I'm not sure what you mean here by "simplifier rules deleted". The "simple-optimization" pass doesn't consult any user-specified RULES or anything -- it just does a few substitutions, etc. I don't think there's a way to disable it. Indeed, it's necessary in order for RULES to work, as the simple-optimizer shuffles RULES' left-hand sides to enable matching to succeed later on. Richard
