[Bug target/43667] New: ICE with __builtin_ia32_vpermil2p* and -mavx

[jakub at gcc dot gnu dot org]

typedef double __v2df __attribute__ ((__vector_size__ (16)));
typedef long long __v2di __attribute__ ((__vector_size__ (16)));

__v2df
foo (__v2df X, __v2df Y, __v2di C)
{
  return __builtin_ia32_vpermil2pd (X, Y, C, 1);
}
-O2 -mavx results in:
/usr/src/gcc/obj/gcc/a.c: In function 'foo':
/usr/src/gcc/obj/gcc/a.c:8:1: error: unrecognizable insn:
