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/pr48237.c | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/pr48237.c (limited to 'gcc/testsuite/gcc.target/i386/pr48237.c') diff --git a/gcc/testsuite/gcc.target/i386/pr48237.c b/gcc/testsuite/gcc.target/i386/pr48237.c new file mode 100644 index 000000000..e20446eab --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/pr48237.c @@ -0,0 +1,22 @@ +/* { dg-do compile } */ +/* { dg-options "-O -fcaller-saves -fschedule-insns2 -fselective-scheduling2 -mtune=core2" } */ + +union double_union +{ + double d; + int i[2]; +}; + +void bar (int, ...); + +void +foo (double d) +{ + union double_union du = { d }; + while (1) + { + du.i[1] -= 0x100000L; + bar (0, du.d); + du.d += d; + } +} -- cgit v1.2.3
