#282 I'm pretty good at gcc hacking, but I wouldn't want to undertake updating the Xtensa support in gcc all by myself. Is there an IRC channel for this?

#369 So, reporting gcc status:

- no support for call0 ABI in current gcc;
- nobody in Cadence is currently working on implementing it;
- whether that support could be implemented by Cadence is discussed, my estimation that the answer would be positive is low.

I have almost no knowledge of gcc internals, but I've a lot of experience with xtensa architecture. Please let me know if I can be of any help implementing call0 ABI.
