Hi Dan, It's been a couple months, and I didn't see any other feedback on this proposal. I was curious what the status of this work is. Are you able to attend GNU Cauldron[1] this year? I'd love to see this get some traction in GCC. Thanks! -Kees [1] https://gcc.gnu.org/wiki/cauldron2023 -- Kees Cook
