Yacc grammar for instruction table entries.

=======================================================================
105
Original Instruction table specification document:
106
 
107
            MIPS Coprocessor Table Specification
108
            ====================================
109
 
110
This document describes the format of the MIPS coprocessor table.  The
111
table specifies a list of valid functions, data registers and control
112
registers that can be used in coprocessor instructions.  This list,
113
together with the coprocessor instruction classes listed below,
114
specifies the complete list of coprocessor instructions that will
115
be recognized and assembled by the GNU assembler.  In effect,
116
this makes the GNU assembler table-driven, where the table is
117
specified by the programmer.
118
 
119
The table is an ordinary text file that the GNU assembler reads when
120
it starts.  Using the information in the table, the assembler
121
generates an internal list of valid coprocessor registers and
122
functions.  The assembler uses this internal list in addition to the
123
standard MIPS registers and instructions which are built-in to the
124
assembler during code generation.
125
 
126
To specify the coprocessor table when invoking the GNU assembler, use
127
the command line option "--itbl file", where file is the
128
complete name of the table, including path and extension.
129
 
130
Examples:
131
 
132
            gas -t cop.tbl test.s -o test.o
133
            gas -t /usr/local/lib/cop.tbl test.s -o test.o
134
            gas --itbl d:\gnu\data\cop.tbl test.s -o test.o
135
 
136
Only one table may be supplied during a single invocation of
137
the assembler.
138
 
139
 
140
Instruction classes
141
===================
142
 
143
Below is a list of the valid coprocessor instruction classes for
144
any given coprocessor "z".  These instructions are already recognized
145
by the assembler, and are listed here only for reference.
146
 
147

148
-------------------------------------------------

151

179
The coprocessor table defines coprocessor-specific registers that can
180
be used with all of the above classes of instructions, where
181
appropriate.  It also defines additional coprocessor-specific
182
functions for Class3 (COPz cofun) instructions, Thus, the table allows
183
the programmer to use convenient mnemonics and operands for these
184
functions, instead of the COPz mmenmonic and cofun operand.
185
 
186
The names of the MIPS general registers and their aliases are defined
187
by the assembler and will be recognized as valid register names by the
188
assembler when used (where allowed) in coprocessor instructions.
189
However, the names and values of all coprocessor data and control
190
register mnemonics must be specified in the coprocessor table.
191
 
192
 
193
Table Grammar
194
=============
195
 
196
Here is the grammar for the coprocessor table:
197
 
198
            table -> entry*
199
 
200
            entry -> [z entrydef] [comment] '\n'
201
 
202
            entrydef -> type name val
203
            entrydef -> 'insn' name val funcdef ; type of entry (instruction)
204
 
205
            z -> 'p'['0'..'3']               ; processor number
206
            type -> ['dreg' | 'creg' | 'greg' ]      ; type of entry (register)
207
        ; 'dreg', 'creg' or 'greg' specifies a data, control, or general
208
        ;           register mnemonic, respectively
209
            name -> [ltr|dec]*               ; mnemonic of register/function
210
            val -> [dec|hex]                 ; register/function number (integer constant)
211
 
212
            funcdef -> frange flags fields
213
                                ; bitfield range for opcode
214
                                ; list of fields' formats
215
            fields -> field*
216
            field -> [','] ftype frange flags
217
            flags -> ['*' flagexpr]
218
            flagexpr -> '[' flagexpr ']'
219
            flagexpr -> val '|' flagexpr
220
            ftype -> [ type | 'immed' | 'addr' ]
221
        ; 'immed' specifies an immediate value; see grammar for "val" above
222
                ; 'addr' specifies a C identifier; name of symbol to be resolved at
223
        ;           link time
224
            frange -> ':' val '-' val   ; starting to ending bit positions, where
225
                                ; where 0 is least significant bit
226
            frange -> (null)            ; default range of 31-0 will be assumed
227
 
228
            comment -> [';'|'#'] [char]*
229
            char -> any printable character
230
            ltr -> ['a'..'z'|'A'..'Z']
231
            dec -> ['0'..'9']*                                       ; value in decimal
232
            hex -> '0x'['0'..'9' | 'a'..'f' | 'A'..'F']*        ; value in hexadecimal
233
 
234
 
235
Examples
236
========
237
 
238
Example 1:
239
 
240
The table:
241
 
242
            p1 dreg d1 1             ; data register "d1" for COP1 has value 1
243
            p1 creg c3 3             ; ctrl register "c3" for COP1 has value 3
244
            p3 func fill 0x1f:24-20           ; function "fill" for COP3 has value 31 and
245
                        ; no fields
246
 
247
will allow the assembler to accept the following coprocessor instructions:
248
 
249
            LWC1 d1,0x100 ($2)
250
            fill
251
 
252
Here, the general purpose register "$2", and instruction "LWC1", are standard
253
mnemonics built-in to the MIPS assembler.
254
 
255
 
256
Example 2:
257
 
258
The table:
259
 
260
            p3 dreg d3 3             ; data register "d3" for COP3 has value 3
261
            p3 creg c2 22            ; control register "c2" for COP3 has value 22
262
            p3 func fee 0x1f:24-20 dreg:17-13 creg:12-8 immed:7-0
263
                ; function "fee" for COP3 has value 31, and 3 fields
264
                ; consisting of a data register, a control register,
265
                ; and an immediate value.
266
 
267
will allow the assembler to accept the following coprocessor instruction:
268
 
269
            fee d3,c2,0x1
270
 
271
and will emit the object code:
272
 
273
            31-26  25 24-20 19-18  17-13 12-8  7-0
274
            COPz   CO fun                     dreg  creg  immed
275
            010011 1  11111 00       00011 10110 00000001
276
 
277
            0x4ff07601
278
 
279
 
280
Example 3:
281
 
282
The table:
283
 
284
            p3 dreg d3 3             ; data register "d3" for COP3 has value 3
285
            p3 creg c2 22            ; control register "c2" for COP3 has value 22
286
            p3 func fuu 0x01f00001 dreg:17-13 creg:12-8
287
 
288
will allow the assembler to accept the following coprocessor
289
instruction:
290
 
291
            fuu d3,c2
292
 
293
and will emit the object code:
294
 
295
            31-26  25 24-20 19-18  17-13 12-8  7-0
296
            COPz   CO fun                     dreg  creg
297
            010011 1  11111 00       00011 10110 00000001
298
 
299
            0x4ff07601
300
 
301
In this way, the programmer can force arbitrary bits of an instruction
302
to have predefined values.
303
 
304
=======================================================================
305
Additional notes:
306
 
307
Encoding of ranges:
308
To handle more than one bit position range within an instruction,
309
use 0s to mask out the ranges which don't apply.
310
May decide to modify the syntax to allow commas separate multiple
311
ranges within an instruction (range','range).
312
 
313
Changes in grammar:
314
        The number of parms argument to the function entry
315
was deleted from the original format such that we now count the fields.
316
 
317
----
318
FIXME! should really change lexical analyzer
319
to recognize 'dreg' etc. in context sensitive way.
320
Currently function names or mnemonics may be incorrectly parsed as keywords
321
 
322
FIXME! hex is ambiguous with any digit
