#11549: Add -fshow-runtime-rep -------------------------------------+------------------------------------- Reporter: goldfire | Owner: goldfire Type: bug | Status: new Priority: highest | Milestone: 8.0.1 Component: Compiler | Version: 8.1 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 RyanGlScott): One thing isn't clear to me about how `-fshow-runtime-rep` works. I'm assuming that without `-fshow-runtime-rep` on, you won't see any mention of `RuntimeRep` in error messages. If so, what kind of error would this produce? {{{#!hs import GHC.Exts bad :: forall (w :: RuntimeRep) (a :: TYPE w). a -> Int bad _ = 42 }}} The error would probably mention the type signature of `bad`, but would it be truncated to `a -> Int` instead of the full shebang? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11549#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
