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
