#14737: Improve performance of Simplify.simplCast -------------------------------------+------------------------------------- Reporter: tdammers | Owner: (none) Type: bug | Status: patch Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: #11735 #14683 | Differential Rev(s): Phab:D4385 Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): Yes, I think Simon's comment:10 is correct. Try removing that. Note that Phab:D4395 currently removes the `piResultTy` from that case, but it's quite possible that the `eqType` call is what's taking up the time. You might also try removing the similar clause from `pushCoValArg`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14737#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
