           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED

ICEs when compiling the following testcase, extracted from
gcc/testsuite/gcc.target/i386/sse2-pr94680.c, w/ -maltivec:

typedef long long v2di __attribute__((vector_size(16)));

v2di

{
  return __builtin_shuffle ((v2di) { 0, 0 }, x, (v2di) {3, 0});
}
