supplied, use something derived from the system's temporary directory. Depends on LLVM r139725. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139726 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-17[driver] Clang doesn't support -mkernel/-fapple-kext for i386, so it's Chad Rosier

2011-07-09[arcmt] Introduce new '-ccc-arcmt-migrate <path>' ARC migration driver option.Argyrios Kyrtzidis
This is a new mode of migration, where we avoid modifying the original files but we emit temporary files instead. <path> will be used to keep migration process metadata. Currently the temporary files that are produced are put in the system's temp directory but we can put them in the <path> if is necessary. Also introduce new ARC migration functions in libclang whose only purpose, currently, is to accept <path> and provide pairs of original file/transformed file to map from the originals to the files after transformations are applied. Finally introduce the c-arcmt-test utility that exercises the new libclang functions, update arcmt-test, and add tests for the whole process. rdar://9735086. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134844 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-06Change the driver's logic about Objective-C runtimes: abstract out aJohn McCall
structure to hold inferred information, then propagate each invididual bit down to -cc1. Separate the bits of "supports weak" and "has a native ARC runtime"; make the latter a CodeGenOption. The tool chain is still driving this decision, because it's the place that has the required deployment target information on Darwin, but at least it's better-factored now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134453 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-02Make clang behave in a gcc-compatible way in the presence of multiple flags ↵Eli Friedman
for the same x86 target feature (e.g. -mno-sse -msse). gcc uses a somewhat unintuitive algorithm here in that the enabled SSE instructions is based on the order of the *last* flag for *each* feature-level, so that "-mno-sse -msse2" only enables SSE2, but "-mno-sse -msse2 -msse" enables all SSE levels.

2011-06-21Fix the default libc++ header search path to be sysrooted. Radar 9639692.Bob Wilson
The -cxx-isystem path is not prefixed with the sysroot directory, so it's not a good way for the driver to set the system default C++ search path. Instead, add -stdlib as a cc1 option and teach the frontend how to find the headers. The driver can then just pass -stdlib through to "cc1". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133547 91177308-0d34-0410-b5e6-96231b3b80d8
