#14838: missing "incomplete-patterns" warning for TH-generated functions -------------------------------------+------------------------------------- Reporter: gelisam | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.10.1 Component: Template Haskell | Version: 8.2.2 Resolution: | Keywords: | PatternMatchWarnings Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect | Unknown/Multiple error/warning at compile-time | Test Case: T14838 Blocked By: | Blocking: Related Tickets: #16169 | Differential Rev(s): Phab:D4440 Wiki Page: | -------------------------------------+------------------------------------- Comment (by RyanGlScott): For the sake of historical context, the original patch was in reverted in light of #14899, where it was discovered that the only reason that `singletons` compiles in a reasonable amount of time is because pattern- match coverage checking is disabled for generated code. Technically, the problem still exists if you were to write this code by hand, but we deemed `singletons` to be an important-enough reason not to keep the patch :) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14838#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
