x86: Instruction decoder API Add x86 instruction decoder to arch-specific libraries. This decoder can decode x86 instructions used in kernel into prefix, opcode, modrm, sib, displacement and immediates. This can also show the length of instructions. This version introduces instruction attributes for decoding instructions. The instruction attribute tables are generated from the opcode map file (x86-opcode-map.txt) by the generator script(gen-insn-attr-x86.awk). Currently, the opcode maps are based on opcode maps in Intel(R) 64 and IA-32 Architectures Software Developers Manual Vol.2: Appendix.A, and consist of below two types of opcode tables. 1-byte/2-bytes/3-bytes opcodes, which has 256 elements, are written as below; Table: table-name Referrer: escaped-name opcode: mnemonic|GrpXXX [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...] (or) opcode: escape # escaped-name EndTable Group opcodes, which has 8 elements, are written as below; GrpTable: GrpXXX reg: mnemonic [operand1[,operand2...]] [(extra1)[,(extra2)...] [| 2nd-mnemonic ...] EndTable These opcode maps include a few SSE and FP opcodes (for setup), because those opcodes are used in the kernel.
