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/20030814-4.c | 43 ++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/20030814-4.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/20030814-4.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/20030814-4.c b/gcc/testsuite/gcc.dg/tree-ssa/20030814-4.c new file mode 100644 index 000000000..2c2142cbc --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/20030814-4.c @@ -0,0 +1,43 @@ +/* { dg-do compile } */ +/* { dg-options "-O1 -fdump-tree-dom2 -fdump-tree-optimized" } */ + +extern void abort (void); +union tree_node; +typedef union tree_node *tree; +extern const char tree_code_type[]; +struct tree_common +{ + int code; +}; +struct tree_decl +{ + long pointer_alias_set; +}; +union tree_node +{ + struct tree_common common; + struct tree_decl decl; +}; +long +blah (decl, set) + tree decl; + long set; +{ + decl->decl.pointer_alias_set = set; + if (tree_code_type[decl->common.code] != 'd') + abort (); + record_alias_subset (decl->decl.pointer_alias_set); + if (set != -1) + set = 0; + return set; +} + +/* There should be precisely one reference to pointer_alias_set.
