[GHC] #8396: cleanup / refactor native code gens
#8396: cleanup / refactor native code gens ----------------------------------------+---------------------------------- Reporter: carter | Owner: Type: feature request | Status: new Priority: high | Milestone: 7.10.1 Component: Compiler | Version: Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Unknown | Type of failure: None/Unknown Blocked By: | Test Case: Related Tickets: #8299 , #8287 ,#8272 | Blocking: ----------------------------------------+---------------------------------- the native code gen could use some cleanup / love. 1. Catchup with feature parity of the llvm a. this includes adding SIMD support on applicable native code gen architectures, starting with x86_64 2. make it easier to extend / modify experiment with the native code gen 3. make it easier to add new primops (maybe even a magic inline asm primop?!) 4. other things i'm overlooking right now this also overlaps with a number of related tickets i've been adding to trac. a more ambitious strategic goal that won't be the initial goal, that simon marlow suggested when i chatted with him at ICFP, is to make the native code gen codebase a sort of "mini-llvm". I think thats a bit ambitious for the near term, but maybe thats the point on the horizon we may want to aim towards. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8396 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Currently HOOPL isn't used at all! This is because a *single* hoopl pass will apparently increase the compilation time of programs by 5%, so adding a number of hoopl passes would seriously blow up the compilation time. i'm not really touching on improving the optimization story, that'd be a subsequent effort and much more work. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8396#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
