How to add project asm files with functions

Postby Deouss » Fri Dec 13, 2019 3:15 pm

Let's say I want to optimize certain subprocedures in my program and want to use assembly language.
What is the best way of doing that. Is it better to create them in separate .s files or mix in C/C++ ?
Also how do I do that and what special markup or setup do I need

Thanks

It depends on your purpose, that's why the options are both supported. And wrt 'special markup': you obviously need to use Xtensa assembly, but that's it from what I know.

I definitely need to use Xtensa assembly. Are there any guides or examples how to program in LX6/7 assembler?
Thanks

Sorry, there are not, and we're not allowed to release any ISA documents (it's under a NDA from Cadence)... however, if you google, something may turn up.
