This avoids polluting the global namespace with a non-prefixed macro and makes it obvious in the call sites that we return. Semi-automatic conversion using, e.g., sed -i 's/GET_REGL(/return gdb_get_regl(mem_buf, /g' target-*/gdbstub.c followed by manual tweaking for sparc's GET_REGA() and Coding Style.
