#10397: Compiler performance regression 7.6 -> 7.8 in elimCommonBlocks -------------------------------------+------------------------------------- Reporter: TobyGoodwin | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.4 Resolution: | Keywords: Operating System: Unknown/Multiple | performance Type of failure: None/Unknown | Architecture: Blocked By: | Unknown/Multiple Related Tickets: | Test Case: see ticket | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by rwbarton): The source is very small, but the simplifier blows things up quite a lot, even though I have not used any INLINE directives. That is probably worth a separate issue. However, even after that blow-up the Core program size is not so unreasonably large that it should take several minutes to compile. (That is it is unreasonably large for the specific source program which produced it, but not unreasonably large for a different, reasonably large source program.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10397#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
