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/torture/pr37421.C | 39 ++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 gcc/testsuite/g++.dg/torture/pr37421.C (limited to 'gcc/testsuite/g++.dg/torture/pr37421.C') diff --git a/gcc/testsuite/g++.dg/torture/pr37421.C b/gcc/testsuite/g++.dg/torture/pr37421.C new file mode 100644 index 000000000..4b8447eac --- /dev/null +++ b/gcc/testsuite/g++.dg/torture/pr37421.C @@ -0,0 +1,39 @@ +/* { dg-do compile } */ + +#include +#include + +inline int +bci (const float &source) +{ + int dest; + memcpy (&dest, &source, sizeof (dest)); + return dest; +} + +inline float +bcf (const int &source) +{ + float dest; + memcpy (&dest, &source, sizeof (dest)); + return dest; +} + +float +Foo () +{ + const int foo = bci (0.0f); + int bar = foo; + const int baz = foo & 1; + if (!baz && (foo & 2)) + bar = 0; + return bcf (bar); +} + +int +main () +{ + printf ("Foo() = %f\n", Foo()); + return 0; +} + -- cgit v1.2.3
