The
Intel Architecture Software Developer's Manual, Vol 2: Instruction Set Reference
Appendix A, Table A-2,
the opcode corresponding to 0x33 currently states:
Gb, Ev
It should state:
Gv, Ev
Also, Page 3-791, XOR-Logical Exclusive OR, the two entries for opcode 33 currently state:

Description
33 /r
XOR r16,r/m16
r8 XOR r/m8
33 /r
XOR r32,r/m32
r8 XOR r/m8
It should state
:
Opcode
Instruction
Description
33 /r
r16 XOR r/m16
r8 XOR r/m8
33 /r
r32 XOR r/m32
r8 XOR r/m8

Incorrect Information for SLDT
In the
Intel Architecture Software Developer's Manual, Vol 2: Instruction Set Reference,
the
opcode/Instruction/Description table for SLDT currently states “SLDT
r/m32
Store segment selector from
LDTR in low-order 16 bits of
r/m32
” but should instead list “SLDT
r32
Store segment selector from LDTR in
low-order 16 bits of
r32
.”
In the
Intel Architecture Software Developer's Manual, Vol 2: Instruction Set Reference,
the sentence in the
LGDT/LIDT instruction section currently states:
”See 'SFENCE -- Store Fence' in this chapter for information on storing the contents of the GDTR
and IDTR."
It should state:
"See 'SGDT/SIDT' in this chapter for information on storing the contents of the GDTR and IDTR."
