|
---|
43 | * -----------------------
|
---|
44 | *
|
---|
45 | * All sections begin with 80 X's in a row followed by an end-of-line
|
---|
46 | * sequence.
|
---|
47 | * After this, m68kmake will expect to find one of the following section
|
---|
48 | * identifiers:
|
---|
49 | * M68KMAKE_PROTOTYPE_HEADER - header for opcode handler prototypes
|
---|
50 | * M68KMAKE_PROTOTYPE_FOOTER - footer for opcode handler prototypes
|
---|
51 | * M68KMAKE_TABLE_HEADER - header for opcode handler jumptable
|
---|
52 | * M68KMAKE_TABLE_FOOTER - footer for opcode handler jumptable
|
---|
53 | * M68KMAKE_TABLE_BODY - the table itself
|
---|
54 | * M68KMAKE_OPCODE_HANDLER_HEADER - header for opcode handler implementation
|
---|
55 | * M68KMAKE_OPCODE_HANDLER_FOOTER - footer for opcode handler implementation
|
---|
56 | * M68KMAKE_OPCODE_HANDLER_BODY - body section for opcode handler implementation
|
---|
57 | *
|
---|
58 | * NOTE: M68KMAKE_OPCODE_HANDLER_BODY must be last in the file and
|
---|
59 | * M68KMAKE_TABLE_BODY must be second last in the file.
|
---|
60 | *
|
---|
61 | * The M68KMAKE_OPHANDLER_BODY section contains the opcode handler
|
---|
62 | * primitives themselves. Each opcode handler begins with:
|
---|
63 | * M68KMAKE_OP(A, B, C, D)
|
---|
64 | *
|
---|
65 | * where A is the opcode handler name, B is the size of the operation,
|
---|
66 | * C denotes any special processing mode, and D denotes a specific
|
---|
67 | * addressing mode.
|
---|
68 | * For C and D where nothing is specified, use "."
|
---|
69 | *
|
---|
70 | * Example:
|
---|
71 | * M68KMAKE_OP(abcd, 8, rr, .) abcd, size 8, register to register, default EA
|
---|
72 | * M68KMAKE_OP(abcd, 8, mm, ax7) abcd, size 8, memory to memory, register X is A7
|
---|
73 | * M68KMAKE_OP(tst, 16, ., pcix) tst, size 16, PCIX addressing
|
---|
74 | *
|
---|
75 | * All opcode handler primitives end with a closing curly brace "}" at column 1
|
---|
76 | *
|
---|
77 | * NOTE: Do not place a M68KMAKE_OP() directive inside the opcode handler,
|
---|
78 | * and do not put a closing curly brace at column 1 unless it is
|
---|
79 | * marking the end of the handler!
|
---|
80 | *
|
---|
81 | * Inside the handler, m68kmake will recognize M68KMAKE_GET_OPER_xx_xx,
|
---|
82 | * M68KMAKE_GET_EA_xx_xx, and M68KMAKE_CC directives, and create multiple
|
---|
83 | * opcode handlers to handle variations in the opcode handler.
|
---|
84 | * Note: M68KMAKE_CC will only be interpreted in condition code opcodes.
|
---|
85 | * As well, M68KMAKE_GET_EA_xx_xx and M68KMAKE_GET_OPER_xx_xx will only
|
---|
86 | * be interpreted on instructions where the corresponding table entry
|
---|
87 | * specifies multiple effective addressing modes.
|
---|
88 | * Example:
|
---|
89 | * clr 32 . . 0100001010...... A+-DXWL... U U U 12 6 4
|
---|
90 | *
|
---|
91 | * This table entry says that the clr.l opcde has 7 variations (A+-DXWL).
|
---|
92 | * It is run in user or supervisor mode for all CPUs, and uses 12 cycles for
|
---|
93 | * 68000, 6 cycles for 68010, and 4 cycles for 68020.
