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/pr39431.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/pr39431.c (limited to 'gcc/testsuite/gcc.target/i386/pr39431.c') diff --git a/gcc/testsuite/gcc.target/i386/pr39431.c b/gcc/testsuite/gcc.target/i386/pr39431.c new file mode 100644 index 000000000..756bdb9eb --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/pr39431.c @@ -0,0 +1,15 @@ +/* PR target/39431 */ +/* { dg-do compile } */ +/* { dg-options "-O2" } */ +/* { dg-options "-O2 -march=i686 -fpic" { target { ilp32 && fpic } } } */ + +extern void bar (char *, int); + +int +foo (long long *p, long long oldv, long long *q, int n) +{ + char buf[n]; + bar (buf, n); + p[256 + n] = __sync_val_compare_and_swap (p + n, oldv, oldv + 6); + return __sync_bool_compare_and_swap (q + n, oldv, oldv + 8); +} -- cgit v1.2.3
