hi!
A naughty error in the documentation which has given
me a headache:

>B.4.241 PMULHW, PMULLW: Multiply Packed 16-bit
Integers, and Store
>PMULxW takes two packed unsigned 16-bit integer
inputs, and multiplies the values in the inputs, forming
doubleword results.

This should be "two packed _signed_ 16-bit integer
inputs"

thanks,

    True.

    But then... an assembler manual should provide a list
    of noteworthy instructions, mnemonics, encodings, etc.
    instead of trying to serve as a fully-fledged ISA re-
    ference. IMO the latter should be left to Intel/AMD.

    Appendix B has been removed from the NASM manual due to the lack of a volunteer willing to maintain it.
