For some reason ghc-7.8 and earlier were firing extra rules when compiled with `-prof -auto-all`. {{{ module T9406 where class (Fractional a) => Norm a where norm :: a -> a normalize :: (Norm a) => a -> a normalize x = x / norm x }}} {{{ $ ghc-7.8.4 -c T9406.hs -fforce-recomp -O -ddump-rule-firings -auto-all -prof Rule fired: Class op $p1Norm Rule fired: Class op norm Rule fired: Class op / $ ghc-7.8.4 -c T9406.hs -fforce-recomp -O -ddump-rule-firings $ ghc-7.10.2 -c T9406.hs -fforce-recomp -O -ddump-rule-firings -auto-all -prof $ ghc-7.10.2 -c T9406.hs -fforce-recomp -O -ddump-rule-firings }}} I'm not adding this as a test, since we have T7837 already. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9406#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
