#8598: IO hack in demand analyzer gets in the way of CPR -------------------------------------+------------------------------------- Reporter: nomeata | Owner: (none) Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: T8598 Blocked By: | Blocking: Related Tickets: #1600 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): For pure ccalls like this one we have no business messing with IO at all. I'd love to implement the first bullet of comment:2. What you say may also be true of tail-recursive functions that ''do'' perform IO, but there would be fewer cases where it mattered. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8598#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
