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/g++.dg/opt/float1.C | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 gcc/testsuite/g++.dg/opt/float1.C (limited to 'gcc/testsuite/g++.dg/opt/float1.C') diff --git a/gcc/testsuite/g++.dg/opt/float1.C b/gcc/testsuite/g++.dg/opt/float1.C new file mode 100644 index 000000000..8f26ed5c8 --- /dev/null +++ b/gcc/testsuite/g++.dg/opt/float1.C @@ -0,0 +1,21 @@ +// PR optimization/11637 +// Origin: + +// This used to fail to assemble on x86 because a decimal +// floating point litteral was emitted, which originated +// from a bogus REG_EQUAL note not removed by the combiner. + +// { dg-do assemble } +// { dg-options "-O2 -fnon-call-exceptions" } + +void f(long int seed); + +void g(float &o) +{ + float a = 0.05f; + float b = 1.0 - a; + float c = 1.0 + a; + + f(0); + o = a; +} -- cgit v1.2.3
