#15980: unpin a mutable byte array -------------------------------------+------------------------------------- Reporter: andrewthad | Owner: (none) Type: task | Status: new Priority: normal | Milestone: 8.6.3 Component: Compiler | Version: 8.6.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by carter): Hrrrmm. Do you have any examples where you can create excessive fragmentation? That’d be worth a ticket. One issue I see with adding such a primop is that it won’t be possible to respect alignment constraints that may have been expressed at bytearray allocation time. For unaligned bytearrays, you could just copy the buffer over to an unpinned array then copy it into the compact region -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15980#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
