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/tree-ssa/pr21582.c | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/pr21582.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/pr21582.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/pr21582.c b/gcc/testsuite/gcc.dg/tree-ssa/pr21582.c new file mode 100644 index 000000000..0f5dc9ec1 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/pr21582.c @@ -0,0 +1,28 @@ +/* { dg-do link } */ +/* { dg-options "-O2 -fdump-tree-vrp1" } */ + +static inline void do_thing(char *s, int *p, char *q) +{ + /* This should be folded away. */ + if (s == 0 || q == 0) + link_error (); + + /* This should not be folded as 'p' is not marked nonnull. */ + if (p) + *p = 3; +} + +void __attribute__((nonnull (1, 3))) do_other_thing(char *s, int *p, char *q) +{ + do_thing(s, p, q); +} + +int i; + +main() +{ + do_other_thing ("xxx", &i, "yyy"); +} + +/* { dg-final { scan-tree-dump-times "Folding predicate p_.*" 0 "vrp1" } } */ +/* { dg-final { cleanup-tree-dump "vrp1" } } */ -- cgit v1.2.3
