/* These are bit masks and shift counts to use to access the various
|
29 |
|
|
fields of an instruction. To retrieve the X field of an
|
30 |
|
|
instruction, use the expression
|
31 |
|
|
(i >> OP_SH_X) & OP_MASK_X
|
32 |
|
|
To set the same field (to j), use
|
33 |
|
|
i = (i &~ (OP_MASK_X << OP_SH_X)) | (j << OP_SH_X)
|
34 |
|
|
|
35 |
|
|
Make sure you use fields that are appropriate for the instruction,
|
36 |
|
|
of course.
|
37 |

38 |
|
|
The 'i' format uses OP, RS, RT and IMMEDIATE.
|
39 |
|
|
|
40 |
|
|
The 'j' format uses OP and TARGET.
|
41 |
|
|
|
42 |
|
|
The 'r' format uses OP, RS, RT, RD, SHAMT and FUNCT.
|
43 |
|
|
|
44 |
|
|
The 'b' format uses OP, RS, RT and DELTA.
|
45 |
|
|
|
46 |
|
|
The floating point 'i' format uses OP, RS, RT and IMMEDIATE.
|
47 |
|
|
|
48 |
|
|
The floating point 'r' format uses OP, FMT, FT, FS, FD and FUNCT.
|
49 |
|
|
|
50 |
|
|
A breakpoint instruction uses OP, CODE and SPEC (10 bits of the
|
51 |
|
|
breakpoint instruction are not defined; Kane says the breakpoint
|
52 |
|
|
code field in BREAK is 20 bits; yet MIPS assemblers and debuggers
|
53 |
|
|
only use ten bits). An optional two-operand form of break/sdbbp
|
54 |
|
|
allows the lower ten bits to be set too, and MIPS32 and later
|
55 |
|
|
architectures allow 20 bits to be set with a signal operand
|
56 |
|
|
(using CODE20).
|
57 |
|
|
|
58 |
|
|
The syscall instruction uses CODE20.
|
59 |
|
|
|
60 |
|
|
The general coprocessor instructions use COPZ. */
