--- Comment #19 from Richard Biener <rguenth at gcc dot gnu.org> --- Compiling insn-emit.ii on a x86_64 host with a 13.2 release compiler shows most time is spent in inlining and CFG cleanup (the latter possibly in functions with a very large number of conditionals). For CCP it's interesting that most of the time is spent in ccp_finalize (doing the substitute_and_fold step). That engine was made more and more complicated (instead of getting rid of it ...).
