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.
+ 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.
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.
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.
+ 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
+ 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
+ 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
+ for all CUDA versions
+ add missing types
+ fix typos
+ sync with HIP
+ update CUDA_Driver_API_functions_supported_by_HIP.md
+ formatting, annotating
+ StringRef issue, which is finally moved to LLVM from Clang
+ Renamed getBeginLoc() and getEndLoc() resolution for Expr and TypeLoc classes
+ Support all the previous LLVM versions via LLVCompat
+ for all CUDA versions up to 10.0
+ add missing types
+ fix typos
+ sync with HIP
+ sync with CUDA Driver API
+ update CUDA_Runtime_API_functions_supported_by_HIP.md
+ update CUDA Driver API map accordingly
+ update CUDA_Driver_API_functions_supported_by_HIP.md
+ formatting, annotating
[Reasons]
+ Simplify the support
+ Optimize compilation and code generation time
[Additionally]
+ Update minimum required version of cmake
+ Fix MSVC compile options force update
+ for all CUDA versions
+ add missing types
+ fix typos
+ sync with HIP
+ update CUDA_Driver_API_functions_supported_by_HIP.md
+ formatting, annotating
Tested with CUDA 8.0, 9.0, 9.1 and 9.2.
Only 8.0 works with LLVM 7.0, due to the changes in LLVM trunc since released 6.0, which works fine with CUDA 8.0 and 9.0.
So, nothing to do in hipify-clang, hope that all the CUDA 9.x related issues will be fixed in 7.0 release.
