Original Instruction table specification document:
|
||
|
||
MIPS Coprocessor Table Specification
|
||
====================================
|
||
|
||
This document describes the format of the MIPS coprocessor table. 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". These instructions are already recognized
|
||
by the assembler, and are listed here only for reference.
|
||
|
||
Class format instructions
|
||
-------------------------------------------------
|
||
Class1:
|
||
op base rt offset
|
||
LWCz rt,offset (base)
|
||
SWCz rt,offset (base)
|
||
Class2:
|
||
COPz sub rt rd 0
|
||
MTCz rt,rd
|
||
MFCz rt,rd
|
||
CTCz rt,rd
|
||
CFCz rt,rd
|
||
Class3:
|
||
COPz CO cofun
|
||
COPz cofun
|
||
Class4:
|
||
COPz BC br offset
|
||
BCzT offset
|
||
BCzF offset
|
||
Class5:
|
||
COPz sub rt rd 0
|
||
DMFCz rt,rd
|
||
DMTCz rt,rd
|
||
Class6:
|
||
op base rt offset
|
||
LDCz rt,offset (base)
|
||
SDCz rt,offset (base)
|
||
Class7:
|
||
COPz BC br offset
|
||
BCzTL offset
|
||
BCzFL offset
|
||
|
||
The coprocessor table defines coprocessor-specific registers that can
|
||
be used with all of the above classes of instructions, where
|
||
appropriate. 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! should really change lexical analyzer
|
||
to recognize 'dreg' etc. in context sensitive way.
|
||
Currently function names or mnemonics may be incorrectly parsed as keywords
|
||
|
||
FIXME! hex is ambiguous with any digit
