* [mips] Add support for the new mips-mti-linux toolchain.Vasileios Kalintiris2015-10-291-0/+2
| | | | | | | | | | The original commit in r249137 added the mips-mti-linux toolchain. However, the newly added tests of that commit failed in few buildbots. This commit re-applies the original changes but XFAILs the test file which caused the buildbot failures. This will allow us to examine what's going wrong without having to commit/revert large changes. llvm-svn: 251633

* Stop messing with the 'g' group of options in CompilerInvocation.Douglas Katzman2015-10-081-1/+4
| | | | | | | | | | | | | | | | With this change, most 'g' options are rejected by CompilerInvocation. They remain only as Driver options. The new way to request debug info from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}" and "-dwarf-version={2|3|4}". In the absence of a command-line option to specify Dwarf version, the Toolchain decides it, rather than placing Toolchain-specific logic in CompilerInvocation. Also fix a bug in the Windows compatibility argument parsing in which the "rightmost argument wins" principle failed. Differential Revision: http://reviews.llvm.org/D13221 llvm-svn: 249655

| | | | | | | | | | | r249137 added support for the new mips-mti-linux toolchain. However, the new tests of that commit, broke some buildbots because they didn't use the correct regular expressions to capture the filename of Clang & LLD.

* Add support for the new mips-mti-linux toolchain.Vasileios Kalintiris2015-10-021-0/+2
| | | | | | | | | | | | | | | | | | | | Summary: This new toolchain uses primarily LLVM-based tools, eg. compiler-rt, lld, libcxx, etc. Because of this, it doesn't require neither an existing GCC installation nor a GNU environment. Ideally, in a follow-up patch we would like to add a new --{llvm|clang}-toolchain option (similar to --gcc-toolchain) in order to allow the use of this toolchain with independent Clang builds. For the time being, we use the --sysroot option just to test the correctness of the paths generated by the driver.

* Driver: support ARM/HF on a single toolchainSaleem Abdulrasool2015-09-261-2/+3
| | | | | | | | | | | | | | | | | ARM EABI adds target attributes to the object file. Amongst the attributes that are emitted is the VFP argument passing (Hard vs Soft). The linker is responsible for checking these attributes and erroring on mismatches. This causes problems for the compiler-rt builtins when targeting both hard and soft. Because both of these options name the builtins compiler-rt component the same (libclang_rt.builtins-arm.a or libclang_rt.builtins-arm-android). GCC is able to get away with this as it does one target per toolchain. This changes the naming convention for the ARM compiler-rt builtins to differentiate between HF and Soft. Although this means that compiler-rt may be duplicated, it enables supporting both variants from a single toolchain. A similar approach is taken by the Darwin toolchain, naming the library to differentiate between the calling conventions. llvm-svn: 248649

* Driver: alter the getARMFloatABI signatureSaleem Abdulrasool2015-09-191-2/+1
| | | | | | | | | | This changes getARMFloatABI to use the ToolChain and Args instead of Driver, Args, Triple. Although this pushes the Triple calculation/parsing into the function itself, it enables the use of the function for a future change. The reason to sink the triple calculation here is to avoid threading the Triple through multiple layers in a future change. llvm-svn: 248095
* Driver: tweak ARM target feature calculationSaleem Abdulrasool2015-09-191-1/+2
| | | | | | | | | Rather than using re-calculating the effective triple, thread the already calculated value down into AddARMTargetArgs. This avoids both recreating the triple, as well as re-parsing the triple as it was already done in the previous frame. llvm-svn: 248094

| | | | | | | | | | | | To be able to handle -Wa, options in the assembler (ClangAs), we need to make the handling of options based on the value of the options, not direct Arguments from the list, since the list is immutable. No functional change in this patch, but this allows validating of -Wa,-mfpu and friends in the same way we validate -mfpu and friends, *just* for the assembler. llvm-svn: 243352

* Driver: add support for linking the UBSan runtime library on Windows.Peter Collingbourne2015-07-021-0/+3
| | | | | | | | | | | | | | On Windows the user may invoke the linker directly, so we might not have an opportunity to add runtime library flags to the linker command line. Instead, instruct the code generator to embed linker directive in the object file that cause the required runtime libraries to be linked. We might also want to do something similar for ASan, but it seems to have its own special complexities which may make this infeasible.

