*" "avr-*-*" } { "*" } { "" } } */ +/* { dg-skip-if "No Inf support" { spu-*-* } } */ +/* { dg-options "-O -ftrapping-math" } */ + +/* There should be exactly 2 +Inf in the assembly file. */ + +float f1 = __FLT_MAX__ + __FLT_MAX__; + +float foo1(void) +{ + return __FLT_MAX__ + __FLT_MAX__; +} + +float f2 = 1.0f/0.0f; + +float foo2(void) +{ + return 1.0f/0.0f; +} + +/* { dg-final { scan-assembler-times "2139095040" 2 { target { ! mmix-*-* } } } } */ +/* { dg-final { scan-assembler-times "#7f800000" 2 { target mmix-*-* } } } */ -- cgit v1.2.3
