Product: gcc
Version: 14.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3

Target Milestone: ---
The following crashes:
$ cat ice.c
typedef float v8sf __attribute__((vector_size(32)));
typedef int v8si __attribute__((vector_size(32)));
v8sf foo1 (v8sf x, v8sf y)
{
v8sf tem0 = x - y;
v8sf tem1 = x + y;
return __builtin_shuffle (tem0, tem1, (v8si) { 0, 9, 2, 11, 4, 13, 6, 15 });
}
$ gcc ice.c -O -c
