note: A leading bold V indicates that the instruction can be VEX-encoded, in which case it may have additional operands.
note: A leading bold ! indicates that the 256-bit version was only introduced with AVX2 and that it can only be VEX-encoded.

notes descriptions
#1 The use of Rb=AH/CH/DH/BH results in SPL/BPL/SIL/DIL. Without a REX.40 prefix, in case of the SSE version.
#2 The zero match codes are TD, TD (alias), MO, and MZ. They are encoded as the zzzz field of the Ib, using 0...3h.
#3 The condition codes are EQ/LT/LE and NEQ/NLT/NLE. They are encoded as the Ib, using 00h...02h and 04h...06h.
#4 The condition codes are EQ/LT/LE/FALSE and NEQ/NLT/NLE/TRUE. They are encoded as the Ib, using 00h...07h.
