69/* These are bit masks and shift counts to use to access the various
70 fields of an instruction. To retrieve the X field of an
71 instruction, use the expression
72 (i >> OP_SH_X) & OP_MASK_X
73 To set the same field (to j), use
74 i = (i &~ (OP_MASK_X << OP_SH_X)) | (j << OP_SH_X)
75
76 Make sure you use fields that are appropriate for the instruction,
77 of course.
78
79 The 'i' format uses OP, RS, RT and IMMEDIATE.
80
81 The 'j' format uses OP and TARGET.
82
83 The 'r' format uses OP, RS, RT, RD, SHAMT and FUNCT.
84
85 The 'b' format uses OP, RS, RT and DELTA.
86
87 The floating point 'i' format uses OP, RS, RT and IMMEDIATE.
88
89 The floating point 'r' format uses OP, FMT, FT, FS, FD and FUNCT.
90
91 A breakpoint instruction uses OP, CODE and SPEC (10 bits of the
92 breakpoint instruction are not defined; Kane says the breakpoint
93 code field in BREAK is 20 bits; yet MIPS assemblers and debuggers
94 only use ten bits). An optional two-operand form of break/sdbbp
95 allows the lower ten bits to be set too, and MIPS32 and later
96 architectures allow 20 bits to be set with a signal operand
97 (using CODE20).
98
99 The syscall instruction uses CODE20.
100
101 The general coprocessor instructions use COPZ. */
