...ot arguing] My guess: b/c we don`t want programs to give different results when compiled at different "-O<...>" settings with the exception of "-Ofast". At any rate, the above change is trivial to apply to my recent proposed patch: just remove the "&& (Res.getCodeGenOpts().OptimizationLevel >= 3)" part of the condition. Regards, Abe
