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/pr44136.c | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr44136.c (limited to 'gcc/testsuite/gcc.dg/pr44136.c') diff --git a/gcc/testsuite/gcc.dg/pr44136.c b/gcc/testsuite/gcc.dg/pr44136.c new file mode 100644 index 000000000..e053cf811 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr44136.c @@ -0,0 +1,27 @@ +/* PR debug/44136 */ +/* { dg-do compile } */ +/* { dg-options "-w -O2 -g" } */ +/* { dg-options "-w -Wno-psabi -O2 -g -mno-sse" { target { { i?86-*-* x86_64-*-* } && ilp32 } } } */ + +#define vector __attribute((vector_size(16))) +vector float a; + +float +foo (float b) +{ + vector float c = { 0, 0, 0, 0 }; + vector float d = { 0, 0, 0, 0 }; + d += c; + return ((float *)&c)[2]; +} + +float +bar (vector float a, int b, vector float c) +{ + vector float e = c * a; + a = (vector float) { 0, 0, 0, 0 }; + c = (vector float) { 0, 0, 0, 0 }; + float d = ((float *)&a)[0]; + float f = ((float *)&c)[0]; + return d * f; +} -- cgit v1.2.3
