--- Comment #7 from Jan Hubicka <hubicka at gcc dot gnu.org> --- Created attachment 33944 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33944&action=edit Changes in release_ssa dump These are changes made by tree-ssa-pre devirtualization (that triggers the regression alone). There are no changes in early inlining, just some indirect calls are replaced by direct. This should be always good idea - it seems that simply global inliner degenerates somehow.
