+ Update *.md docs and hipify-perl accordingly
[Reason]
Starting with CUDA 10.1 all error codes are merged between Driver and RT APIs
[ToDo]
Do the same merge in HIP API as there is no need in distinguishing return codes by API
+ Add a corresponding test kernel_launch_01.cu
+ Add isBefore() check to avoid crash on Replacement with negative length
TODO:
+ Compatibility with former LLVM versions
+ More complicated kernel launch tests
By implicit unconditional passing -fno-delayed-template-parsing option (which appeared in LLVM 3.8.0, thus doesn't need compatibility wrapping) to hipify-clang.
[Reason] To parse uncalled template functions otherwise they are not parsed without calling, thus not hipified.
Affects cub_03.cu test, which has uncalled global template function.
+ Add one matcher (will be more)
+ Update Maps and Statistics
+ Add cub_01.cu unit test
+ Update lit harness to support standalone CUB
+ Update README.md
+ Update hipify-perl (only CUB header is supported for now)
[IMPORTANT]
clang (and hipify-clang) works correctly only with official NVLabs version on GitHub.
Compilation of CUB from official CUDA release has conflicts with THRUST.
Thus, to compile CUB sources, option "-I" should be specified to the cloned CUB from NVLAB on GitHub.
Added new memory API's hipMemAllocPitch, hipMemAllocHost, hipMemsetD16, hipMemsetD16Async, hipMemsetD8Async
Modified to support all scenarios hipMemcpyParam2DAsync, hipMemcpyParam2D.
+ Get rid of --o-perl-map option for Perl output filename: the output name now is always hipify-perl
+ Option --o-perl-map-dir renamed to --o-hipify-perl-dir
Cmd example for generating hipify-perl script to the particular directory:
hipify-clang -perl --o-hipify-perl-dir=../../bin
+ hipify-perl script is entirely generated by hipify-clang under an option -perl now
+ hipify-perl still has correctness gaps comparing to hipify-clang: they will be eliminated AMAP further
[REASON]
1. hip-clang is fine with the templated kernel launch, brackets are unneeded: HIP_KERNEL_NAME(...) __VA_ARGS__
2. HCC is not, thus: HIP_KERNEL_NAME(...) (__VA_ARGS__)
[TODO] Clean-up entirely kernel name wrapping when HCC is finally obsolete.
+ Update perl generation, hipify-perl, and affected tests accordingly.
+ Perl part of [#1458]
+ Affected functions: hipFuncSetCacheConfig, hipFuncGetAttributes
+ Implement function generateHostFunctions() in hipify-clang for that purposes
+ Update hipify-perl accordingly
+ Merge of cudaSymbolFuncCall and cudaReinterpretCastArgFuncCall matchers into a single cudaHostFuncCall matcher
+ More const std::string declarations
+ Formatting
+ Affected functions: hipFuncSetCacheConfig, hipFuncGetAttributes
+ Add a corresponding Matcher cudaReinterpretCastArgFuncCall
+ Add reinterpret_cast.cu test
TODO: Do the same for hipify-perl
