Add mapping for CUDA address spaces for HIP to SPIR-V translation. This change allows HIP device code to be emitted as valid SPIR-V by mapping unqualified pointers to generic address space and by mapping __device__ and __shared__ AS to their equivalent AS in SPIR-V (CrossWorkgroup and Workgroup, respectively). Cuda's __constant__ AS is handled specially. In HIP unqualified pointers (aka "flat" pointers) can point to __constant__ objects. Mapping this AS to ConstantMemory would produce to illegal address space casts to generic AS. Therefore, __constant__ AS is mapped to CrossWorkgroup. Patch by linjamaki (Henry Linjamäki)!

//===----------------------------------------------------------------------===// // C Language Family Front-end //===----------------------------------------------------------------------===// Welcome to Clang. This is a compiler front-end for the C family of languages (C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM compiler infrastructure project. Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source-level tools. One example of this is the Clang Static Analyzer. If you're interested in more (including how to build Clang) it is best to read the relevant web sites. Here are some pointers: Information on Clang: http://clang.llvm.org/ Building and using Clang: http://clang.llvm.org/get_started.html Clang Static Analyzer: http://clang-analyzer.llvm.org/ Information on the LLVM project: http://llvm.org/ If you have questions or comments about Clang, a great place to discuss them is on the Clang development mailing list: http://lists.llvm.org/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
