#10521: Wrong results in strict Word8 storage on x64 -------------------------------------+------------------------------------- Reporter: VincentBerthoux2 | Owner: Type: bug | Status: new Priority: highest | Milestone: 7.10.2 Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: x86_64 Type of failure: Incorrect result | (amd64) at runtime | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by simonpj): Reid you are a marvel, thank you. My instinct is to "account for registers" overlapping. After all, if Cmm optimisations don't know that two registers are the same, all manner of bad things can happen, perhaps not limited to `CmmSink`. Is this just the Eq instance for `CmmReg`? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10521#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
