#8578: Improvements to SpinLock implementation -------------------------------------+------------------------------------- Reporter: parcs | Owner: (none) Type: task | Status: new Priority: normal | Milestone: Component: Runtime System | Version: 7.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by dfeuer): Since thoughtpolice mentioned them, I'm wondering if there are specific places we should look at as HLE (or perhaps RTM) candidates. I don't ''think'' we can rely on the system glibc to use them to implement mutexes unless we ask for that specifically in some fashion. I'd expect very small and short transactions (most but not all of what we do) to benefit. Has anyone looked into that yet? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8578#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
