- Unfortunately it doesn't seem possible to order the
- table on much more than the major opcode, which makes
- it difficult to implement a binary search in the
- disassembler. The problem is that we have multiple
- ways to disassemble instructions, and we usually want
- to choose a more specific form (with more bits set in
- the opcode) than a more general form. eg. all of the
- following are equivalent:
- bne label # opcode = 0x40820000, mask = 0xff830003
- bf 2,label # opcode = 0x40800000, mask = 0xff800003
- bc 4,2,label # opcode = 0x40000000, mask = 0xfc000003
-
- There are also cases where the table needs to be out
- of order to disassemble the correct instruction for
- processor variants. */
