#13257: out-of-range warnings for negative literals, without -XNegativeLiterals -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: ruperthorlick Type: feature request | Status: patch Priority: normal | Milestone: Component: Compiler | Version: 8.1 Resolution: | Keywords: newcomer Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: | deSugar/should_compile/T13257 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D3281 Wiki Page: | -------------------------------------+------------------------------------- Comment (by monoidal): Is it correct not to warn about `-128 :: Int8` when `-XNegativeLiterals` is off? After all, without -XNegativeLiterals this means creating the overflowed integer `128 :: Int8` and only then negating it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13257#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
