--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
If it would be just because of these 3-4 builtins/internal calls, then it is
not worth it IMHO, making a copy would increase compiler memory footprint.
Already from the earlier phases there are some ubsan builtins in there anyway
(shift instrumentation e.g.).
