#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 rwbarton): Confusingly, GCC's locality levels 0, 1, 2, 3 correspond to Intel instructions `prefetchnta`, `prefetcht2`, `prefetcht1`, `prefetcht0` respectively, but there's not much we can do about that (except document it clearly, I guess). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8256#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
