#5556: Support pin-changing on ByteArray#s -------------------------------------+------------------------------------- Reporter: pumpkin | Owner: Type: feature | Status: new request | Milestone: 7.10.1 Priority: normal | Version: 7.2.1 Component: Compiler | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: None/Unknown | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by rwbarton): Let me make sure I've got this right: pinned ByteArrays currently live on a totally different heap than unpinned ones, right? If you pin an unpinned ByteArray without copying it, now you have a hole in the middle of your GC area to allocate around. I suppose you could split the containing GC block into two? a reasonable thing to do if you don't expect many temporarily- pinned ByteArrays to exist at any given time. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5556#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
