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/pr30643.c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr30643.c (limited to 'gcc/testsuite/gcc.dg/pr30643.c') diff --git a/gcc/testsuite/gcc.dg/pr30643.c b/gcc/testsuite/gcc.dg/pr30643.c new file mode 100644 index 000000000..67fe111a7 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr30643.c @@ -0,0 +1,26 @@ +/* { dg-do compile } */ +/* { dg-options "-O2" } */ +/* { dg-final { scan-assembler-not "undefined" } } */ + +/* Make sure we optimize all calls away. */ + +extern void undefined (void); +struct s { int a, b; }; +void bar (struct s *ps, int *p, int *__restrict__ rp, int *__restrict__ rq) +{ + ps->a = 0; + ps->b = 1; + if (ps->a != 0) + undefined (); + p[0] = 0; + p[1] = 1; + if (p[0] != 0) + undefined (); + rp[0] = 0; + rq[0] = 1; + if (rp[0] != 0) + undefined (); +} +int main (void) { + return 0; +} -- cgit v1.2.3
