#12070: SMP primitives broken on power(pc) -------------------------------------+------------------------------------- Reporter: hvr | Owner: trommler Type: bug | Status: patch Priority: highest | Milestone: 8.0.1 Component: Runtime System | Version: 8.0.1-rc4 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: powerpc Type of failure: None/Unknown | Test Case: | concurrent/prog001/concprog001 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D2225 Wiki Page: | -------------------------------------+------------------------------------- Changes (by trommler): * status: new => patch * differential: => Phab:D2225 Comment: Validated on powerpc64 and AMD64. Please, someone check that it does not break on ARM. The description for the built_in used in `xchg` suggests that the value stored in memory is implementation dependent. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12070#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
