#8871: No-op assignment I64[BaseReg + 784] = I64[BaseReg + 784]; is generated into optimized Cmm -------------------------------------+------------------------------------ Reporter: kgardas | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.9 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: Other | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by simonmar): Yes, this is just a missing optimisation. I didn't implement it because I hadn't seen any code that needed it, until now. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8871#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
