Note that the Plan 9 compilers do not actually generate
machine code. They build an intermediate abstract object
code that the linkers then translate into machine code.

The syntax used by the assemblers is essentially a textual
representation of that intermediate code. If you want to
understand the design and it's idiosyncrasies, focus on the
latter.
