The NASM 2 series supports x86-64, and is the production version of NASM
since 2007.
\S{cl-2.12.03} Version 2.12.03
\b Add new warnings for certain dangerous constructs which never ought
to have been allowed. In particular, the \c{RESB} family of
instructions should have been taking a critical expression all
along.
\b Fix the EVEX (AVX-512) versions of the \c{VPBROADCAST}, \c{VPEXTR},
and \c{VPINSR} instructions.
\b Support contracted forms of additional instructions. As a general
rule, if an instruction has a non-destructive source immediately
after a destination register that isn't used as an input, NASM
supports omitting that source register, using the destination
register as that value. This among other things makes it easier to
convert SSE code to the equivalent AVX code:
\c addps xmm1,xmm0 ; SSE instruction
\c vaddps ymm1,ymm1,ymm0 ; AVX official long form
\c vaddps ymm1,ymm0 ; AVX contracted form
\b Fix Codeview malformed compiler version record.
\b Add the \c{CLWB} and \c{PCOMMIT} instructions. Note that the
\c{PCOMMIT} instruction has been deprecated and will never be
included in a shipping product; it is included for completeness
only.

\b If the MASM \c{PTR} keyword is encountered, issue a warning. This is
much more likely to indicate a MASM-ism encountered in NASM than it
is a valid label. This warning can be suppressed with \c{-w-ptr},
the \c{[warning]} directive (see \k{opt-w}) or by the macro
