Yaxun (Sam) Liu	1b978ddba0	[CUDA][HIP][OpenMP] Emit deferred diagnostics by a post-parsing AST travese ... This patch removes the explicit call graph for CUDA/HIP/OpenMP deferred diagnostics generated during parsing since it is error prone due to incomplete information about function declarations during parsing. In stead, this patch does a post-parsing AST traverse and emits deferred diagnostics based on the use graph implicitly generated during the traverse.

Yaxun Liu	229c78d3a5	[CUDA][HIP] Fix host/device check with -fopenmp ... CUDA/HIP program may be compiled with -fopenmp. In this case, -fopenmp is only passed to host compilation to take advantages of multi-threads computation. CUDA/HIP and OpenMP both use Sema::DeviceCallGraph to store functions to be analyzed and remove them once they decide the function is sure to be emitted. CUDA/HIP and OpenMP have different functions to determine if a function is sure to be emitted. To check host/device correctly for CUDA/HIP when -fopenmp is enabled, there needs a unified logic to determine whether a function is to be emitted. The logic needs to be aware of both CUDA and OpenMP logic. Differential Revision: https://reviews.llvm.org/D67837 llvm-svn: 374263	2019-10-09 23:54:10 +00:00
