# vim: set ft=conf:
# This file details the human readable formats of MIPS bytecodes.
#
# These format records are used by mipsgen to generate formatted
# printing statements to translate opcodes into human readable disassembly
# for output.
#
# The formats come from "MIPS32 Architecture For Programmers
# Volume II: The MIPS32 Instruction Set".
#
# See MIPS_Vol2.pdf p34
# See scripts/mipsgen.rb
# See disasm/c/mipsdis.c
# See tables/field_format.txt
# The first column contains the mnemonic.
# The second column contains opcode arguments, delimited by a comma.
#
# The opcode arguments must match entries in tables/field_format.txt
