27 * Throughout this file, the instruction format names based on:
28 * SA22-7832-09 z/Architecture Principles of Operation
29 *
30 * System/370, ESA/390, and earlier z/Architecture POP use slightly
31 * different names for the formats (the variant names are numeric). For the
32 * sake of simplicity, we use the most detailed definitions - z/Architecture.
33 *
34 * For ESA/390 we map the formats:
35 * E -> E
36 * I -> I
37 * RR -> RR
38 * RRE -> RRE
39 * RRF -> RRD & RRFa-e
40 * RX -> RXa-b
41 * RXE -> RXE
42 * RXF -> RXF
43 * RS -> RSa-b
44 * RSE -> RSYa-b
45 * RSL -> RSLa
46 * RSI -> RSI
47 * RI -> RIa-c
48 * RIL -> RILa-c
49 * SI -> SI
50 * S -> S
51 * SS -> SSa-b & SSd-e
52 * SSE -> SSE
53 *
54 * For System/370 we map the formats:
55 * RR -> RR
56 * RX -> RXa-b
57 * RS -> RSa-b
58 * SI -> SI
59 * S -> S
60 * SS -> SSa-c
61 *
62 * Disassembly begins in tbl_xx. The first byte of the instruction is used
63 * as the index. This yields either an instruction or a sub-table.
64 *
65 * If an instruction is encountered, its format field is used to format the
66 * instruction.
67 *
68 * There are two types of sub-tables: extended opcode tables (indicated with
69 * IF_TBL) or a multiple mnemonics tables (indicated with IF_MULTI).
70 *
71 * Extended opcode tables indicade which additional bits of the instruction
72 * should be inspected. These bits are used as an index into the sub table.
73 *
74 * Multiple mnemonic tables are used to print different mnemonics depending
75 * on the architecture. Over the years, certain instructions got a new
76 * preferred mnemonic. For example, 0xa70 is test-under-mask-high (tmh) on
77 * System/390. On z/Architecture systems, the instruction behaves
78 * identically (and the assembler hapilly accepts tmh), but the preferred
79 * mnemonic is tmlh (test-under-mask-low-high) because z/Architecture
80 * extended the general purpose registers from 32 bits to 64 bits. The
81 * current architecture flag (e.g., F_390) is used to index into the
82 * sub-table.
83 *
84 * Regardless of which sub-table is encountered, the selected entry in the
85 * sub-table is interpreted using the same rules as the contents of tbl_xx.
86 *
87 * Finally, we use the extended opcode sub-table mechanism to pretty print
88 * the branching instructions. All branches are conditional based on a
89 * 4-bit mask indicating which value of the condition code will result in a
90 * taken branch. In order to produce a more human friendly output, we use
91 * the 4-bit mask as an extended opcode to break up the branching
92 * instruction into 16 different ones. For example, instead of printing:
93 *
94 * bc 7,0x123(%r1,%r2)
95 *
96 * we print:
97 *
98 * bne 0x123(%r1,%r2)
99 *
100 * Note that we are using designated initializers via the INSTR/TABLE/MULTI
101 * macros and therefore the below tables can be sparse. We rely on unset
102 * entries having zero format fields (aka. IF_INVAL) per C99.
