--- Comment #6 from Uroš Bizjak <ubizjak at gmail dot com> ---
Here is a bit simpler testcase:
--cut here--
typedef float __v4sf __attribute__((__vector_size__ (16)));
__v4sf
foo (__v4sf x)
{
return x + (__v4sf){ 2.3f, 2.3f, 2.3f, 2.3f };
}
--cut here--
"cc1 -O2" on x86_64 target will show the issue in _.combine dump.
