#13633: testwsdeque failure on POWER8 -----------------------------------+--------------------------------------- Reporter: trommler | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Runtime System | Version: 8.1 Resolution: | Keywords: SMP Operating System: Linux | Architecture: powerpc64 Type of failure: Runtime crash | Test Case: rts/testwsdeque Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -----------------------------------+--------------------------------------- Comment (by trommler): Replying to [comment:1 simonmar]: the implementation, or the implementation of the barriers is wrong for POWER8. I looked at the implementation of the barriers and `cas()` in `SMP.h`again and they are correct for POWER and PowerPC. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13633#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
