Hi Nicolas,

Thanks for your mail. From the four LLVM patches needed described in [1], the first one (L1) has landed upstream [2]. Regarding the other ones and your other questions, we are waiting for more information and we will keep you updated as soon as possible.

Kind regards, Hugues

Hi

My company SoloKeys produces open source FIDO2 security tokens (USB + NFC), and we're in the process of a) moving to a Cortex-M33 microcontroller, and b) an implementation in Rust.

This is mostly to say that we're very interested in the security extensions [1] landing in LLVM, so embedded Rust can eventually use them, I understand Hugues de Valon from Arm has done some exploratory work on this.

What is the status of this upstreaming process, are there any road blocks, and is there any ETA on public availability?

Regards, Nicolas Stalder SoloKeys
