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/loadpre10.c | 49 +++++++++++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/loadpre10.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/loadpre10.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/loadpre10.c b/gcc/testsuite/gcc.dg/tree-ssa/loadpre10.c new file mode 100644 index 000000000..4147a702a --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/loadpre10.c @@ -0,0 +1,49 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-pre-stats" } */ +struct tree_common +{ + int code; +}; +union tree_node +{ + struct tree_common common; +}; +typedef union tree_node *tree; + +extern tree test (tree, int, int); +extern tree foo (void); +extern void abort (void) __attribute__ ((__noreturn__)); + +/* Redundant loads of expr->common.code */ +tree +test (tree expr, int t, int D17630) +{ + int __i; + +L0: + if (expr->common.code != 142) goto L23; else goto L2; + +L2: + __i = 0; + goto L10; + +L10: + __i = __i + 1; + if (D17630 != __i) goto L8; else goto L19; + +L8: + if (t) goto L15; else goto L10; + +L15: + expr = foo (); + if (expr->common.code != 142) goto L23; else goto L0; + +L19: + abort (); + +L23: + return expr; +} +/* { dg-final { scan-tree-dump-times "Eliminated: 1" 1 "pre"} } */ +/* { dg-final { cleanup-tree-dump "pre" } } */ + -- cgit v1.2.3
