--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 61136 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=61136&action=edit gcc15-pr119834.patch Untested patch (except on a short testcase with memset (ptr, 0, 17); to verify that *clrmem_short -> *xc_zero splitting still works). Without a reproducer it is hard to do more. Perhaps it is late combine that propagates the constant? Can you compile with additional -da (assuming you still hit the ICE) and attach all the *.[0-9]*r.* dumps?
