30 | /* These are bit masks and shift counts to use to access the various |
31 | fields of an instruction. To retrieve the X field of an | |
32 | instruction, use the expression | |
33 | (i >> OP_SH_X) & OP_MASK_X | |
34 | To set the same field (to j), use | |
35 | i = (i &~ (OP_MASK_X << OP_SH_X)) | (j << OP_SH_X) | |
36 | ||
37 | Make sure you use fields that are appropriate for the instruction, | |
8eaec934 | 38 | of course. |
252b5132 | 39 | |
8eaec934 | 40 | The 'i' format uses OP, RS, RT and IMMEDIATE. |
252b5132 RH |
41 | |
42 | The 'j' format uses OP and TARGET. | |
43 | ||
44 | The 'r' format uses OP, RS, RT, RD, SHAMT and FUNCT. | |
45 | ||
46 | The 'b' format uses OP, RS, RT and DELTA. | |
47 | ||
48 | The floating point 'i' format uses OP, RS, RT and IMMEDIATE. | |
49 | ||
50 | The floating point 'r' format uses OP, FMT, FT, FS, FD and FUNCT. | |
51 | ||
52 | A breakpoint instruction uses OP, CODE and SPEC (10 bits of the | |
53 | breakpoint instruction are not defined; Kane says the breakpoint | |
54 | code field in BREAK is 20 bits; yet MIPS assemblers and debuggers | |
55 | only use ten bits). An optional two-operand form of break/sdbbp | |
4372b673 NC |
56 | allows the lower ten bits to be set too, and MIPS32 and later |
57 | architectures allow 20 bits to be set with a signal operand | |
58 | (using CODE20). | |
252b5132 | 59 | |
4372b673 | 60 | The syscall instruction uses CODE20. |

62 | The general coprocessor instructions use COPZ. */ | |
