#8256: adding locality levels to prefetch# and friends -------------------------------------+------------------------------------ Reporter: carter | Owner: carter Type: task | Status: patch Priority: normal | Milestone: 7.8.1 Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: #8252 ,#8107 -------------------------------------+------------------------------------ Comment (by carter): well, there wasn't much discussion on the mailing list about whether can_fail is correct nor not! but to recap the mailing list reasons I laid out: 1. I think we're ok with inlining duplicating a prefetch operation 2. I'm not sure if we want to be ok with floating out prefetches (doing a prefetch earlier than planned). This is the reason for doing the can_fail = True annotation. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8256#comment:29 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
