BSD 4_3_Tahoe release

## Copyright (c) 1982 Regents of the University of California
## @(#)instrs 4.9 6/30/83
##
## Robert R. Henry
## University of California, Berkeley
## Berkeley, CA
## February 6, 1982
##
## Updated 19 May 83 to include the page number in the
## architecture reference manual (1981 edition) the instruction
## is documented on, and to enumerate the instructions in the same
## order as the reference manual does.
##
## THIS FILE IS BOTH AN AWK SCRIPT AND THE DATA
##
## Instruction definitions for the TAHOE
##
## This file is processed by an awk script, viz:
## (echo "FLAVOR AS"; cat instrs) | awk -f instrs > as.instrs
## (echo "FLAVOR ADB"; cat instrs) | awk -f instrs > as.instrs
## (echo "FLAVOR SDB"; cat instrs) | awk -f instrs > as.instrs
## (echo "FLAVOR C2"; cat instrs) | awk -f instrs > c2.instrs
##
## The data in this file is shared between:
## as assembler
## c2 optimizer
## adb debugger
## sdb symbolic debugger
##
## The awk script reads itself, and produces macros understood
## by the appropriate consumer. The awk script determines how
## to interpret the file by looking for a line of the form:
## FLAVOR AS
## FLAVOR ADB (same as AS, but without pseudo instructions)
## FLAVOR SDB (same as ADB)
## FLAVOR C2 (radically different format for instructions)
## and proceeding accordingly. This line should be prepended to
## the front of this file.
##
## Lines starting with # are always comments to awk
## Lines starting with ## are always comments
## Lines starting with a single # are data lines, to be output.
##
## Empty lines are passed through
##
## field user(s) what
##
## $2 awk #: comment to awk
##
## $3 as, c2, adb instruction name
##
## $4 c2 instruction class
## $5 c2 instruction sub class
## HARD, TN1, TNX2, OP
##
## $6 as, adb opcode byte
##
## $7 as, adb number of arguments
## $8 as, adb 1st operand: access A,R,W,M,I,B
## $9 as, adb 1st operand: type, BWLQOFDGH
##
## $10 as, adb 2nd operand: access
## ...
##
##
## These are the definitions used in this file:
## instruction class (c2)
## understood only by c2. If it is HARD, the second field
## is ignored.
## instruction subclass: (c2)
## HARD paired with the class
## S single valued attribute to C2
## TN1 class + type of 1st operand
## TNX2 class + type of 1st and 2nd operand
## OP class + type of 1st operand and # of args
## default class + subclass
##
##
## code byte
## number of arguments
## Access type
## A for address, only in memory
## W for writing
## R for reading
## M for modifying
## B for branch displacement
## Data types
## B byte
## W word
## L long
## Q quad
## F f_float
## D d_float
##
## The order of instructions in this table is not critical;
## the clients take care of their own table construction and ordering.
## The instructions are grouped (more or less) into functional groups.
##
## The following is the awk program to interpret this table.
BEGIN{
flavor = AS;
##
## magic padding before the string for AS
## 4 bytes of 0's: seek position of the string
## 2 bytes, value 2, indicating core resident
## 2 bytes, value 0, length

Continuous source code history from original PDP-7 UNIX to FreeBSD 2, the first fully unencumbered FreeBSD release.
