[GHC] #7690: iOS patch no 1: Select operating system

#7690: iOS patch no 1: Select operating system ------------------------------+--------------------------------------------- Reporter: StephenBlackheath | Owner: Type: bug | Status: new Priority: normal | Component: Compiler Version: 7.7 | Keywords: Os: Other | Architecture: arm Failure: None/Unknown | Blockedby: Blocking: | Related: ------------------------------+--------------------------------------------- This is the first in a series of patches for adding cross-compile ability for iOS. For now, 'arm-apple-darwin10' will be interpreted as iOS. Later we will need to tweak this to detect the difference between the iOS simulator (with an i386 cpu) and the native Mac. I am creating a new logical OS name 'ios' because the differences between iOS and Mac can be quite significant. I thought it would we best not to introduce the idea of an OS variant (as we did with ARM cpus) for two reasons: 1. it's over-complicating the issue and 2. it would require some modification of cabal. Versioning: I'm submitting patch version 1a here. If I have to revise a patch, I'll bump the letter. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7690> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

The CROSS_COMPILE variable was used to turn on behaviour in certain modules, but is now obsolete. So let's remove it. With this patch applied, CROSS_COMPILE appears nowhere in the build tree. I also tested it by building an ARM-linux cross compiler. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7699> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#5987: Too many symbols in ghc package DLL ---------------------------------+------------------------------------------ Reporter: igloo | Owner: Type: bug | Status: new Priority: highest | Milestone: 7.8.1 Component: Compiler | Version: 7.5 Keywords: | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: None/Unknown Difficulty: Unknown | Testcase: Blockedby: | Blocking: 3658 Related: | ---------------------------------+------------------------------------------ Changes (by rassilon): * cc: bill@… (added) Comment: Here's a pretty nutty idea: What if we split the DLL in parts by automatically forcing the .o files into partitions and create a .def file for each partition thus breaking the import library cycle. GHC already uses .def files to break the cycle between the RTS and the base DLLs. Then you would "just" modify Cabal to understand partitioned DLLs. Unfortunately, this might end up increasing the total number of partitions if you're not careful because internal symbols would now need to be exported from the partitions. :( -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/5987#comment:15> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
