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.
[ROCm/clr commit: e9589e3330]
[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.
[ROCm/clr commit: 6f6228cf36]
+ 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.
[ROCm/clr commit: b24e89b40f]
[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.
[ROCm/clr commit: 8f415def6f]
Option -o-dir for output directory:
+ if not specified source file(s) directory is used;
+ creates the directory if the directory doesn't exist (only one level in a tree);
+ if -o and -o-dir both are specified the hipified file is placed to "-o-dir" + "-o";
+ reports an error in case of a wrong directory specified, in case of necessity of creating a tree of subfolders, or in case of a filename specified.
[ROCm/clr commit: c65338fbf7]
1. Option -temp-dir for temporary directory:
+ if not specified system temp is used;
+ creates the directory if the directory doesn't exist (only one level in a tree);
+ reports an error in case of a wrong directory specified, in case of necessity of creating a tree of subfolders, or in case of a filename specified.
2. Option -save-temps for preserving temporary files:
+ if specified temporary files are not being deleted from system temps and user temps as well.
3. Work with files in terms of calculated absolute paths by collapsing all '.' and '..' patterns, resolving symlinks and expanding '~' expression to the user's home directory:
+ to produce correct include paths;
+ to avoid possible errors on file routines.
[ROCm/clr commit: 7cac7dbfea]
+ Do temp file copying instead of renaming
+ Replace all file routine functions with LLVM's
+ Do not output hipified file in case of errors
[ROCm/clr commit: cb598445f5]
+ Files are not being placed near original source before hipification anymore, system tmp is used for them now.
+ Additional include (-I) to absolute original source dir is added
+ Partially implements #812
+ Tested on windows/linux, single/multiple inputs, with and without includes to user header files
[ROCm/clr commit: 1180928408]
+ Signs of the converted file are extended
+ Total converted lines and total elapsed time are fixed
+ Zero rates are excluded from statistics
[ROCm/clr commit: 1e30cd3ea7]
+ Just do load_config for lit.site.cfg earlier in lit.cfg to get initialized cuda_version
+ Remove lit.cfg.in for CMake variables substitution
+ Return back lit.cfg
+ Exclude CUDA 9.0 tests if CUDA < 9.0
+ Report CUDA version before running tests
[ROCm/clr commit: a5c66018b6]
+ Add lit.cfg.in for CMake variables substitution to now generated lit.cfg
+ Exclude lit.cfg
+ Exclude CUDA 9.0 tests if CUDA < 9.0
+ Report CUDA version before running tests
[ROCm/clr commit: 2b01f1eb6f]
+ Option '-roc' is added to translate to ROCm instead of HIP
+ Update hipification mechanism accordingly
+ Populate all translation maps with additional field for ROCm identifiers
+ There are 4 degrees of CUDA support now: full support, only by HIP, only by ROCm, unsupported
[ROCm/clr commit: 747eb2c11c]
+ cuSPARSE is supported up to CUDA 10.0
+ cuSPARSE_08 test (CUDA 10.0)
+ update CUSPARSE_API_supported_by_HIP.md
+ lit: add a rule for CUDA 10.0 tests excluding
