--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> --- In particular, in ehcleanup1 it is the sink_clobbers optimization added for PR51117. I think it would be strongly preferrable to fix this in the FE, because if we'd need to change sink_clobbers, I'd be afraid we'd get significantly worse code generation with -flifetime-dse than before.
