# vim: set ft=conf:
# This file details the specific format and extra decoding metadata required to
# output an opcode field as human readable text.
#
# This data is used by mipsgen to build both the format string for a printf
# statement, as well as gather the arguments for it.
#
# The formats come from "MIPS32 Architecture For Programmers
# Volume II: The MIPS32 Instruction Set".
#
# See MIPS_Vol2.pdf p34
# See tables/asm_format.txt
# See scripts/mipsgen.rb
# See disasm/c/mipsdis.c
# The first column contains the field name, used by the code generator to
# extract data from an opcode.
# The second column contains the printf format.
# The third column denotes whether the PC is required when extracting data from an opcode, this is used for jump and branch type instructions.
