why doesn't assembly language have a parse tree?

There isn't any part of it that's tree-like.

ASTs are bloat

file ::= (label | instruction)+

label ::= id ':'

instruction ::= mnemonic(op (op)?)?

mnemonic::= id
op ::= id // todo add different op types

how do you accomidate affixes? cisc assembly isn't an isolating language like most formal languages, it's polysynthetic. operands can have (restricted) arithmetic expressions, and instructions can have suffixes and infixes. also you haven't accounted for pointer dereferencing, non-instruction directives, literals, segments, etc.

Those expressions are parsed by the assembler, encoded and then promptly discarded.

I'm pretty sure that anon wasn't intending his post to be comprehensive.
