Currently Clang uses default address space (0) to represent private address space for OpenCL in AST. There are two issues with this: Multiple address spaces including private address space cannot be diagnosed. There is no mangling for default address space. For example, if private int* is emitted as i32 addrspace(5)* in IR. It is supposed to be mangled as PUAS5i but it is mangled as Pi instead. This patch attempts to represent OpenCL private address space explicitly in AST. It adds a new enum LangAS::opencl_private and adds it to the variable types which are implicitly private: automatic variables without address space qualifier function parameter pointee type without address space qualifier (OpenCL 1.2 and below) Differential Revision: https://reviews.llvm.org/D35082 llvm-svn: 315668
