package p

import "encoding/binary"

func f(b []byte, x *[8]byte) {
	_ = b[8]
	t := binary.BigEndian.Uint64(x[:])
	binary.BigEndian.PutUint64(b, t)
}

This should compile down to two MOVQs on amd64, one to load from x and one to write to b.

Instead, it contains two successive BSWAP instructions. We should eliminate those. As a bonus, we should eliminate any BSWAPS separated only by bitwise operations. For example:

package p

import "encoding/binary"

func f(b []byte, x *[8]byte) {
	_ = b[8]
	t := binary.BigEndian.Uint64(x[:])
	t = ^t
	binary.BigEndian.PutUint64(b, t)
}

(In addition to unary ^, there's binary &, |, and ^. Maybe some others?)

One advantage to this kind of optimization is that it reduces the important of whether the endianness selected in the code matches the endianness of the architecture the code is being executed on.

This allows IP manipulation operations to operate on IPs as two registers, which empirically
leads to significant speedups, in particular on OOO superscalars where the two halves can
be processed in parallel.

You might expect that we could keep the representation as [16]byte, and do a cycle of
BigEndian.Uint64+tweak+BigEndian.PutUint64, and that would compile down to efficient
code. Unfortunately, due to a variety of missing optimizations in the Go compiler,
that is not the case and that code turns into byte-wise operations. On the other hand,
converting to a uint64 pair at construction results in efficient construction (a pair of
MOVQ+BSWAPQ) and efficient twiddling operations (single-cycle arithmetic on 64-bit
pairs). See also:

This allows IP manipulation operations to operate on IPs as two registers, which empirically
leads to significant speedups, in particular on OOO superscalars where the two halves can
be processed in parallel.

You might expect that we could keep the representation as [16]byte, and do a cycle of
BigEndian.Uint64+tweak+BigEndian.PutUint64, and that would compile down to efficient
code. Unfortunately, due to a variety of missing optimizations in the Go compiler,
that is not the case and that code turns into byte-wise operations. On the other hand,
converting to a uint64 pair at construction results in efficient construction (a pair of
MOVQ+BSWAPQ) and efficient twiddling operations (single-cycle arithmetic on 64-bit
pairs). See also:

@josharian, I'd like to work on this one, too, as I guess it's quite similar to #41663

By the way, should this one be added to go1.17 too?
