Table: 1-byte opcode Alias: none 00: ADD Eb,Gb 01: ADD Ev,Gv 02: ADD Gb,Eb 03: ADD Gv,Ev 04: ADD AL,Ib 05: ADD rAX,Iz 06: PUSH ES (i64) 07: POP ES (i64) 08: OR Eb,Gb 09: OR Ev,Gv 0a: OR Gb,Eb 0b: OR Gv,Ev 0c: OR AL,Ib 0d: OR rAX,Iz 0e: PUSH CS 0f: 2-byte escape ... and a parser script which parses them into, const insn_attr_t primary_table[INAT_TABLE_SIZE] = { [0x04] = INAT_IMM(IMM_SIZE_BYTE) [0x05] = INAT_IMM(IMM_SIZE_VWORD32) [0x0c] = INAT_IMM(IMM_SIZE_BYTE) [0x0d] = INAT_IMM(IMM_SIZE_VWORD32) [0x0f] = INAT_ESC(IMM_ESC_2BYTE) ... (note, instructions which has no attributes for decoder, are just ignored) By the way, I'm worried about legal things of Intel's instruction encoding expressions. Would you think there is any problem if we have those tables in the kernel tree? Thanks, -- Masami Hiramatsu Software Engineer Hitachi Computer Products (America) Inc.
