<p><small>GNU</small> <code>as</code> for MIPS architectures supports several
different MIPS processors, and MIPS ISA levels I through V, MIPS32,
and MIPS64.  For information about the MIPS instruction set, see
<cite>MIPS RISC Architecture</cite>, by Kane and Heindrich (Prentice-Hall).
For an overview of MIPS assembly conventions, see &ldquo;Appendix D:
Assembly Language Programming&rdquo; in the same work.
