Bug ID: 84999
Summary: [7/8 Regression] ICE in make_vector_type, at
tree.c:9561
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Changed before 20171019, ICEs with option -m32 :
$ cat z1.c
void
foo (void)
{
__attribute__ ((__vector_size__ (4 * sizeof (unsigned)))) __float128 a;
0 != a;
}
$ gcc-7-20170226 -c z1.c -m64
$ gcc-7-20170226 -c z1.c -m32
$
$ gcc-8-20180318 -c z1.c -m64
$ gcc-8-20180318 -c z1.c -m32
