#8457: -ffull-laziness does more harm than good -------------------------------------+------------------------------------ Reporter: errge | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.10.1 Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Changes (by simonpj): * cc: bos@…, johan.tibell@… (added) Comment: Thanks. A couple of `nofib` programs get a lot worse (eg `partsof` allocates 20x more), and the geometric mean of allocation I speculate that some of these extreme effects are because the programs have static data, but I'm not sure. The question is whether "typical" GHC users will see things getting better or worse. I'd be happy to know what our GHC Performance Tsars think (or indeed anyone else). Bryan, Johan: any views?
