--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- And the problem is similar to PR108605, most of IPA uses unsigned int as type for byte offsets and while some spots check for offsets while bit offsets are typically using HOST_WIDE_INT. So, some larger bit offsets can't be represented in unsigned int byte offset.
