#7902: Add support for byte endianness swapping exposed as a primops -----------------------------+---------------------------------------------- Reporter: tab | Owner: Type: feature request | Status: patch Priority: normal | Component: Compiler Version: 7.7 | Keywords: bswap endianness Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: None/Unknown | Blockedby: Blocking: | Related: -----------------------------+---------------------------------------------- Comment(by tab): * I started originally with a bSwap16# too, but i removed it to focus on the 32 bits version and make sure i'ld plumb it in all the correct place. bSwap16# is not very hard indeed and i can re-add it properly quickly now i'm a bit more familiar with ghc's codegen. * I'm not sure how to expose it to the world, as Bits is quite big and not sure what byte endianess reversing mean for signed int and such. So i'll be happy to expose it somewhere following some discussion and direction on this. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7902#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
