#7902: Add support for byte endianness swapping exposed as a primops ------------------------------------------+--------------------------------- Reporter: tab | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.7 Resolution: | Keywords: bswap endianness Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: None/Unknown | Difficulty: Unknown Testcase: codeGen/should_run/cgrun072 | Blockedby: Blocking: | Related: ------------------------------------------+--------------------------------- Comment(by tab): ah #7976 is already a bit further than my investigation. So far i came to the same conclusion of the problem being the 64 bits flavor of byteSwap. I think the patch make sense (without considering the overlapping), the 32 bit version for i386 definitely need a specific version for bswap64. I don't think it should be an issue with the 32 bits in general, as ppc and sparc (the other NCG platforms) will be handled with the C functions. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7902#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
