These days -O2, which invokes the SpecConstr pass, can have a big effect, but only on some programs.
it also enables -optc-O2. so, answering Neil's question: -O2 -funbox-strict-fields (sidenote to SPJ: -funbox-simple-strict-fields may be a good way to _safe_ optimization) RTS -A10m option may be helpful (even with 6.6), so you may allow to run program two times - with and without this option - and select the best run btw, writing this message i thought that -fconvert-strings-to-ByteStrings option will give a significant boost to many programs without rewriting them :) -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
