#6087: Join points need strictness analysis -------------------------------------+------------------------------------- Reporter: simonpj | Owner: (none) Type: bug | Status: infoneeded Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 7.4.1 Resolution: | Keywords: JoinPoints Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Interesting. * These are `-O` vs `-O + late-dmd-anal` I assume. It'd be worth doing the same with `-O2` vis `-O2 + late-dmd-anal` * Did you recompile all the libraries, or just nofib? * A 4.6% increase in compiler allocations and compile time. * We get some small wins. * Can you see what is happening with the 5% allocation increase in `mate`? * I think that HEAD has indeed abandoned the "clever .hi file scheme", so we don't need to worry about that part. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/6087#comment:20 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
