#10283: Make it possible to suppress warnings produced by -fdefer-type-errors -------------------------------------+------------------------------------- Reporter: adamgundry | Owner: kanetw Type: feature request | Status: patch Priority: normal | Milestone: 7.12.1 Component: Compiler (Type | Version: 7.10.1 checker) | Keywords: newcomer Resolution: | Architecture: Operating System: Unknown/Multiple | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: Phab:D864 -------------------------------------+------------------------------------- Comment (by Ben Gamari ): In [changeset:"f753cf11eb9e310b54b08d9a1ea1d11540d8eb69/ghc"]: {{{ #!CommitTicketReference repository="ghc" revision="f753cf11eb9e310b54b08d9a1ea1d11540d8eb69" Allow deferred type error warnings to be suppressed Adds a flag -fwarn-deferred-type-errors similar to -fwarn-typed-holes. Changes the boolean flag of -fdefer-type-errors to a 3-state flag similar to the one used by -fdefer-typed-holes/-fwarn-typed-holes. Test Plan: Since only the absence of deferred type error warnings when -fno-warn-deferred-type-errors is passed has to be tested, I duplicated a test case checking -fdefer-type-errors and adjusted it accordingly.
