Q: IRTools as assembler input?

Hi,
(maybe this is completely out of reach, I did not find an answer on Discourse)
- what would it take to add type information?
- what else is missing to use IRTools or @code_xxx for assembler input?
Even with restrictions, would be helpful:
GNU Assembler Examples (lmu.edu)
Creating Assembly Language DLL Modules for Windows - CodeProject
Writing DLL in Assembly Language for External Calling in Maple - Application Center (maplesoft.com)
Thx!
