27 /* These are bit masks and shift counts to use to access the various
28 fields of an instruction. To retrieve the X field of an
29 instruction, use the expression
30 (i >> OP_SH_X) & OP_MASK_X
31 To set the same field (to j), use
32 i = (i &~ (OP_MASK_X << OP_SH_X)) | (j << OP_SH_X)
33
34 Make sure you use fields that are appropriate for the instruction,
35 of course.
36
37 The 'i' format uses OP, RS, RT and IMMEDIATE.
38
39 The 'j' format uses OP and TARGET.
40
41 The 'r' format uses OP, RS, RT, RD, SHAMT and FUNCT.
42
43 The 'b' format uses OP, RS, RT and DELTA.
44
45 The floating point 'i' format uses OP, RS, RT and IMMEDIATE.
46
47 The floating point 'r' format uses OP, FMT, FT, FS, FD and FUNCT.
48
49 A breakpoint instruction uses OP, CODE and SPEC (10 bits of the
50 breakpoint instruction are not defined; Kane says the breakpoint
51 code field in BREAK is 20 bits; yet MIPS assemblers and debuggers
52 only use ten bits). An optional two-operand form of break/sdbbp
53 allows the lower ten bits to be set too, and MIPS32 and later
54 architectures allow 20 bits to be set with a signal operand
55 (using CODE20).
56
57 The syscall instruction uses CODE20.
58
59 The general coprocessor instructions use COPZ. */
