--- Comment #4 from Kewen Lin <linkw at gcc dot gnu.org> ---
For test.c, even we are on ppc64le P9, it can also get ICE:

extern float *dest;
extern __vector_quad src;

int
foo ()
{
  __builtin_mma_disassemble_acc (dest, &src);
  return 0;
}


$ gcc test.c -mcpu=power10 -mno-vsx

test.c: In function ‘foo’:
test.c:14:1: error: insn does not satisfy its constraints:
