10: ## Updated 19 May 83 to include the page number in the
11: ## architecture reference manual (1981 edition) the instruction
12: ## is documented on, and to enumerate the instructions in the same
13: ## order as the reference manual does.
14: ##
15: ## THIS FILE IS BOTH AN AWK SCRIPT AND THE DATA
16: ##
17: ## Instruction definitions for the TAHOE
18: ##
19: ## This file is processed by an awk script, viz:
20: ## (echo "FLAVOR AS"; cat instrs) | awk -f instrs > as.instrs
21: ## (echo "FLAVOR ADB"; cat instrs) | awk -f instrs > as.instrs
22: ## (echo "FLAVOR SDB"; cat instrs) | awk -f instrs > as.instrs
23: ## (echo "FLAVOR C2"; cat instrs) | awk -f instrs > c2.instrs
24: ##
25: ## The data in this file is shared between:
26: ## as assembler
27: ## c2 optimizer
28: ## adb debugger
29: ## sdb symbolic debugger
30: ##
31: ## The awk script reads itself, and produces macros understood
32: ## by the appropriate consumer. The awk script determines how
33: ## to interpret the file by looking for a line of the form:
34: ## FLAVOR AS
35: ## FLAVOR ADB (same as AS, but without pseudo instructions)
36: ## FLAVOR SDB (same as ADB)
37: ## FLAVOR C2 (radically different format for instructions)
38: ## and proceeding accordingly. This line should be prepended to
39: ## the front of this file.
40: ##
41: ## Lines starting with # are always comments to awk
42: ## Lines starting with ## are always comments
43: ## Lines starting with a single # are data lines, to be output.
44: ##
45: ## Empty lines are passed through
46: ##
47: ## field user(s) what
48: ##
49: ## $2 awk #: comment to awk
50: ##
51: ## $3 as, c2, adb instruction name
52: ##
53: ## $4 c2 instruction class
54: ## $5 c2 instruction sub class
55: ## HARD, TN1, TNX2, OP
56: ##
57: ## $6 as, adb opcode byte
58: ##
59: ## $7 as, adb number of arguments
60: ## $8 as, adb 1st operand: access A,R,W,M,I,B
61: ## $9 as, adb 1st operand: type, BWLQOFDGH
62: ##
63: ## $10 as, adb 2nd operand: access
64: ## ...
65: ##
66: ##
67: ## These are the definitions used in this file:
68: ## instruction class (c2)
69: ## understood only by c2. If it is HARD, the second field
70: ## is ignored.
71: ## instruction subclass: (c2)
72: ## HARD paired with the class
73: ## S single valued attribute to C2
74: ## TN1 class + type of 1st operand
75: ## TNX2 class + type of 1st and 2nd operand
76: ## OP class + type of 1st operand and # of args
77: ## default class + subclass
78: ##
79: ##
80: ## code byte
81: ## number of arguments
82: ## Access type
83: ## A for address, only in memory
84: ## W for writing
85: ## R for reading
86: ## M for modifying
87: ## B for branch displacement
88: ## Data types
89: ## B byte
90: ## W word
91: ## L long
92: ## Q quad
93: ## F f_float
94: ## D d_float
95: ##
96: ## The order of instructions in this table is not critical;
97: ## the clients take care of their own table construction and ordering.
98: ## The instructions are grouped (more or less) into functional groups.
