9.28 MIPS Dependent Features

GNU as 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 MIPS RISC Architecture, by Kane and Heindrich (Prentice-Hall). For an overview of MIPS assembly conventions, see “Appendix D: Assembly Language Programming” in the same work.
