[OpenMP] Improve search for libomptarget-nvptx When looking for the bclib Clang considered the default library path first while it preferred directories in LIBRARY_PATH when constructing the invocation of nvlink. The latter actually makes more sense because during development it allows using a non-default runtime library. So change the search for the bclib to start looking in directories given by LIBRARY_PATH. Additionally add a new option --libomptarget-nvptx-path= which will be searched first. This will be handy for testing purposes. Differential Revision: https://reviews.llvm.org/D51686 llvm-svn: 343230

[Clang][OpenMP Offload] Add new tool for wrapping offload device binaries This patch removes the remaining part of the OpenMP offload linker scripts which was used for inserting device binaries into the output linked binary. Device binaries are now inserted into the host binary with a help of the wrapper bit-code file which contains device binaries as data. Wrapper bit-code file is dynamically created by the clang driver with a help of new tool clang-offload-wrapper which takes device binaries as input and produces bit-code file with required contents. Wrapper bit-code is then compiled to an object and resulting object is appended to the host linking by the clang driver. This is the second part of the patch for eliminating OpenMP linker script (please see https://reviews.llvm.org/D64943). Differential Revision: https://reviews.llvm.org/D68166 llvm-svn: 374219

[OpenMP] Improve search for libomptarget-nvptx When looking for the bclib Clang considered the default library path first while it preferred directories in LIBRARY_PATH when constructing the invocation of nvlink. The latter actually makes more sense because during development it allows using a non-default runtime library. So change the search for the bclib to start looking in directories given by LIBRARY_PATH. Additionally add a new option --libomptarget-nvptx-path= which will be searched first. This will be handy for testing purposes. Differential Revision: https://reviews.llvm.org/D51686 llvm-svn: 343230

[OpenMP][Clang] Support for target math functions Summary: In this patch we propose a temporary solution to resolving math functions for the NVPTX toolchain, temporary until OpenMP variant is supported by Clang. We intercept the inclusion of math.h and cmath headers and if we are in the OpenMP-NVPTX case, we re-use CUDA's math function resolution mechanism.
