* [COFF, ARM64] Align global symbol by size for ARM64 MSVC ABITom Tan2019-05-021-1/+1
| | | | | | | | | | | | | | | | | | According to alignment section in below ARM64 ABI document, MSVC could increase alignment of global data based on its total size. Clang doesn't do this. Compile the same symbol into different alignments by Clang and MSVC could cause link error because some instruction encodings, like 64-bit LDR/STR with immediate, require the target to be 8 bytes aligned, and linker could choose code stream with such LDR/STR instruction from MSVC and 4 bytes aligned data from Clang into final image, which actually cannot be linked together (see https://bugs.llvm.org/show_bug.cgi?id=41506 for more details). https://docs.microsoft.com/en-us/cpp/build/arm64-windows-abi-conventions?view=vs-2019#alignment Differential Revision: https://reviews.llvm.org/D61225 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@359744 91177308-0d34-0410-b5e6-96231b3b80d8
* [CUDA] Implemented _[bi]mma* builtins.Artem Belevich2019-04-251-0/+2
| | | | | | | | | | | | | | | | These builtins provide access to the new integer and sub-integer variants of MMA (matrix multiply-accumulate) instructions provided by CUDA-10.x on sm_75 (AKA Turing) GPUs. Also added a feature for PTX 6.4. While Clang/LLVM does not generate any PTX instructions that need it, we still need to pass it through to ptxas in order to be able to compile code that uses the new 'mma' instruction as inline assembly (e.g used by NVIDIA's CUTLASS library https://github.com/NVIDIA/cutlass/blob/master/cutlass/arch/mma.h#L101) Differential Revision: https://reviews.llvm.org/D60279 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@359248 91177308-0d34-0410-b5e6-96231b3b80d8
* 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

* [CUDA] Added partial support for CUDA-9.1Artem Belevich2018-01-301-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clang can use CUDA-9.1 now, though new APIs (are not implemented yet. The major change is that headers in CUDA-9.1 went through substantial changes that started in CUDA-9.0 which required substantial changes in the cuda compatibility headers provided by clang. There are two major issues: * CUDA SDK no longer provides declarations for libdevice functions. * A lot of device-side functions have become nvcc's builtins and CUDA headers no longer contain their implementations. This patch changes the way CUDA headers are handled if we compile with CUDA 9.x. Both 9.0 and 9.1 are affected. * Clang provides its own declarations of libdevice functions. * For CUDA-9.x clang now provides implementation of device-side 'standard library' functions using libdevice. This patch should not affect compilation with CUDA-8. There may be some observable differences for CUDA-9.0, though they are not expected to affect functionality. Tested: CUDA test-suite tests for all supported combinations of: CUDA: 7.0,7.5,8.0,9.0,9.1 GPU: sm_20, sm_35, sm_60, sm_70 Differential Revision: https://reviews.llvm.org/D42513 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@323713 91177308-0d34-0410-b5e6-96231b3b80d8
* [OpenMP] Show error if VLAs are not supportedJonas Hahnfeld2017-11-181-0/+1
| | | | | | | | | | | | | | Some target devices (e.g. Nvidia GPUs) don't support dynamic stack allocation and hence no VLAs. Print errors with description instead of failing in the backend or generating code that doesn't work. This patch handles explicit uses of VLAs (local variable in target or declare target region) or implicitly generated (private) VLAs for reductions on VLAs or on array sections with non-constant size.

* [CUDA] Added rudimentary support for CUDA-9 and sm_70.Artem Belevich2017-09-071-0/+2
| | | | | | | | | | | | | For now CUDA-9 is not included in the list of CUDA versions clang searches for, so the path to CUDA-9 must be explicitly passed via --cuda-path=. On LLVM side NVPTX added sm_70 GPU type which bumps required PTX version to 6.0, but otherwise is equivalent to sm_62 at the moment.

* Break up Targets.cpp into a header/impl pair per target type[NFCI]Erich Keane2017-07-211-0/+196
Targets.cpp is getting unwieldy, and even minor changes cause the entire thing to cause recompilation for everyone. This patch bites the bullet and breaks it up into a number of files. I tended to keep function definitions in the class declaration unless it caused additional includes to be necessary. In those cases, I pulled it over into the .cpp file. Content is copy/paste for the most part, besides includes/format/etc. Differential Revision: https://reviews.llvm.org/D35701 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@308791 91177308-0d34-0410-b5e6-96231b3b80d8
