#13107: Negative literal equal to minBound gives a spurious warning -------------------------------------+------------------------------------- Reporter: erikd | Owner: Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: invalid | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect | Unknown/Multiple error/warning at compile-time | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by rwbarton): * status: new => closed * resolution: => invalid Comment: I don't see the problem here, although the warning requires careful reading. `-128` is the application of unary minus to the literal `128`. The literal `128` that you wrote does indeed lie outside of the `Int8` range as the warning states. And the warning even suggested turning on `NegativeLiterals`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13107#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
