#481: Recompilation check fails for TH -------------------------------------+------------------------------------- Reporter: simonpj | Owner: simonmar Type: bug | Status: closed Priority: normal | Milestone: 7.2.1 Component: Template Haskell | Version: 6.4.1 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect result | Unknown/Multiple at runtime | Test Case: TH_recompile Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonmar): I don't think there's any perf impact, the stability check is already being done. The problem you're most likely seeing is that the recompilation check for TH is more conservative than we need in many cases, because the compiler doesn't know what your TH code depends on so it has to assume the worst. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/481#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
