#3629: Code compiled WITHOUT profiling many times slower than compiled WITH profiling on ---------------------------------+------------------------------------------ Reporter: gchrupala | Owner: Type: bug | Status: new Priority: normal | Milestone: 6.12 branch Component: Compiler | Version: 6.13 Keywords: | Difficulty: Unknown Os: Unknown/Multiple | Testcase: Architecture: Unknown/Multiple | Failure: None/Unknown ---------------------------------+------------------------------------------
Comment(by simonmar): We suggest trying the following (with both 6.10.4 and 6.13) to see if they make any difference: * `-fno-state-hack` (see #1168) * `-fno-cse` * `-fno-full-laziness` all 3 of these "optimizations" can introduce slowdowns as well as speedups, so it may be that this program is an example of that. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/3629#comment:6> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
