[libomptarget] Harmonize emitting CUDA errors and general debug messages.

2019-08-05T19:12:10+00:00

Ensures that CUDA fail reasons (such as "No CUDA-capable device detected") are printed together with libomptarget's debug message (e.g. "Error when setting CUDA context"). Previously, the former was printed only in CMAKE_BUILD_TYPE=Debug builds while the latter was enabled by LIBOMPTARGET_ENABLE_DEBUG. With this change, also only call cuGetErrorString when the error will be printed. Suggested-by: Ye Luo Differential Revision: https://reviews.llvm.org/D65687 llvm-svn: 367910

[OpenMP][libomptarget] Add support for declare target to clause under unified memory

2019-06-19T15:48:10+00:00

Summary: This patch adds support for handling variables under the: ``` #pragma omp declare target to() ``` clause when the ``` #pragma omp requires unified_shared_memory ``` is used. The address of the host variable is copied into the device pointer just like for the declare target link case.

[OpenMP][libomptarget] Enable usage of unified memory for declare target link variables

2019-06-04T15:05:53+00:00

Summary: This patch enables the usage of a host variable on the device for declare target link variables when unified memory is available.

Update more file headers across all of the LLVM projects in the monorepo

2019-01-19T10:56:40+00:00

to reflect the new license. These used slightly different spellings that defeated my regular expressions. 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. llvm-svn: 351648

[libomptarget][CUDA] Use cuDeviceGetAttribute, NFCI.

2018-09-04T15:13:28+00:00

cuDeviceGetProperties has apparently been deprecated since CUDA 5.0. Nvidia started using annotations only in CUDA 9.2, so nobody noticed nor cared before. The new function returns the same values, tested with a P100. Differential Revision: https://reviews.llvm.org/D51624 llvm-svn: 341372

[OPENMP, NVPTX] Support several images in the executable.

2018-07-09T17:46:55+00:00

Summary: Currently Cuda plugin supports loading of the single image, though we may have the executable with the several images, if it has target regions inside of the dynamically loaded library. Patch allows to load multiple images. Reviewers: grokos Subscribers: guansong, openmp-commits, kkwli0 Differential Revision: https://reviews.llvm.org/D49036 llvm-svn: 336569

[CMake] Unify install path for libraries

2018-05-25T15:56:41+00:00

Introduce OPENMP_INSTALL_LIBDIR and use in all install() commands. This also fixes installation of libomptarget-nvptx that previously didn't honor {OPENMP,LLVM}_LIBDIR_SUFFIX. Differential Revision: https://reviews.llvm.org/D47130 llvm-svn: 333284

[OpenMP] Use LIBOMPTARGET_DEVICE_RTL_DEBUG env var to control debug messages on the device side

2018-05-04T19:29:28+00:00

Summary: Enable the device side debug messages at compile time, use env var to control at runtime. To achieve this, an environment data block is passed to the device lib when it is loaded. By default, the message is off, to enable it, a user need to set LIBOMPDEVICE_DEBUG=1.
