#13104: runRW# ruins join points -------------------------------------+------------------------------------- Reporter: lukemaurer | Owner: Type: bug | Status: new Priority: normal | Milestone: 8.4.1 Component: Compiler | Version: 8.1 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): Cool idea though. See `Note [runRW magic]` in `MkId` for the main comment on this. I like the way that consumers correctly consume the result. We'd really like that NOINLINE to disapper right at the end somehow. One thing I like about `runRW#` is that it signals the magic very clearly; somehow a NOINLINE on a join point feels a bit too subtle. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13104#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
