* Remove the Darwin_Generic_GCC toolchain.Rafael Espindola2013-11-241-7/+1
| | | | | | | | | | | This is currently unused by any test. The code path would still be hit by clang on ppc, but * PPC has not been supported on current versions of OS X * A port of current clang to older OS X on ppc should be using toolchains::DarwinClang. llvm-svn: 195585
* SanitizerArgs: add ability to filter/diagnose unsupported sanitizers.Peter Collingbourne2013-11-011-8/+0
| | | | | | | | | | | | The thread, memory, dataflow and function sanitizers are now diagnosed if enabled explicitly on an unsupported platform. Unsupported sanitizers which are enabled implicitly (as part of a larger group) are silently disabled. As a side effect, this makes SanitizerArgs parsing toolchain-dependent (and thus essentially reverts r188058), and moves SanitizerArgs ownership to ToolChain.

* clang-cl: diagnose setting asm listing filename with multiple inputsHans Wennborg2013-10-181-1/+12

* clang-cl: Add support for asm listings (/FA and /Fa)Hans Wennborg2013-10-171-2/+17
| | | | | | | | | | This adds support for outputing the assembly to a file during compilation. It does this by changing the compilation pipeling to not use the integrated assembler, and keep the intermediate assembler file.

* Produce an error if a -cc1 only option is passed to the driver.Rafael Espindola2013-09-251-1/+1
| | | | llvm-svn: 191380
* Produce errors for unknown options.Rafael Espindola2013-09-231-0/+5
| | | | | | | | | This doesn't change a lot since clang still thinks it knows all of the -f*, -m* and -W* options for example. Other than the options clang explicitly claims to know, this fixes pr9701. llvm-svn: 191249
* clang-cl: Don't warn about overriding /MD with /MT, /Fo with another /Fo, etc.Hans Wennborg2013-09-181-22/+0
| | | | | | | | | | | | | | | | I put in the warnings because MSVC has them, but I don't think they're very useful. Clang does not warn about overriding flags in general, e.g. it's perfectly fine to have -fomit-frame-pointer followed by -fno-omit-frame-pointer. We should focus on warning where things get confusing, such as with the /TP and /TC options. In "clang-cl /TC a.c /TP b.cc", the user might not realize that the /TP flag will apply to both files, and we warn about that.

* clang-cl: ignore compile-only options in link-only invocations.Hans Wennborg2013-09-171-1/+6
| | | | | | | | | | | Previously we would warn about unused arguments such as /MD when linking. Clang already has logic to ignore compile-only options, e.g. for -D and -U. This patch extends that to include clang-cl's compile-only options too. Also, some clang-cl options should always be ignored. Doing this earlier means they get ignored both for compilation and link-only invocations. llvm-svn: 190825
* Move Compilation::PrintJob and PrintDiagnosticJob into Job::Print.Hans Wennborg2013-09-121-3/+3
| | | | | | | | | | | | | | | | | This moves the code to Job.cpp, which seems like a more natural fit, and replaces the "is this a JobList? is this a Command?" logic with a virtual function call. It also removes the code duplication between PrintJob and PrintDiagnosticJob and simplifies the code a little. There's no functionality change here, except that the Executable is now always printed within quotes, whereas it would previously not be quoted in crash reports, which I think was a bug.

* clang-cl: Warn about overriding /MD with /MT etc.Hans Wennborg2013-09-111-2/+2
| | | | | | | This also bakes the /M options into a separate option group to make them easier to refer to from the code. llvm-svn: 190529
* clang-cl: Support building DLLs (PR17083)Hans Wennborg2013-09-101-6/+14
| | | | | | | | This adds driver support for building DLLs (the /LD and /LDd flags). It basically does two things: runtime selection and passing -dll and -implib to the linker. llvm-svn: 190428
* clang-cl: Use .obj as extension for unnamed object files (PR17095)Hans Wennborg2013-09-051-1/+1
| | | | | | | | We already use .obj as extension when the user provides a stem file name (via /Fo), but were failing in the most basic case when the file name is based on the input file. llvm-svn: 190071
* Use -### instead of -ccc-print-options.Rafael Espindola2013-09-031-26/+2
| | | | | | | Convert the last few tests using -ccc-print-options to -### and remove -ccc-print-options. llvm-svn: 189802
* Produce an error when trying to link with -emit-llvm.Rafael Espindola2013-08-251-0/+4

