#10600: -fwarn-incomplete-patterns doesn't work with -fno-code -------------------------------------+------------------------------------- Reporter: akio | Owner: ezyang Type: bug | Status: new Priority: normal | Milestone: 8.4.1 Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect | Unknown/Multiple warning at compile-time | Test Case: driver/T8101b Blocked By: | Blocking: Related Tickets: #8101 | Differential Rev(s): Phab:D1278 Wiki Page: | -------------------------------------+------------------------------------- Comment (by mpickering): Thanks Doug, that's a useful summary. My main concern is a code hygiene. It is a fundamental design principle that we typecheck the code before desugaring so that error messages are better. By checking these things in the desugarer we might be trading good error messages for an easier implementation which I think is in general undesirable. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10600#comment:25 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
