ptypeN is functionally the same as typeN except that it informs the SelectionDAG importer that an operand should be treated as a pointer even if it was written as iN. This is important for patterns that use iN instead of iPTR to represent pointers. E.g.: (set GPR64:$dst, (load GPR64:$addr)) Previously, this was handled as a hardcoded special case for the appropriate operands to G_LOAD and G_STORE. llvm-svn: 318574