* Don't imply -flto with -O4.Rafael Espindola2013-08-231-4/+0
| | | | | | We now saturate at -O3. llvm-svn: 189149
* Driver::IsUsingLTO() no longer return true when seeing -emit-llvm.Shuxin Yang2013-08-231-3/+5
| | | | | | | | | | One step toward differentiating following two commands: clang -O3 -flto a.c -c, and clang -O3 -emit-llvm a.c Thanks many awesome folks for clarifying things. llvm-svn: 189148
* Move SanitizerArgs to the clang DriverAlexey Samsonov2013-08-191-0/+8
| | | | | | | | | | | | | | | | Summary: This change turns SanitizerArgs into high-level options stored in the Driver, which are parsed lazily. This fixes an issue of multiple copies of the same diagnostic message produced by sanitizer arguments parser.

* Driver::IsUsingLTO() no longer return true when seeing -emit-llvm.Shuxin Yang2013-08-141-3/+5
| | | | | | | | | | The rationale for this change is to differentiate following two situations: 1) clang -c -emit-llvm a.c 2) clang -c -flto a.c Reviewed by Eric Christopher. Thanks a lot! llvm-svn: 188352
* clang-cl: Support /link option and set target to win32Hans Wennborg2013-08-131-0/+6
| | | | | | | | | | | | | This adds support for the /link option, which forwards subsequent arguments to the linker. The test for this will only work when targetting win32. Since that's the only target where clang-cl makes sense, use that target by default. Differential Revision: http://llvm-reviews.chandlerc.com/D1388 llvm-svn: 188331
* Handle "--" explicitly in the driverHans Wennborg2013-08-131-9/+17
| | | | | | | | | | Anything that comes after -- is treated as an input file. This used to be handled automagically by the option parsing library, but after LLVM r188314, we should handle it ourselves. No functionality change. llvm-svn: 188316

* clang-cl: add the /c, /W0 and /W1 optionsHans Wennborg2013-07-311-3/+3
| | | | | | | | | | This adds a few more clang-cl options. It also exposes two core clang options to the clang-cl mode: we need to be able to claim --driver_mode so it doesn't show up as unused in cl mode, and we need -### for tests.

* Start keeping track of what work was done to detect a GCC installationChandler Carruth2013-07-301-0/+4
| | | | | | | | | | | | on the system, and report it when running the driver in verbose mode. Without this it is essentially impossible to understand why a particular GCC toolchain is used by Clang for libstdc++, libgcc, etc. This also required threading a hook through the toolchain layers for a specific toolchain implementation to print custom information under 'clang -v'. The naming here isn't spectacular. Suggestions welcome. llvm-svn: 187427
* clang-cl: add support for the /? and /help optionsHans Wennborg2013-07-271-4/+36
| | | | | | | | | | | | | | This establishes a new Flag in Options.td, which can be assigned to options that should be made available in clang's cl.exe compatible mode, and updates the Driver to make use of the flag. (The whitespace change to CMakeLists forces the build to re-run CMake and pick up the include dependency on the new .td file. This makes the build work if someone moves backwards in commit history after this change.) Differential Revision: http://llvm-reviews.chandlerc.com/D1215 llvm-svn: 187280
* [PowerPC] Support powerpc64le as a syntax-checking target.Bill Schmidt2013-07-261-0/+8
| | | | | | | | | | | | | | | | | | | This patch provides basic support for powerpc64le as an LLVM target. However, use of this target will not actually generate little-endian code. Instead, use of the target will cause the correct little-endian built-in defines to be generated, so that code that tests for __LITTLE_ENDIAN__, for example, will be correctly parsed for syntax-only testing. Code generation will otherwise be the same as powerpc64 (big-endian), for now. The patch leaves open the possibility of creating a little-endian PowerPC64 back end, but there is no immediate intent to create such a thing. The new test case variant ensures that correct built-in defines for little-endian code are generated. llvm-svn: 187180

* Turn Driver::CCCIsCXX and CCCIsCPP into a single Mode enum,Hans Wennborg2013-07-181-10/+40
| | | | | | | | | | | | 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. llvm-svn: 186605
