Intel and AT&T assembly syntax highlighting in TextMate

Question

How do I get Intel and AT&T assembly syntax highlighting in TextMate?

Answer 1

I find this answer is helpful.

GAS-x86 (or x64) highlighting scheme

Open Package Control, type gasx to find the package.

Answer 2

Can this be of use?

x86 Assembly.tmbundle

I'm not familiar with assembly syntax, so I can't test it apart from trying the examples on the Wikipedia article (that, for what matters, seem to work).

Answer 3

I couldn't find any existing bundles for any kind of assembly language, so you would have to write your own. Chapter 12 of the TextMate manual covers the basics of creating a grammar for highlighting which should get you started, plus there are a fair number of bundles out there you can look at to get ideas.
