#9706: New block-structured heap organization for 64-bit -------------------------------------+------------------------------------- Reporter: ezyang | Owner: simonmar Type: task | Status: new Priority: normal | Milestone: Component: Runtime | Version: 7.8.3 System | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: None/Unknown | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by simonpj): Sounds plausible to me, but what is the benefit? We seem to get * More complicated code (since we still need the megablocks for 32-bit) in exchange for... what? I'm sure there is something, but it would be worth making the cost/benefit tradeoff explicit. Also, as 32-bit architectures wane, would there be a simpler but perhaps- less-performant fallback that would allow the code to be simplified for all architectures? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9706#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
