#14882: memchr# -------------------------------------+------------------------------------- Reporter: andrewthad | Owner: (none) Type: feature | Status: new request | Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 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: -------------------------------------+------------------------------------- It would be neat if we had a primitive for calling memchr on a ByteArray#. Something like this: {{{ memchr :: ByteArray# -> Word# -> Int# -> Int# -> Int# }}} The integer arguments are a starting index and length. I have a hunch that copyByteArray# and friends are just wrappers for memcpy that somehow prohibit the array from being moved by the GC while they are running. I would be happy to try to implement memchr# if it seems like an alright idea. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14882 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
