#8275: Loopification breaks profiling ----------------------------------------+---------------------------------- Reporter: jstolarek | Owner: Type: bug | Status: new Priority: highest | Milestone: Component: Profiling | Version: 7.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Building GHC failed | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: 8298 | Blocked By: | Related Tickets: ----------------------------------------+---------------------------------- Comment (by jstolarek): I actually already implemented 1), but the implementation is only a proof- of-concept. It's available [https://github.com/jstolarek/ghc/commit/66d5598bc1163c32267c55670c579d93cce9... here], but it need testing, cleanup (we can just drop sp_high and use final_hwn instead and perhaps entry_args are not used anymore?) and improving `constantFoldMachOpM` in `CmmOpt`, so that `if ((Sp + 56) - 96 < SpLim) goto u4yi; else goto u4yh;` gets constant folded properly. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8275#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
