+ Add missing cuda_profiler_api.h to hip/hip_profile.h transformation.
NOTE: HIP Profiler API is under development. This is NOT WORKING example.
TODO: Find out a way to generate HIP_SCOPED_MARKER, HIP_BEGIN_MARKER, HIP_END_MARKER, declared in hip/hip_profile.h in particular place (signatures are to obtain).
+ Only a generation of transformation map of CUDA entities is implemented.
+ 2 hipify-clang options are added: -python, -o-python-map-dir.
+ Explicitly set -roc option for cuda_to_hip_mappings.py generation.
+ Generated file already might be used by pytorch team.
+ Only a generation of transformation map of CUDA entities supported by HIP is implemented.
+ 3 hipify-clang options are added: -perl, -o-perl-map, -o-perl-map-dir.
+ OptionsParser mode is changed from OneOrMore to Optional to support hipify-perl generation without actual hipification.
+ Add explicit control of source files specification absence in case of no perl generation.
+ Fix the error in cmake: clang 8.0.0 supports CUDA 10.0, not 10.1; only trunk clang 9.0.0 supports CUDA 10.1.
+ Update Readme:
1. clang's bug 36384 is gone, so latest stable release for Linux is clang 8.0.0, which supports CUDA up to 10.0;
2. update dependencies, testing and building notes.
+ CUDNN_API_supported_by_HIP.md update
+ CUDA_Runtime_API_functions_supported_by_HIP.md update
+ libraryPropertyType_t is moved to Runtime
+ test update
+ for all CUDA versions starting from 7.0
+ add missing functions
+ sync with HIP
+ update CUDA_Runtime_API_functions_supported_by_HIP.md
+ update affected tests
+ fix typos
+ formatting, annotating
+ Always check for existence any file or dir, first of all, because real_path and make_absolute differ: real_path additionally performs access on file/dir.
+ Relative path routines in source files implemented similarly to dirs.
+ Error handling improvements.
+ '-D' might be set as hipify-clang option (before separator '--' or without specifying separator at all);
+ '-D' as a clang option might be specified as well (after options separator '--');
+ All defines specified as hipify-clang defines (before options separator '--') will be set after clang's ones and will redefine the same clang's ones.
+ '-I' might be set as hipify-clang option (before separator '--' or without specifying separator at all);
+ '-I' as a clang option might be specified as well (after options separator '--').
+ Append '--' to the end of hipify-clang options in case of its absence.
[Reason]
+ Avoid the necessity for the user in JSON compilation database specification.
Otherwise:
Error while trying to load a compilation database:
Could not auto-detect compilation database for file "test.cu"
Though the hipification will be performed correctly without JSON database.
Repeats clang's '--cuda-path' option.
[Reason]
In case of absence of any other clang's options setting '-cuda-path' allows not to specify separator '--' before clang's '--cuda-path'.
+ Tests and scripts are updated accordingly.
hipify-clang could be built by Visual Studio 14 2015 or higher.
[Reason]
hipify-clang contains c++14 features which are not supported even by the latest VS 2013 and the Platform Toolset "Visual C++ Compiler Nov 2013 CTP".
Header files in those dirs are an integral part of clang, which includes wrapper headers for CUDA.
There is no need in checking those dirs.
[Reasons]
1. clang will not take into account empty or irrelevant include dirs;
2. Packages for different clang versions will have different header files in the above dirs.
[Reasons]
+ We don't compile kernel code at least for now as HIP kernel syntax is almost equal CUDA's;
+ clang always includes PTX in its binaries, so e.g. a binary compiled with --cuda-gpu-arch= would be forwards-compatible with e.g. sm_35 GPUs.
+ Due to latest Windows SDK implementation based on c++14 features, '-std+c++14' is a must;
+ Doesn't affect older versions of MSVC 2017, 2015 (the latest supported is MSVC 2015);
+ On linux still '-std=c++11' is a must;
+ Exclude '-std=' from lit config.
[Reasons]
+ File is opened further by clang
+ There is a regression with LLVM 5.x, when system error occurs: temporary file couldn't be renamed - permission denied.
