* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@351636 91177308-0d34-0410-b5e6-96231b3b80d8
* [Driver] Clean up tmp files when deleting Compilation objectsDavid Stenberg2018-05-311-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: In rL327851 the createUniqueFile() and createTemporaryFile() variants that do not return the file descriptors were changed to create empty files, rather than only check if the paths are free. This change was done in order to make the functions race-free. That change led to clang-tidy (and possibly other tools) leaving behind temporary assembly files, of the form placeholder-*, when using a target that does not support the internal assembler. The temporary files are created when building the Compilation object in stripPositionalArgs(), as a part of creating the compilation database for the arguments after the double-dash. The files are created by Driver::GetNamedOutputPath(). Fix this issue by cleaning out temporary files at the deletion of Compilation objects. This fixes https://bugs.llvm.org/show_bug.cgi?id=37091.

| | | | | | | | | | | | | | | Summary: This patch includes support for argument translation that is specific of a given offloading kind. Additionally, it implements the translation for OpenMP device kinds in the gcc tool chain.

* [CUDA][OpenMP] Add a generic offload action builderSamuel Antao2016-09-301-0/+6
| | | | | | | | | | | | | | | | | | | | | | Summary: This patch proposes a new class to generate and record action dependences related with offloading. The builder provides three main functionalities: - Add device dependences to host actions. - Add host dependence to device actions. - Register device top-level actions. The constructor of the builder detect the programming models that should be supported, and generates a specialized builder for each. If a new programming model is to be added in the future, only a new specialized builder has to be implemented. When the specialized builder is generated, it produces programming-model-specific diagnostics. A CUDA specialized builder is proposed in the patch that mostly consists of the partition of the current `buildCudaAction` by the three different functionalities.

* [CUDA][OpenMP] Create generic offload actionSamuel Antao2016-07-151-8/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [CUDA][OpenMP] Create generic offload toolchainsSamuel Antao2016-06-131-9/+53
| | | | | | | | | | | | | | | | | | | Summary: This patch introduces the concept of offloading tool chain and offloading kind. Each tool chain may have associated an offloading kind that marks it as used in a given programming model that requires offloading. It also adds the logic to iterate on the tool chains based on the kind. Currently, only CUDA is supported, but in general a programming model (an offloading kind) may have associated multiple tool chains that require supporting offloading. This patch does not add tests - its goal is to keep the existing functionality. This patch is the first of a series of three that attempts to make the current support of CUDA more generic and easier to extend to other programming models, namely OpenMP. It tries to capture the suggestions/improvements/concerns on the initial proposal in http://lists.llvm.org/pipermail/cfe-dev/2016-February/047547.html. It only tackles the more consensual part of the proposal, i.e.does not address the problem of intermediate files bundling yet.

| | | | | | | | | | | | | | | | Clang needs to know target triple for both sides of compilation so that preprocessor macros and target builtins from both sides are available.

* Move Compilation::PrintJob and PrintDiagnosticJob into Job::Print.Hans Wennborg2013-09-121-17/+0
| | | | | | | | | | | | | | | | | 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.

* Driver: Move Compilation::Execute to Driver::ExecuteCompilation.Daniel Dunbar2009-07-011-6/+6
| | | | | | | | | | - The Compilation is just a helper class, it shouldn't have that amount of logic in it. - No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74634 91177308-0d34-0410-b5e6-96231b3b80d8
* Driver: Improve diagnostics for failed commands.Daniel Dunbar2009-07-011-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Not all tools give good error messages, and sometimes the tool can fail w/o any error (for example, when signalled). - We suppress this message when the failing command is the compiler and it failed normally (exit code == 1), under the assumption that it gave a good diagnostic. For example, for a linker failure we now get: -- ddunbar@lordcrumb:tmp$ clang a.c b.c ld: duplicate symbol _x in /var/folders/cl/clrOX6SaG+moCeRKEI4PtU+++TI/-Tmp-/cc-bXYITq.o and /var/folders/cl/clrOX6SaG+moCeRKEI4PtU+++TI/-Tmp-/cc-6uK4jD.o clang: error: linker command failed with exit code 1 (use -v to see invocation) -- For a compiler crash we get: -- ddunbar@lordcrumb:tmp$ clang t.i Assertion failed: (CGT.getTargetData().getTypeAllocSizeInBits(STy) == RL.getSize()), function layoutStructFields, file CodeGenTypes.cpp, line 573. 0 clang-cc 0x0000000100f1f1f1 PrintStackTrace(void*) + 38 ... stack trace and virtual stack trace follow ... clang: error: compiler command failed due to signal 6 (use -v to see invocation) -- But for a regular compilation failure we get the usual: -- ddunbar@lordcrumb:tmp$ clang c.c c.c:1:6: error: invalid token after top level declarator int x ^ 1 diagnostic generated. -- - No test case, not amenable to non-executable testing. :/ - <rdar://problem/6945613> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74629 91177308-0d34-0410-b5e6-96231b3b80d8
* Driver: Prep for tool chain specific argument translation.Daniel Dunbar2009-03-251-9/+10
| | | | | | | | | | | | | | | | | - Lift ArgList to a base class for InputArgList and DerivedArgList. - This is not a great decomposition, but it does embed the translation into the type system, and keep things efficient for tool chains that don't want to do any translation. - No intended functionality change. Eventually I hope to get rid of tool chain specific translation and have each tool do the right thing, but for now this is the easiest way to match gcc precisely (which is good for testing). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67676 91177308-0d34-0410-b5e6-96231b3b80d8
