#14372: CMM contains a bunch of tail-merging opportunities -------------------------------------+------------------------------------- Reporter: heisenbug | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): Poorly predicted branches can indeed be expensive. However, I think here we are just taking about jumps which, as far as I know, are quite cheap assuming they don't boot you out of $I since they can be predicted perfectly. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14372#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
