#14731: Document alignment & underlying size invariants for array types in GHC.Prim -------------------------------------+------------------------------------- Reporter: jberryman | Owner: (none) Type: task | Status: new Priority: normal | Milestone: Component: Documentation | 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: #2917 #9806 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by jberryman): Documenting `newAlignedPinnedByteArray#` is also relevant. It seems that the alignment argument is only important for data that needs to be aligned to greater than word size (i.e. all byte arrays, pinned or not are word aligned). It's awkward to future-proof code for the case where GHC starts storing pinned arrays more tightly aligned. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14731#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
