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/pure-1.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pure-1.c (limited to 'gcc/testsuite/gcc.dg/pure-1.c') diff --git a/gcc/testsuite/gcc.dg/pure-1.c b/gcc/testsuite/gcc.dg/pure-1.c new file mode 100644 index 000000000..f365c8dae --- /dev/null +++ b/gcc/testsuite/gcc.dg/pure-1.c @@ -0,0 +1,16 @@ +/* Regression test for PR middle-end/23584 */ +/* Verify that dereferencing a volatile element in a struct causes + the function not be pure. */ + +/* { dg-do compile } */ +/* { dg-options "-O1 -fdump-ipa-pure-const" } */ + +struct test_a { volatile int a; }; + +int func_a(struct test_a *a) +{ + return a->a; +} + +/* { dg-final { scan-ipa-dump-not "found to be pure: func_a" "pure-const" } } */ +/* { dg-final { cleanup-ipa-dump "pure-const" } } */ -- cgit v1.2.3
