#9246: GHC generates poor code for repeated uses of min/max --------------------------------------------+------------------------------ Reporter: arotenberg | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Windows | Architecture: x86_64 Type of failure: Runtime performance bug | (amd64) Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: #6135 --------------------------------------------+------------------------------ Comment (by simonpj): Yes, let-no-escape should be better documented. And I feel bad that although it's terribly important for performance, it's entirely implicit in Core, and it's not hard for a transformation to inadvertently lose the LNE property. I'd like it to be more explicit, somehow. Simon -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9246#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
