Please insist in that it is a once in a lifetime opportunity for Cadence to have its XTensa architecture to reach the public!

Agreed. If they still don't want to, is there a way they can release some docs disclosing the specifics of the CALL0 abi?

But I really mean it: if they want the XTensa architecture to stand out and compete with ARM or MIPS core, this is the way to do it, now!

EDIT: actually, the XTensa GCC compiler in the VM is (somewhat) working, so if they can point us on one that was supposed to work, not necessarily the latest GCC.

Espressif is talking with Cadence, they just met last week about this. I am in direct contact with CEO of Espressif. (he called me ;) )
