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/20030730-1.c | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/20030730-1.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/20030730-1.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/20030730-1.c b/gcc/testsuite/gcc.dg/tree-ssa/20030730-1.c new file mode 100644 index 000000000..bb474ff4b --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/20030730-1.c @@ -0,0 +1,25 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-dom2" } */ + +extern void exit (int); +extern void *ggc_alloc (__SIZE_TYPE__); +typedef struct dw_attr_struct *dw_attr_ref; +typedef struct dw_attr_struct +{ + int dw_attr; +} +dw_attr_node; +void +foo (int attr_kind, unsigned long offset) +{ + dw_attr_ref attr = (dw_attr_ref) ggc_alloc (sizeof (dw_attr_node)); + attr->dw_attr = attr_kind; + if (attr != 0) + exit (0); +} + +/* There should be no IF conditionals, unless target has fno-delete-null-pointer-checks */ +/* { dg-final { scan-tree-dump-times "if " 0 "dom2" { target { ! keeps_null_pointer_checks } } } } */ +/* { dg-final { scan-tree-dump "if " "dom2" { target { keeps_null_pointer_checks } } } } */ + +/* { dg-final { cleanup-tree-dump "dom2" } } */ -- cgit v1.2.3
