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.

2011-11-14Don't track depfiles as result files which need to be cleaned up on failure.Matt Beaumont-Gay
This is a partial revert of r143846. While cleaning up after a crash is probably a good idea, we were also deleting .d files if the compilation failed due to invalid input, which is not the desired behavior. The test is XFAIL'd until the cleanup code can be reworked to do the right thing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144590 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2011-11-09Fix an issue that Duncan discovered on a specific (no longer current)Chandler Carruth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.

2011-11-08Add a default system include of '/include'. This isn't particularlyChandler Carruth
useful when using Clang as a system-compiler, but its harmless. When using Clang as a cross-compiler, this can be very handy as quite a few toolchains ship their libc headers here rather than under '/usr/include'. For reference, this is the beginning of my work to also make the Clang driver more suitable as a cross-compiler. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144089 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-07Rip out one of the features I added for the driver-include-management.Chandler Carruth
We don't actually need a separate flag for non-sysrooted paths as the driver has to manage the sysroot anyways. The driver is not infrequently adding paths to the header search based on their existence on the filesystem. For that, it has to add the sysroot anyways, we should pass it on down to CC1 already joined. More importantly, the driver cannot in all cases distinguish between sysrooted paths and paths that are relative to the Clang binary's installation directory. Essentially, we always need to ignore the system root for these internal header search options. It turns out in most of the places we were already providing the system root in the driver, and then another one in CC1 so this fixes several bugs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143917 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