* Pedantically rename all Tool subclasses to be nouns, not verbs. NFCDouglas Katzman2015-06-231-231/+231
| | | | | | | | | | | | | | | | | | Classes in Tools.h inherit ultimately from Tool, which is a noun, but subclasses of Tool were named for their operation, such as "Compile", wherein the constructor call "Compile(args...)" could be misconstrued as actually causing a compile to happen. Likewise various other methods were not harmonious with their effect, in that "BuildLinker()" returned a "new namespace::Link(...)" instead of a "new namespace::Linker(...)" which it now does. Exceptions: Clang and ClangAs are un-renamed. Those are their rightful names. And there is no particulary great way to name the "Lipo-er" and a few others.

* Add nominal support for 'shave' target.Douglas Katzman2015-06-191-0/+27
| | | | | | | | | | | | | | This change passes through C and assembler jobs to Movidius tools by constructing commands which are the same as ones produces by the examples in the SDK. But rather than reference MV_TOOLS_DIR to find tools, we will assume that binaries are installed wherever the Driver would find its native tools. Similarly, this change assumes that -I options will "just work" based on where SDK headers get installed, rather than baking into the Driver some magic paths.

* Let Clang invoke CloudABI's linker.Ed Schouten2015-03-261-0/+16
| | | | | | | | | | | | | | | | | | | | | | Now that CloudABI's target information and header search logic for Clang has been submitted, the only thing that remains to be done is adding support for CloudABI's linker. CloudABI uses Binutils ld, although there is some work to use lld instead. This means that this code is largely based on what we use on FreeBSD. There are some exceptions, however: - Only static linking is performed. CloudABI does not support any dynamically linked executables. - CloudABI uses compiler-rt, libc++ and libc++abi unconditionally. Link in these libraries instead of using libgcc_s, libstdc++, etc. - We must ensure that the .eh_frame_hdr is present to make C++ exceptions work properly.

* Reapply "Change -save-temps to emit unoptimized bitcode files."Bob Wilson2014-12-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | This reapplies r224503 along with a fix for compiling Fortran by having the clang driver invoke gcc (see r224546, where it was reverted). I have added a testcase for that as well. Original commit message: It is often convenient to use -save-temps to collect the intermediate results of a compilation, e.g., when triaging a bug report. Besides the temporary files for preprocessed source and assembly code, this adds the unoptimized bitcode files as well. This adds a new BackendJobAction, which is mostly mechanical, to run after the CompileJobAction. When not using -save-temps, the BackendJobAction is combined into one job with the CompileJobAction, similar to the way the integrated assembler is handled. I've implemented this entirely as a driver change, so under the hood, it is just using -disable-llvm-optzns to get the unoptimized bitcode.

* Driver: add CrossWindowsToolChainSaleem Abdulrasool2014-10-241-0/+26
| | | | | | | | | | | | | | | | | | | | This is a very basic toolchain. It supports cross-compiling Windows (primarily inspired by the WoA target). It is meant to use clang with the LLVM IAS and a binutils ld-compatible interface for the linker (eventually to be lld). It does not perform any "standard" GCC lookup, nor does it perform any special adjustments given that it is expected to be used in an environment where the user is using MSVCRT (and as such Visual Studio headers) and the Windows SDK. The primary runtime library is expected to be compiler-rt and the C++ implementation to be libc++. It also expects that a sysroot has been setup given the usual Unix semantics (standard C headers in /usr/include, all the import libraries available in /usr/lib). It also expects that an entry point stub is present in /usr/lib (crtbegin.obj for executables, crtbeginS.obj for shared libraries). The entry point stub is responsible for running any GNU constructors. llvm-svn: 220546
