#8275: Loopification breaks profiling ----------------------------------------+---------------------------------- Reporter: jstolarek | Owner: jstolarek Type: bug | Status: new Priority: high | Milestone: 7.8.1 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: 8456 | Related Tickets: ----------------------------------------+---------------------------------- Comment (by simonpj): It's absolutely right to refer to `(old+0)`. But I don't understand the patch (in comment 19), to `CmmLayoutStack`. The change made there is simply to ''pass a different (larger) value to `manifestSp`''. And that's the only change to that module. So we'll generate different, wrong code. I don't see how this can possibly work. And yet apparently it does. What am I missing? (The change to `StgCmmHeap` is different, and is fine.) Simon -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8275#comment:24 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
