insn_get_opcode

函数名称：sn_get_opcode - collect opcode(s)*@insn: &struct insn containing instruction* Populates @insn->opcode, updates @insn->next_byte to point past the* opcode byte(s), and set @insn->attr (except for groups).

函数原型：void insn_get_opcode(struct insn *insn)

返回类型：void

参数：

类型	参数	名称
struct insn *	insn

opcode等于* opcode.bytes[0]: opcode1 * opcode.bytes[1]: opcode2 * opcode.bytes[2]: opcode3

239

如果 !0 if we've run insn_get_xxx() for this field 则返回

241

如果非 !0 if we've run insn_get_xxx() for this field 则sn_get_prefixes - scan x86 instruction prefix bytes*@insn: &struct insn containing instruction* Populates the @insn->prefixes bitmap, and updates @insn->next_byte* to point to the (first) opcode. No effect if @insn->prefixes.got* is already set.

245

op等于get_next(insn_byte_t, insn)

246

bytes[0]等于op

247

nbytes等于1

250

如果insn_is_avx(insn)则

252

m等于insn_vex_m_bits(insn)

253

p等于insn_vex_p_bits(insn)

254

attr等于inat_get_avx_attribute(op, m, p)

255

如果inat_must_evex(attr)且非insn_is_evex(insn)或非inat_accept_vex(attr)且非inat_is_group(attr)则attr等于0

259

转到:end

262

attr等于Attribute search APIs

263

当inat_is_escape(attr)循环

265

op等于get_next(insn_byte_t, insn)

266

bytes[nbytes++]等于op

267

pfx_id等于Get the last prefix id from last prefix or VEX prefix

268

attr等于inat_get_escape_attribute(op, pfx_id, attr)

270

如果inat_must_vex(attr)则attr等于0

272

end :

273

!0 if we've run insn_get_xxx() for this field 等于1
