The -table specifies a list of valid functions, data registers and control -registers that can be used in coprocessor instructions. This list, -together with the coprocessor instruction classes listed below, -specifies the complete list of coprocessor instructions that will -be recognized and assembled by the GNU assembler. In effect, -this makes the GNU assembler table-driven, where the table is -specified by the programmer. - -The table is an ordinary text file that the GNU assembler reads when -it starts. Using the information in the table, the assembler -generates an internal list of valid coprocessor registers and -functions. The assembler uses this internal list in addition to the -standard MIPS registers and instructions which are built-in to the -assembler during code generation. - -To specify the coprocessor table when invoking the GNU assembler, use -the command line option "--itbl file", where file is the -complete name of the table, including path and extension. - -Examples: - - gas -t cop.tbl test.s -o test.o - gas -t /usr/local/lib/cop.tbl test.s -o test.o - gas --itbl d:\gnu\data\cop.tbl test.s -o test.o - -Only one table may be supplied during a single invocation of -the assembler. - - -Instruction classes -=================== - -Below is a list of the valid coprocessor instruction classes for -any given coprocessor "z".

It also defines additional coprocessor-specific -functions for Class3 (COPz cofun) instructions, Thus, the table allows -the programmer to use convenient mnemonics and operands for these -functions, instead of the COPz mmenmonic and cofun operand. - -The names of the MIPS general registers and their aliases are defined -by the assembler and will be recognized as valid register names by the -assembler when used (where allowed) in coprocessor instructions. -However, the names and values of all coprocessor data and control -register mnemonics must be specified in the coprocessor table. - - -Table Grammar -============= - -Here is the grammar for the coprocessor table: - - table -> entry* - - entry -> [z entrydef] [comment] '\n' - - entrydef -> type name val - entrydef -> 'insn' name val funcdef ; type of entry (instruction) - - z -> 'p'['0'..'3'] ; processor number - type -> ['dreg' | 'creg' | 'greg' ] ; type of entry (register) - ; 'dreg', 'creg' or 'greg' specifies a data, control, or general - ; register mnemonic, respectively - name -> [ltr|dec]* ; mnemonic of register/function - val -> [dec|hex] ; register/function number (integer constant) - - funcdef -> frange flags fields - ; bitfield range for opcode - ; list of fields' formats - fields -> field* - field -> [','] ftype frange flags - flags -> ['*' flagexpr] - flagexpr -> '[' flagexpr ']' - flagexpr -> val '|' flagexpr - ftype -> [ type | 'immed' | 'addr' ] - ; 'immed' specifies an immediate value; see grammar for "val" above - ; 'addr' specifies a C identifier; name of symbol to be resolved at - ; link time - frange -> ':' val '-' val ; starting to ending bit positions, where - ; where 0 is least significant bit - frange -> (null) ; default range of 31-0 will be assumed - - comment -> [';'|'#'] [char]* - char -> any printable character - ltr -> ['a'..'z'|'A'..'Z'] - dec -> ['0'..'9']* ; value in decimal - hex -> '0x'['0'..'9' | 'a'..'f' | 'A'..'F']* ; value in hexadecimal - - -Examples -======== - -Example 1: - -The table: - - p1 dreg d1 1 ; data register "d1" for COP1 has value 1 - p1 creg c3 3 ; ctrl register "c3" for COP1 has value 3 - p3 func fill 0x1f:24-20 ; function "fill" for COP3 has value 31 and - ; no fields - -will allow the assembler to accept the following coprocessor instructions: - - LWC1 d1,0x100 ($2) - fill - -Here, the general purpose register "$2", and instruction "LWC1", are standard -mnemonics built-in to the MIPS assembler. - - -Example 2: - -The table: - - p3 dreg d3 3 ; data register "d3" for COP3 has value 3 - p3 creg c2 22 ; control register "c2" for COP3 has value 22 - p3 func fee 0x1f:24-20 dreg:17-13 creg:12-8 immed:7-0 - ; function "fee" for COP3 has value 31, and 3 fields - ; consisting of a data register, a control register, - ; and an immediate value. - -will allow the assembler to accept the following coprocessor instruction: - - fee d3,c2,0x1 - -and will emit the object code: - - 31-26 25 24-20 19-18 17-13 12-8 7-0 - COPz CO fun dreg creg immed - 010011 1 11111 00 00011 10110 00000001 - - 0x4ff07601 - - -Example 3: - -The table: - - p3 dreg d3 3 ; data register "d3" for COP3 has value 3 - p3 creg c2 22 ; control register "c2" for COP3 has value 22 - p3 func fuu 0x01f00001 dreg:17-13 creg:12-8 - -will allow the assembler to accept the following coprocessor -instruction: - - fuu d3,c2 - -and will emit the object code: - - 31-26 25 24-20 19-18 17-13 12-8 7-0 - COPz CO fun dreg creg - 010011 1 11111 00 00011 10110 00000001 - - 0x4ff07601 - -In this way, the programmer can force arbitrary bits of an instruction -to have predefined values. - -======================================================================= -Additional notes: - -Encoding of ranges: -To handle more than one bit position range within an instruction, -use 0s to mask out the ranges which don't apply. -May decide to modify the syntax to allow commas separate multiple -ranges within an instruction (range','range). - -Changes in grammar: - The number of parms argument to the function entry -was deleted from the original format such that we now count the fields. - ----- -FIXME!
