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.
I'm getting the following build error on an old K7 box:
arch/x86/lib/inat.c: In function ‘inat_get_opcode_attribute’:
arch/x86/lib/inat.c:29: erreur: ‘inat_primary_table’ undeclared (first use in this function)
arch/x86/lib/inat.c:29: erreur: (Each undeclared identifier is reported only once
arch/x86/lib/inat.c:29: erreur: for each function it appears in.)
Thanks for reporting!
Hmm, it seems that inat-tables.c is not correctly generated.
Could you tell me which awk you used and send the inat-tables.c?
Thank you,
