#9777: -msse flag could be handled better by the driver -------------------------------------+------------------------------------- Reporter: jstolarek | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Driver | Version: 7.9 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Moderate (less | Type of failure: Other than a day) | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- I bumped into two small issues with `-msse` and `-msse4.2` flags: 1. GHC accepts any flag of the form `-msseX.Y`, eg. `-msse3.14`. I think we should validate numbers passed by the user or - even better - pre- define a set of allowed `-msse` flags. Currently we have this definition: {{{ Flag "msse" (versionSuffix (\maj min d -> d{ sseVersion = Just (maj, min) })) }}} 2. A direct consequence of above definition is that bash command-line auto-completion does not suggest `-msse4.2` flag. This is somewhat related to Austin's Phab:D165 -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9777 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
