[GHC] #11037: Expose pop count primitives to cmm
#11037: Expose pop count primitives to cmm -------------------------------------+------------------------------------- Reporter: ekmett | Owner: Type: feature | Status: new request | Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- I can't actually invoke the various `MO_PopCnt width` prim ops from the literal Cmm syntax. Would it be possible to expose them via `machOps` in `CmmParse.y` as `popcnt8`, `popcnt16`, etc.? This would enable me to generate much more efficient code. I started hacking up a mostly Cmm-side implementation of a HashMap. This lets me directly index into fields in data constructors and the like, eliding the indirection of the array machinery and allowing a much more direct implementation. Other than this, until this point it has been going remarkably smoothly. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11037 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
