            Bug ID: 109117
           Summary: "__builtin_ia32_vaesdec_v16qi" compiled only with
                    option -mvaes report ICE.
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: lin1.hu at intel dot com
  Target Milestone: ---

When the compiler compiles "__builtin_ia32_vaesdec_v16qi" with option
-mvaes,-no-avx512vl, it reports ICE.

The detail can refer to https://godbolt.org/z/fEGavbGWz.

Test-case:

typedef char __v16qi __attribute__ ((__vector_size__(16)));
typedef long long __m128i __attribute__((__vector_size__(16),
__aligned__(16)));
volatile __v16qi x, y;
volatile __m128i res;

void
foo (void)
{
    res =3D (__m128i) __builtin_ia32_vaesdec_v16qi (x, y);
