#7902: Add support for byte endianness swapping exposed as a primops -----------------------------+---------------------------------------------- Reporter: tab | Owner: Type: feature request | Status: new Priority: normal | Component: Compiler Version: 7.7 | Keywords: bswap endianness Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: None/Unknown | Blockedby: Blocking: | Related: -----------------------------+---------------------------------------------- Add support for W32 and W64 endianness swapping as a new primops (bSwap32# and bSwap64#), supported by code generator change in llvm and ncg to generate efficient code (i.e. X86's bswap instruction support). For other NCG architectures (powerpc, sparc) provide support by 2 ghc-prim C functions. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7902 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
