#11219: Implement fine-grained `-Werror=...` facility -------------------------------------+------------------------------------- Reporter: hvr | Owner: quchen Type: feature | Status: new request | Priority: normal | Milestone: 8.2.1 Component: Compiler | Version: Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: Design/Warnings -------------------------------------+------------------------------------- ...copied from Design/Warnings: Introduce variant of `-Werror` (c.f. GCC's `-Werror=*`) which allows to specify the individual warnings to be promoted to errors, e.g. - `-Wall -Werror=orphans` would only promote `-Worphans` warnings into errors - `-Wall -Werror -Wno-error=missing-methods` would promote all warnings //except// `-Wmissing-methods` into errors TODO: specify semantics a bit more exactly (the basic idea is to follow gcc/clang as much as sensible, and only deviate where it's necessary) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11219 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
