2 README for the LLVM* OpenMP* Runtime Library
3 ============================================
4
5How to Build Documentation
6==========================
7
8The main documentation is in Doxygen* format, and this distribution
9should come with pre-built PDF documentation in doc/Reference.pdf.
10However, an HTML version can be built by executing:
11
12% doxygen doc/doxygen/config
13
14in the runtime directory.
15
16That will produce HTML documentation in the doc/doxygen/generated
17directory, which can be accessed by pointing a web browser at the
18index.html file there.
19
20If you don't have Doxygen installed, you can download it from
21www.doxygen.org.

24How to Build the LLVM* OpenMP* Runtime Library
25==============================================
26In-tree build:
27
28$ cd where-you-want-to-live
29Check out openmp into llvm/projects
30$ cd where-you-want-to-build
31$ mkdir build && cd build
32$ cmake path/to/llvm -DCMAKE_C_COMPILER=<C compiler> -DCMAKE_CXX_COMPILER=<C++ compiler>
33$ make omp
34
35Out-of-tree build:
36
37$ cd where-you-want-to-live
38Check out openmp
39$ cd where-you-want-to-live/openmp/runtime
40$ mkdir build && cd build
41$ cmake path/to/openmp -DCMAKE_C_COMPILER=<C compiler> -DCMAKE_CXX_COMPILER=<C++ compiler>
42$ make
43
44For details about building, please look at README.rst in the parent directory.

58
59Supported RTL Build Configurations
60==================================
61
62Supported Architectures: IA-32 architecture, Intel(R) 64, and
63Intel(R) Many Integrated Core Architecture
64
65 ----------------------------------------------
66 | icc/icl | gcc | clang |
67--------------|---------------|----------------------------|
68| Linux* OS | Yes(1,5) | Yes(2,4) | Yes(4,6,7) |
69| FreeBSD* | No | No | Yes(4,6,7,8) |
70| OS X* | Yes(1,3,4) | No | Yes(4,6,7) |
71| Windows* OS | Yes(1,4) | No | No |
72------------------------------------------------------------
73
74(1) On IA-32 architecture and Intel(R) 64, icc/icl versions 12.x are
75 supported (12.1 is recommended).
76(2) GCC* version 4.7 is supported.
77(3) For icc on OS X*, OS X* version 10.5.8 is supported.
78(4) Intel(R) Many Integrated Core Architecture not supported.
79(5) On Intel(R) Many Integrated Core Architecture, icc/icl versions 13.0
80 or later are required.
81(6) Clang* version 3.3 is supported.
82(7) Clang* currently does not offer a software-implemented 128 bit extended
83 precision type. Thus, all entry points reliant on this type are removed
84 from the library and cannot be called in the user program. The following
85 functions are not available:
86 __kmpc_atomic_cmplx16_*
87 __kmpc_atomic_float16_*
88 __kmpc_atomic_*_fp
89(8) Community contribution provided AS IS, not tested by Intel.
90
91Supported Architectures: IBM(R) Power 7 and Power 8
