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/pr30137-1.c | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr30137-1.c (limited to 'gcc/testsuite/gcc.dg/pr30137-1.c') diff --git a/gcc/testsuite/gcc.dg/pr30137-1.c b/gcc/testsuite/gcc.dg/pr30137-1.c new file mode 100644 index 000000000..cf1b40634 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr30137-1.c @@ -0,0 +1,23 @@ +/* { dg-do compile } */ +/* { dg-options "-w -fdump-tree-gimple" } */ + +/* Things that should not be folded. */ + +struct { long base; int tail; void * volatile ptr; } *s; +int foo3 (void) { return s == &s; } +int foo5 (void) { return s->ptr == s->ptr; } + +struct { union { int i; short s } u; } x; +int foo6 (void) { return x.u.i == x.u.s; } + +void **p; +int foo8 (void) { return p == &p; } +int foo9 (void) { return *p == p; } +int foo10 (void) { return *p == &p; } +int foo11 (void) { return p != &p; } +int foo12 (void) { return *p != p; } +int foo13 (void) { return *p != &p; } + +/* { dg-final { scan-tree-dump-not "= 0;" "gimple" } } */ +/* { dg-final { scan-tree-dump-not "= 1;" "gimple" } } */ +/* { dg-final { cleanup-tree-dump "gimple" } } */ -- cgit v1.2.3
