101 The args field is a string describing the operands. The following
102 letters can appear in the args:
103 c - a 5-bit control register index
104 d - a 5-bit destination register index
105 s - a 5-bit left source register index
106 t - a 5-bit right source register index
107 D - a 3-bit encoded destination register
108 S - a 3-bit encoded left source register
109 T - a 3-bit encoded right source register
110 i - a 16-bit signed immediate
111 j - a 5-bit unsigned immediate
112 k - a (second) 5-bit unsigned immediate
113 l - a 8-bit custom instruction constant
114 m - a 26-bit unsigned immediate
115 o - a 16-bit signed pc-relative offset
116 u - a 16-bit unsigned immediate
117 I - a 12-bit signed immediate
118 M - a 6-bit unsigned immediate
119 N - a 6-bit unsigned immediate with 2-bit shift
120 O - a 10-bit signed pc-relative offset with 1-bit shift
121 P - a 7-bit signed pc-relative offset with 1-bit shift
122 U - a 7-bit unsigned immediate with 2-bit shift
123 V - a 5-bit unsigned immediate with 2-bit shift
124 W - a 4-bit unsigned immediate with 2-bit shift
125 X - a 4-bit unsigned immediate with 1-bit shift
126 Y - a 4-bit unsigned immediate
127 e - an immediate coded as an enumeration for addi.n/subi.n
128 f - an immediate coded as an enumeration for slli.n/srli.n
129 g - an immediate coded as an enumeration for andi.n
130 h - an immediate coded as an enumeration for movi.n
131 R - a reglist for ldwm/stwm or push.n/pop.n
132 B - a base register specifier and option list for ldwm/stwm
133 Literal ',', '(', and ')' characters may also appear in the args as
134 delimiters.
135
136 Note that the args describe the semantics and assembly-language syntax
137 of the operands, not their encoding into the instruction word.
138
139 The pinfo field is INSN_MACRO for a macro. Otherwise, it is a collection
140 of bits describing the instruction, notably any relevant hazard
141 information.
142
143 When assembling, the match field contains the opcode template, which
144 is modified by the arguments to produce the actual opcode
145 that is emitted. If pinfo is INSN_MACRO, then this is 0.
146
147 If pinfo is INSN_MACRO, the mask field stores the macro identifier.
148 Otherwise this is a bit mask for the relevant portions of the opcode
149 when disassembling. If the actual opcode anded with the match field
150 equals the opcode field, then we have found the correct instruction. */

421 MATCH_R1_OPX0(NAME) and MASK_R1_OPX0 are used for R-type instructions
422 with 3 register operands and constant 0 in the immediate field.

424 constant values and MASK_R1_OPX(A, B, C, N) where the arguments are booleans
425 that are true if the field should be included in the mask.
