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/ssa-ccp-18.c | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/ssa-ccp-18.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/ssa-ccp-18.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/ssa-ccp-18.c b/gcc/testsuite/gcc.dg/tree-ssa/ssa-ccp-18.c new file mode 100644 index 000000000..cbe12598b --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/ssa-ccp-18.c @@ -0,0 +1,20 @@ +/* { dg-do compile } */ +/* { dg-options "-O -fdump-tree-ccp1" } */ + +/* Check that we constant propagate &&c into the goto and remove + the unreachable BBs. */ + +void a(int*); void b(int*); void c(int*); void d(int*); +void func2(int* val) +{ + const void *const labels[] = { &&a, &&b, &&c, &&d }; + goto *labels[2]; + a: a(val); + b: b(val); + c: c(val); + d: d(val); +} + +/* { dg-final { scan-tree-dump-not "a \\\(" "ccp1" } } */ +/* { dg-final { scan-tree-dump-not "b \\\(" "ccp1" } } */ +/* { dg-final { cleanup-tree-dump "ccp1" } } */ -- cgit v1.2.3
