#8272: testing if SpLim=$rbp and Sp=$rsp changed performance at all -------------------------------------+------------------------------------- Reporter: carter | Owner: carter Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.7 Resolution: | Keywords: | callingConvention Operating System: Unknown/Multiple | Architecture: x86_64 Type of failure: Runtime | (amd64) performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): In my view (1) is really the more interesting change as it enables use of native profiling tools. Currently we are essentially unable to use systems' native profiling tools to collect callstacks (e.g. `perf record --callgraph`) since they generally assume that the callstack is tracked by `%rsp`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8272#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
