How Do Assemblers Map x86 Instruction Mnemonics to Binary Machine Instructions?

Question

I\'m interested in writing an x86 assembler. I\'m wondering what is a good way to map x86 assembly mnemonic instructions (using an Intel-like syntax) into the corresponding bina

It's just a straight-up one-to-one mapping; the Intel documentation describes all of the instructions and their encodings. You'll need to build a giant lookup table or something equivalent to do the matching and code generation.
