#14882: memchr# -------------------------------------+------------------------------------- Reporter: andrewthad | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D4472 Wiki Page: | -------------------------------------+------------------------------------- Comment (by dfeuer): Is there a benefit to baking it in as a primop rather than making it an FFI function in `base` or even `ghc-prim`? If not, I don't see the point. Personally, I suspect that there is not ''yet'' a benefit, but that there might be one in the future. In particular, if we ever have sufficient support for vector registers, we might get a small speed boost by implementing `memchr#` ourselves and inlining it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14882#comment:17 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
