We now have several options that apply for both libraries and they shouldn't be documented in multiple files. When already merging the two Build_With_CMake.txt documents, convert them to reStructuredText which is used for all of LLVM's documentation.

README for the LLVM* OpenMP* Offloading Runtime Library (libomptarget)
|
|
======================================================================
|
|
|
|
How to Build the LLVM* OpenMP* Offloading Runtime Library (libomptarget)
|
|
========================================================================
|
|
In-tree build:
|
|
|
|
$ cd where-you-want-to-live
|
|
Check out openmp (libomptarget lives under ./libomptarget) into llvm/projects
|
|
$ cd where-you-want-to-build
|
|
$ mkdir build && cd build
|
|
$ cmake path/to/llvm -DCMAKE_C_COMPILER=<C compiler> -DCMAKE_CXX_COMPILER=<C++ compiler>
|
|
$ make omptarget
|
|
|
|
Out-of-tree build:
|
|
|
|
$ cd where-you-want-to-live
|
|
Check out openmp (libomptarget lives under ./libomptarget)
|
|
$ cd where-you-want-to-live/openmp/libomptarget
|
|
$ mkdir build && cd build
|
|
$ cmake path/to/openmp -DCMAKE_C_COMPILER=<C compiler> -DCMAKE_CXX_COMPILER=<C++ compiler>
|
|
$ make
|
|
|
|
For details about building, please look at README.rst in the parent directory.

Architectures Supported
|
|
=======================
|
|
The current library has been only tested in Linux operating system and the
|
|
following host architectures:
|
|
* Intel(R) 64 architecture
|
|
* IBM(R) Power architecture (big endian)
|
|
* IBM(R) Power architecture (little endian)
|
|
* ARM(R) AArch64 architecture (little endian)
|
|
|
|
The currently supported offloading device architectures are:
|
|
* Intel(R) 64 architecture (generic 64-bit plugin - mostly for testing purposes)
|
|
* IBM(R) Power architecture (big endian) (generic 64-bit plugin - mostly for testing purposes)
|
|
* IBM(R) Power architecture (little endian) (generic 64-bit plugin - mostly for testing purposes)
|
|
* ARM(R) AArch64 architecture (little endian) (generic 64-bit plugin - mostly for testing purposes)
|
|
* CUDA(R) enabled 64-bit NVIDIA(R) GPU architectures
|
|
|
|

Front-end Compilers that work with this RTL
|
|
===========================================
|
|
|
|
The following compilers are known to do compatible code generation for
|
|
this RTL:
|
|
- clang (from https://github.com/clang-ykt )
|
|
- clang (development branch at http://clang.llvm.org - several features still
|
|
under development)
|
|
|
|
-----------------------------------------------------------------------

Notices
|
|
=======
|
|
This library and related compiler support is still under development, so the
|
|
employed interface is likely to change in the future.
