#16305: When should -Wmissed-specializations fire? -------------------------------------+------------------------------------- Reporter: crockeea | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Poor/confusing | Unknown/Multiple error message | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by crockeea): I should point out that the fact that `-Wmissed-specs` doesn't create a warning in the example above seems to (according to the code) be due to `showsPrec` not having any type of inline pragma. The following evaluates to `False` on `f=showsPrec`: `has_inline_prag f = isAnyInlinePragma (idInlinePragma f)` -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16305#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
