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/20030714-2.c | 39 ++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/20030714-2.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/20030714-2.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/20030714-2.c b/gcc/testsuite/gcc.dg/tree-ssa/20030714-2.c new file mode 100644 index 000000000..cac648687 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/20030714-2.c @@ -0,0 +1,39 @@ +/* { dg-do compile } */ +/* { dg-options "-O1 -fdump-tree-dom2" } */ + + +union tree_node; +typedef union tree_node *tree; +extern const char tree_code_type[]; +struct tree_common +{ + int code; + tree type; +}; +struct tree_exp +{ + tree operands[1]; +}; +union tree_node +{ + struct tree_common common; + struct tree_exp exp; +}; +long +get_alias_set (t) + tree t; +{ + if (tree_code_type[t->common.code] != 't' && t->common.type == 0) + return 0; + if (tree_code_type[t->common.code] != 't') + { + while (t->exp.operands[0]) + t = t->exp.operands[0]; + } +} + +/* There should be exactly three IF conditionals if we thread jumps + properly. */ +/* { dg-final { scan-tree-dump-times "if " 3 "dom2"} } */ + +/* { dg-final { cleanup-tree-dump "dom2" } } */ -- cgit v1.2.3
