#8561: Clang/iOS: __builtin___clear_cache doesn't exist in clang, use __clear_cache instead -------------------------------------+------------------------------------- Reporter: lukexi | Owner: Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 7.6.3 Resolution: | Keywords: Operating System: Other | Architecture: Unknown/Multiple Type of failure: Building GHC | Difficulty: Easy (less than 1 failed | hour) Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------- Comment (by carter): heatsink is likely to follow up on this, but GCC 4.2 lacks the builtin clear cache primitive, and thus any OS X system with XCode < 5 has a GCC old enough that builtin___clear_cache shoudn't be used. (at least if we want to support working at all on older OS X systems, which i think is worth doing) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8561#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
