Add instruction dump mode to insn_sanity tool for
checking decoder really decoded instructions.
This mode is enabled when passing double -v (-vv) to
insn_sanity. It is useful for who wants to check whether
the decoder can decode some instructions correctly.
e.g.
$ echo 0f 73 10 11 | ./insn_sanity -y -vv -i -
Instruction = {
.prefixes = {
.value = 0, bytes[] = {0, 0, 0, 0},
.got = 1, .nbytes = 0},
.rex_prefix = {
.value = 0, bytes[] = {0, 0, 0, 0},
.got = 1, .nbytes = 0},
.vex_prefix = {
.value = 0, bytes[] = {0, 0, 0, 0},
.got = 1, .nbytes = 0},
.opcode = {
.value = 29455, bytes[] = {f, 73, 0, 0},
.got = 1, .nbytes = 2},
.modrm = {
.value = 16, bytes[] = {10, 0, 0, 0},
.got = 1, .nbytes = 1},
.sib = {
.value = 0, bytes[] = {0, 0, 0, 0},
.got = 1, .nbytes = 0},
.displacement = {
.value = 0, bytes[] = {0, 0, 0, 0},
.got = 1, .nbytes = 0},
.immediate1 = {
.value = 17, bytes[] = {11, 0, 0, 0},
.got = 1, .nbytes = 1},
.immediate2 = {
.value = 0, bytes[] = {0, 0, 0, 0},
.got = 0, .nbytes = 0},
.attr = 44800, .opnd_bytes = 4, .addr_bytes = 8,
.length = 4, .x86_64 = 1, .kaddr = 0x7fff0f7d9430}
Success: decoded and checked 1 given instructions with 0 errors (seed:0x0)
