2016-10-27[Driver][OpenMP] Add support to create jobs for unbundling actions.Samuel Antao1-5/+8
Summary: This patch adds the support to create jobs for the `OffloadBundlingAction` which will invoke the `clang-offload-bundler` tool to unbundle input files. Unlike other actions, unbundling actions have multiple outputs. Therefore, this patch adds the required changes to have a variant of `Tool::ConstructJob` with multiple outputs. The way the naming of the results is implemented is also slightly modified so that the same action can use a different offloading prefix for each use by the different offloading actions. With this patch, it is possible to compile a functional OpenMP binary with offloading support, even with separate compilation.

2016-10-27[Driver][OpenMP] Update actions builder to create unbundling action when ↵Samuel Antao1-0/+10
necessary. Summary: Each time that offloading support is requested by the user and the input file is not a source file, an action `OffloadUnbundlingAction` is created to signal that the input file may contain bundles, so that the proper tool is then invoked to attempt to extract the components of the bundle. This patch adds the logic to create that action in offload action builder. The job creation for the new action will be proposed in a separate patch.

2016-10-27[Driver][OpenMP] Update actions builder to create bundling action when ↵Samuel Antao1-0/+7
necessary. Summary: In order to save the user from dealing with multiple output files (for host and device) while using separate compilation, a new action `OffloadBundlingAction` is used when the last phase is not linking. This action will then result in a job that uses the proposed bundling tool to create a single preprocessed/IR/ASM/Object file from multiple ones. The job creation for the new action will be proposed in a separate patch.

2016-07-15[CUDA][OpenMP] Create generic offload actionSamuel Antao1-9/+208
Summary: This patch replaces the CUDA specific action by a generic offload action. The offload action may have multiple dependences classier in “host” and “device”. The way this generic offloading action is used is very similar to what is done today by the CUDA implementation: it is used to set a specific toolchain and architecture to its dependences during the generation of jobs. This patch also proposes propagating the offloading information through the action graph so that that information can be easily retrieved at any time during the generation of commands. This allows e.g. the "clang tool” to evaluate whether CUDA should be supported for the device or host and ptas to easily retrieve the target architecture. This is an example of how the action graphs would look like (compilation of a single CUDA file with two GPU architectures) ``` 0: input, "cudatests.cu", cuda, (host-cuda) 1: preprocessor, {0}, cuda-cpp-output, (host-cuda) 2: compiler, {1}, ir, (host-cuda) 3: input, "cudatests.cu", cuda, (device-cuda, sm_35) 4: preprocessor, {3}, cuda-cpp-output, (device-cuda, sm_35) 5: compiler, {4}, ir, (device-cuda, sm_35) 6: backend, {5}, assembler, (device-cuda, sm_35) 7: assembler, {6}, object, (device-cuda, sm_35) 8: offload, "device-cuda (nvptx64-nvidia-cuda:sm_35)" {7}, object 9: offload, "device-cuda (nvptx64-nvidia-cuda:sm_35)" {6}, assembler 10: input, "cudatests.cu", cuda, (device-cuda, sm_37) 11: preprocessor, {10}, cuda-cpp-output, (device-cuda, sm_37) 12: compiler, {11}, ir, (device-cuda, sm_37) 13: backend, {12}, assembler, (device-cuda, sm_37) 14: assembler, {13}, object, (device-cuda, sm_37) 15: offload, "device-cuda (nvptx64-nvidia-cuda:sm_37)" {14}, object 16: offload, "device-cuda (nvptx64-nvidia-cuda:sm_37)" {13}, assembler 17: linker, {8, 9, 15, 16}, cuda-fatbin, (device-cuda) 18: offload, "host-cuda (powerpc64le-unknown-linux-gnu)" {2}, "device-cuda (nvptx64-nvidia-cuda)" {17}, ir 19: backend, {18}, assembler 20: assembler, {19}, object 21: input, "cuda", object 22: input, "cudart", object 23: linker, {20, 21, 22}, image ``` The changes in this patch pass the existent regression tests (keeps the existent functionality) and resulting binaries execute correctly in a Power8+K40 machine.

Summary: Currently our handling of CUDA architectures is scattered all around clang. This patch centralizes it.

2016-01-14[CUDA] Invoke ptxas and fatbinary during compilation.Justin Lebar1-1/+1
Summary: Previously we compiled CUDA device code to PTX assembly and embedded that asm as text in our host binary. Now we compile to PTX assembly and then invoke ptxas to assemble the PTX into a cubin file. We gather the ptx and cubin files for each of our --cuda-gpu-archs and combine them using fatbinary, and then embed that into the host binary. Adds two new command-line flags, -Xcuda_ptxas and -Xcuda_fatbinary, which pass args down to the external tools.

2015-11-17[CUDA] use -aux-triple to pass target triple of opposite side of compilationArtem Belevich1-7/+4
Clang needs to know target triple for both sides of compilation so that preprocessor macros and target builtins from both sides are available. This change augments Compilation class to carry information about toolchains used during different CUDA compilation passes and refactors BuildActions to use it when it constructs CUDA jobs.

2014-12-21Reapply "Change -save-temps to emit unoptimized bitcode files."Bob Wilson1-0/+7
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. Based in part on a patch by Steven Wu. rdar://problem/18909437 llvm-svn: 224688

This reverts commit r224503. It broke compilation of fortran through the Clang driver. Previously `clang -c t.f` would invoke `gcc t.f` and `clang -cc1as`, but now it tries to call `clang -cc1 t.f` which fails for obvious reasons. llvm-svn: 224546

2014-08-29unique_ptrify Driver Action handlingDavid Blaikie1-34/+33
It hits a limit when we reach ActionList, which is used for dynamic conditional ownership, so we lose type safety there. This did expose at least one caller "lying" about ownership (passing ownership to an Action, then updating the Action to specify that it doesn't actually own the thing that was passed) - changing this to unique_ptr just makes that oddity more obvious. llvm-svn: 216713
