#14977: Clang doesn't support -Wsync-nand -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.4.1 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: -------------------------------------+------------------------------------- 94f02547083cf6df686ea0b95fed050184c533de added a `#pragma GCC diagnostic ignored "-Wsync-nand"` pragma to `libraries/ghc-prim/cbits/atomic.c` to silence `-Werror` failures due to GCC's non-actionable `-Wsync-nand` warning. Unfortunately goldfire reports that Apple's Clang chokes on this with, {{{ libraries/ghc-prim/cbits/atomic.c:127:32: error: unknown warning group '-Wsync-nand', ignored [-Werror,-Wunknown-warning-option] }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14977 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
