Most of the others rearrange the order of decoding of relevant parts of the insn, with the goal of shrinking overall table sizes. This goes along the lines of earlier changes towards the same goal. If I had recognized earlier the issue the last patch fixes, I would have put it near the beginning of this series. Re- basing ahead, however, turned out rather undesirable. 1: correct decoding of nop/reserved space (0f18 ... 0x1f) 2: re-arrange order of decode for various legacy opcodes 3: re-arrange order of decode for various VEX opcodes 4: re-arrange order of decode for various mask reg opcodes 5: re-arrange order of decode for various EVEX opcodes 6: reuse VEX entries for EVEX vperm{q,pd} 7: reuse further VEX entries for EVEX 8: rearrange enumerator and table entry order 9: Intel: correct AVX512 S/G disassembly Jan
