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/20030728-1.c | 47 ++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/20030728-1.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/20030728-1.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/20030728-1.c b/gcc/testsuite/gcc.dg/tree-ssa/20030728-1.c new file mode 100644 index 000000000..f884736a1 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/20030728-1.c @@ -0,0 +1,47 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-rtl-expand-details" } */ + + +union tree_node; +typedef union tree_node *tree; + +enum tree_code +{ + ARRAY_TYPE, + LAST_AND_UNUSED_TREE_CODE +}; + +struct tree_common +{ + enum tree_code code:8; +}; + + + + + +union tree_node +{ + struct tree_common common; +}; + + + + +int +objects_must_conflict_p (t1, t2) + tree t1, t2; +{ + + if ((t1->common.code == ARRAY_TYPE) != (t2 + && t2->common.code == ARRAY_TYPE)) + return 11; + + + return foo (t2 ? get_alias_set (t2) : 0); +} + +/* There should be two assignments of variables to the value zero. */ +/* { dg-final { scan-rtl-dump-times "PART.. = 0" 2 "expand"} } */ + +/* { dg-final { cleanup-rtl-dump "expand" } } */ -- cgit v1.2.3
