#14982: LLVM default -mcpu setting inhibits customization -------------------------------------+------------------------------------- Reporter: tommd | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.4.2 Component: Compiler (LLVM) | Version: 8.4.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by angerman): The code in question pulls the `mcpu` (and `mattr`) from the new `llvm- targets` file. As such a hack around it right now would be to just modify the `llvm-targets` file. This however is a rather ugly hack as it would apply the logic globally. I guess we could just, as suggested, trop the `mcpu` from `llc` if a custom one is given. I'm not sure how to handle `mattr` though. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14982#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
