* Remove the last remaining llvm/Config/config.h includesAlp Toker2014-06-04
| | | | | | | | | | | | This corrects long-standing misuses of LLVM's internal config.h. In most cases the public llvm-config.h header was intended and we can now remove the old hacks thanks to LLVM r210144. The config.h header is private, won't be installed and should no longer be included by clang or other modules. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@210145 91177308-0d34-0410-b5e6-96231b3b80d8
* Eliminate DefaultImageName from the Driver constructorAlp Toker2014-05-15
| | | | | | | | | | | | All callers were passing in "a.out" or garbage so a sensible default works fine here as a cleanup. This also brings about the possibility of adapting the value based on the driver's compatibility mode in future. The setting can still be changed via Driver::DefaultImageName as needed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@208926 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove support for the QA_OVERRIDE_GCC3_OPTIONS environment variable.Bob Wilson2014-02-23
| | | | | | | | | | In r199283 I switched the name of this variable to CCC_OVERRIDE_OPTIONS, but I kept some code to continue recognizing the old name temporarily. As far as I know, the only use of this was for some internal testing at Apple, and we've now switched to use the new name. If anyone else is still using this and needs more time to switch names, I guess we'll find out! <rdar://problem/15821425> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@201962 91177308-0d34-0410-b5e6-96231b3b80d8

* Turn Driver::CCCIsCXX and CCCIsCPP into a single Mode enum,Hans Wennborg2013-07-18
| | | | | | | | | | | | and add a new option --driver-mode= to control it explicitly. The CCCIsCXX and CCCIsCPP flags were non-overlapping, i.e. there are currently really three modes that Clang can run in: gcc, g++ or cpp, so it makes sense to represent them as an enum. Having a command line flag to control it helps testing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@186605 91177308-0d34-0410-b5e6-96231b3b80d8
* [Driver] Use LLVM's response file parser because it can read UTF-16Reid Kleckner2013-07-18
| | | | | | | | | | | | MSBuild writes response files as UTF-16 little endian with a byte order mark. With this change, clang will be able to read them, although we still can't parse any of their flags. Adds a UTF-16-LE response file with a BOM for testing.

* [Driver] Refactor clang driver to use LLVM's Option libraryReid Kleckner2013-06-14

* [driver] Parse diagnostic args in the driver.Chad Rosier2012-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously, only diagnostics thrown by the cc1 process were actually honoring the diagnostic options given on the command line, like -Werror. Reuse the existing code in Frontend currently used for cc1, adjusting it to not interpret -Wl, linker flags as warnings. Also fix a faulty test exposed by this change. It wasn't actually testing anything, and was giving this warning: clang-3: warning: argument unused during compilation: '-verify' Which -Werror didn't turn into an error because it was output by the driver, not the cc1 process, and diagnostic options weren't parsed by the driver. And you couldn't see the warning when running the test suite. Fixes PR12181.
