2012-01-25Remove the 'ToolTriple' concept from the NetBSD toolchain along with myChandler Carruth
gross hack to provide it from my previous patch removing HostInfo. This was enshrining (and hiding from my searches) the concept of storing and diff-ing the host and target triples. We don't have the host triple reliably available, so we need to merely inspect the target system. I've changed the logic in selecting library search paths for NetBSD to match what I provided for FreeBSD -- we include both search paths, but put the 32-bit-on-64-bit-host path first so it trumps. NetBSD maintainers, you may want to tweak this, or feel free to ask me to tweak it. I've left a FIXME here about the challeng I see in fixing this properly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148952 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-25Switch the ToolChain types to all store a Driver reference rather thanChandler Carruth
a HostInfo reference. Nothing about the HostInfo was used by any toolchain except digging out the driver from it. This just makes that a lot more direct. The change was accomplished entirely mechanically. It's one step closer to removing the shim full of buggy copy/paste code that is HostInfo. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148945 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-25Make a major refactoring to how the GCC installation detection works.Chandler Carruth
The fundamental shift here is to stop making *any* assumptions about the *host* triple. Where these assumptions you ask? Why, they were in one of the two target triples referenced of course. This was the single biggest place where the previously named "host triple" was actually used as such. ;] The reason we were reasoning about the host is in order to detect the use of '-m32' or '-m64' flags to change the target. These flags shift the default target only slightly, which typically means a slight deviation from the host. When using these flags, the GCC installation is under a different triple from the one actually targeted in the compilation, and we used the host triple to find it. Too bad that wasn't even correct. Consider an x86 Linux host which has a PPC64 cross-compiling GCC toolchain installed. This toolchain is also configured for multiarch compiling and can target PPC32 with eth '-m32' flag. When targeting 'powerpc-linux-gnu' or some other PPC32 triple, we have to look for the PPC64 variant of the triple to find the GCC install, and that triple is neither the host nor target. The new logic computes the multiarch's alternate triple from the target triple, and looks under both sides. It also looks more aggressively for the correct subdirectory of the GCC installation, and exposes the subdirectory in a nice programmatic way. This '/32' or '/64' suffix is something we can reuse in many other parts of the toolchain. An important note -- while this likely fixes a large category of cross-compile use cases, that's not my primary goal, and I've not done testing (or added test cases) for scenarios that may now work. If someone else wants to try more interesting PPC cross compiles, I'd love to have reports. But my focus is on factoring away the references to the "host" triple. The refactoring is my goal, and so I'm mostly relying on the existing (pretty good) test coverage we have here. Future patches will leverage this new functionality to factor out more and more of the toolchain's triple manipulation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148935 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-24Address one part of the FIXME I introduced my switching the tripleChandler Carruth
inside of GCCInstallation to be a proper llvm::Triple. This is still a touch ugly because we have to use it as a string in so many places, but I think on the whole the more structured representation is better. Comments of course welcome if this tradeoff isn't working for folks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148843 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-17Split the Windows toolchain definition into its own file. This isChandler Carruth
especially nice as the Windows toolchain needs the windows header files, and has lots of platform specific hooks in it. To facilitate the split, hoist a bunch of file-level static helpers into class-level static helpers. Spiff up their doxygen comments while there as they're now more likely to be looked up via docs. Hopefully, this will be followed by further breaking apart of the toolchain definitions. Most of the large and complex ones should likely live on their own. I'm looking at you Darwin. ;] git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146840 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-09Fix an issue that Duncan discovered on a specific (no longer current)Chandler Carruth
version of Ubuntu. It has a very broken multiarch configuration, and so we need special logic to handle it correctly. Fixing and testing this uncovered a few other trivial issues with the logic that are fixed as well. I added tests to cover this as it is hard to notice if you install recent versions of the OS. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144165 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-06Move the GCC installation detection logic down into the Generic_GCCChandler Carruth
toolchain. The logic is mostly generic already, and where possible should be made more generic. Also, it has no impact other than to expose a set of methods which each toolchain can then query to setup their desired configuration. These should be available to toolchains beyond just Linux. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143899 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-05Remove a pointless member. I have no idea why I made this not a localChandler Carruth
variable to begin with... As I'm planning to add include root information to this object, this would have caused confusion. It didn't even *actually* hold the include root by the time we were done with it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143840 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-05Move the GCC installation detection helper a member of the LinuxChandler Carruth
toolchain instead of merely using it in the constructor. This will allow us to query it when building include paths as well as the file search paths built in the constructor. I've lifted as little of it as I could into the header file. Eventually this will likely sink down into some of the Generic toolchains and be used on more platforms, but I'm starting on Linux so I can work out all the APIs needed there, where it is easiest to test and we have the most pressing need. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143838 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-05Move the Linux header searching from the Frontend to the Driver. This isChandler Carruth
the first (and diff-noisiest) step to making Linux header searching tremendously more principled and less brittle. Note that this step should have essentially no functional impact. We still search the exact same set of paths in the exact same order. The only change here is where the code implementing such a search lives. This has one obvious negative impact -- we now pass a ludicrous number of flags to the CC1 layer. That should go away as I re-base this logic on the logic to detect a GCC installation. I want to do this in two phases so the bots can tell me if this step alone breaks something, and so that the diffs of the refactoring make more sense. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143822 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-20For i386 kext fallback to llvm-gcc, search paths for several Darwin versions.Bob Wilson
This replaces the hack to read UNAME_RELEASE from the environment when identifying the OS version on Darwin, and it's more flexible. It's also horribly ugly, but at least this consolidates the ugliness to touch less of the code so that it will be easier to rip out later. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140187 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-07Use ld directly on linux. Changes from the previous try:Rafael Espindola
*) Try to detect as much as possible from the system itself, not the distro. This should make it easier to port to a new distro and more likely to work on a unknown one. *) The distro enum now doesn't include the arch. Just use the existing host detection support in LLVM. *) Correctly handle --sysroot. A small regression is that now clang will pass bitcode file to the linker.
