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/vector-2.c | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/vector-2.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/vector-2.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/vector-2.c b/gcc/testsuite/gcc.dg/tree-ssa/vector-2.c new file mode 100644 index 000000000..e34532d3f --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/vector-2.c @@ -0,0 +1,23 @@ +/* { dg-do compile } */ +/* { dg-options "-w -O1 -fdump-tree-optimized" } */ +/* { dg-options "-w -O1 -fdump-tree-optimized -msse" { target { i?86-*-* x86_64-*-* } } } */ + +#define vector __attribute__(( vector_size(16) )) + +float f(vector float a, int b, vector float c) +{ + vector float dd = c*a; + a = (vector float){0,0,0,0}; + c = (vector float){0,0,0,0}; + { + float d = ((float*)&a)[0]; + float d1 = ((float*)&c)[0]; + return d*d1; + } +} + +/* We should be able to optimize this to just "return 0.0;" */ +/* { dg-final { scan-tree-dump-times "BIT_FIELD_REF" 0 "optimized"} } */ +/* { dg-final { scan-tree-dump-times "0.0" 1 "optimized"} } */ + +/* { dg-final { cleanup-tree-dump "optimized" } } */ -- cgit v1.2.3
