Introduce support for PTX's mbarrier.inval .
Contiunation of D151334
update
Same comment as in https://reviews.llvm.org/D151334 on the pointer type.
rebase
add i64 pointer
You missed a spot :).
This should be LLVM_i64ptr, right?
With LLVM_i64ptr being:
def LLVM_i64ptr : LLVM_IntPtrBase<64>
I.e., no addrspace specifier. To match:
def llvm_i64ptr_ty : LLVMPointerType<llvm_i64_ty>; // i64*
