+ CUDA_Driver_API_functions_supported_by_HIP.md update.
+ Initial update of HIPIFY with CUDA driver API functions:
1.Error Handling, 2.Initialization, 3.Version Management, 5-6.Device Management, 7.Primary Context, 8-9.Context, 10.Module Management, 11.Memory Management.
+ Sync HIP functions against CUDA Driver and Runtime API functions.
+ Typo fixes.
ToDo: 12-30 modules of CUDA Driver API.
+ Memory advise values
+ Memory Range Attributes
+ P2P Attributes
P.S.
There is no any new changes in CUDA Driver API 8.0.61 Data structures since 8.0.44.
https://github.com/GPUOpen-ProfessionalCompute-Tools/HIP/issues/80
Example from CUDA 8.0.44 sample (CUDASamples\0_Simple\matrixMulDrv\matrixMulDrv.cpp):
CUjit_option *jitOptions = new CUjit_option[jitNumOptions];
where CUjit_option is enum, should be:
hipJitOption *jitOptions = new hipJitOption[jitNumOptions];
https://github.com/GPUOpen-ProfessionalCompute-Tools/HIP/issues/81
1. Do not use JIT options on HCC path, call hipModuleLoadData instead.
2. NVCC path is unchanged, to call cuModuleLoadDataEx with all options.
3. Get rid of manual hipification, based on #ifdef #else for NVCC/HIP.
4. Update documentation accordingly.
Some Clang tooling functions return std::string, some return StringRef. Assigning of returning std::string to StringRef variables leads to garbage in it.
DEBUG build is always affected.
+ Update CUDA_Driver_API_functions_supported_by_HIP.md.
+ Final update of HIPIFY with CUDA driver data types.
[TODO] Syncing HIPIFY and HIP by CUDA Driver API functions.
https://github.com/GPUOpen-ProfessionalCompute-Tools/HIP/issues/71
[Solution]
getUnqualifiedType for enumConstantDecl's type is added, except ordinary enum declarations (w/o typedef).
[ToDo]
Find more appropriate way of distinguishing redefined enum declarations and ordinary ones.
+ Introduce CUDA_Driver_API_functions_supported_by_HIP.md.
+ Initial update of HIPIFY with CUDA driver data types.
+ Initial sync HIP types against CUDA Driver and Runtime API types.
+ Typo fixes.
+ all Cuda 7.5 RT API enum values are synced.
+ a few missing functions are added.
+ CONV_EXEC type is added for Execution control functions and data types.

[Bug]
Access violation in cudaStructVar matcher.
StringRef name = structVar->getType()
->getAsStructureType()
->getDecl() // <--- Access Violation
->getNameAsString();
[Solution]
Add isStructureType() check before getting type as Struct.
[ToDo]
Find case-studies for that StructVar matcher with types other than Struct.
CUstream_st -> hipStream_t *
CUevent_st -> hipEvent_t * (fixed, was -> hipEvent_t)
Warning:
[HIPIFY] warning: the following reference is not handled: 'CUstream_st' [struct var ptr]. (thrust/examples/cuda/async_reduce.cu)
[Explanation]
Narrow cudaKernelCallExpr matcher to isExpansionInMainFile() - to the file being actually converted (without system includes).
But as for Thrust, there are *.inl files, which are nevertheless being expanded in main file.
These files contain cuda kernel launches, which are not converted successfully by hipify, for instance:
thrust/system/cuda/detail/detail/launch_closure.inl:98:23.
[ToDo]
File a bug on cudaKernelCallExpr matcher for conversion error (thrust\examples\cuda\<any cu example>).
All are marked as HIP_UNSUPPORTED.
IMPORTANT:
1. libraryPropertyType_t has no cuda prefix. => TO_DO: new matcher is needed.
2. all libraries (cublas, cufft, cusolver, cusparse, nvgraph) have started to use these types (since 8.0).
