<p>
The assemblers are designed to support the compiler so not all hardware instructions
are defined for all architectures: if the compiler doesn't generate it, it might not be there.
If you need to use a missing instruction, there are two ways to proceed.
One is to update the assembler to support that instruction, which is straightforward

    > cd doc
    > rm -r next/*
    > cp -r initial/* next

Then edit `next/1-intro.md` to refer to the next version.

To prepare the release notes for a release, run `golang.org/x/build/cmd/relnote generate`.
