#10137: Rewrite switch code generation -------------------------------------+------------------------------------- Reporter: nomeata | Owner: Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.9 (CodeGen) | Keywords: Resolution: | Architecture: Operating System: Unknown/Multiple | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #9157, #8326, | Differential Revisions: #8317 | -------------------------------------+------------------------------------- Comment (by nomeata): All very well, but can we please keep this particular ticket for the discussion of better code generation from STG onwards :-) #10124 is more suitable for what we can do in Core, I think. My rewrite will not only fix the issue of branchless cases, but also other (small) deficiencies in the current code (jump tables also for integer types; a better choice for if-then-else branching that leads to larger jump tables). Anyway, I started on wip/T10137, but already my refactoring broke something and I get segfaults :-) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10137#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
