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/pr23848-2.c | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/pr23848-2.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/pr23848-2.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/pr23848-2.c b/gcc/testsuite/gcc.dg/tree-ssa/pr23848-2.c new file mode 100644 index 000000000..c9691469d --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/pr23848-2.c @@ -0,0 +1,25 @@ +/* PR middle-end/23848 */ +/* { dg-do compile } */ +/* { dg-options "-O2 -fdump-tree-optimized" } */ + +void bar (char *, char *, char *, char *, int); +void foo (int size) +{ + char temp[size]; + temp[size-1] = '\0'; + { + char temp2[size]; + { + char temp3[size]; + { + char temp4[size]; + bar (temp, temp2, temp3, temp4, size); + } + } + bar (temp, temp2, (char *) 0, (char *) 0, size); + } +} + +/* { dg-final { scan-tree-dump-times "__builtin_stack_save" 1 "optimized"} } */ +/* { dg-final { scan-tree-dump-times "__builtin_stack_restore" 1 "optimized"} } */ +/* { dg-final { cleanup-tree-dump "optimized" } } */ -- cgit v1.2.3
