foo .req w0
ip0, ip1, lr and fp are automatically defined to alias to X16, X17, X30 and X29 respectively.
reqdirective. For example:

An error occurs if the name is undefined. Note - this pseudo op can be used to delete builtin in register name aliases (eg 'w0'). This should only be done if it is really necessary.
.xworddirective produces 64 bit values. This is the same as the
