--- Comment #4 from Jeffrey Walton <noloader at gmail dot com> ---
Thanks, and sorry to waste your time with it.
Before I spin up another report that wastes a lot time, does this look like
another issue with me (likely), or an issue with GCC (unlikely):
internal compiler error: in expand_shift_1, at expmed.c:2318
result = (r1 != r2);
Here's a quick copy/paste of the relevant pieces. I'll do the minimal working
example if needed.
// Executed with a sig_handler guard
volatile bool result = true;
...
const poly64_t a1={1}, b1={2};
const poly64x2_t a2={1}, b2={2};
const poly128_t r1 = vmull_p64(a1, b1);
const poly128_t r2 = vmull_high_p64(a2, b2);
result = (r1 != r2);
