Comment Actions Out of curiosity, what is your interest in Zbt? Do you work for a company that is implementing this extension in hardware?
Comment Actions My company has not implementing this extension,but may be in the future. I'm just doing a pre-research.
Comment Actions The Zbt extensions and the other un-ratified extension from the old Bitmanip spec have not seen any active discussion for at least the last 6-9 months. If that continues, it starts to raise questions about whether llvm should continue to support and extension that does not appear to be on a path to ratification. I've asked for a discussion on this topic at the next RISCV LLVM bi-weekly sync meeting tomorrow morning US time. calendar link here https://llvm.org/docs/GettingInvolved.html#online-sync-ups |
