It's fully documented in the unified 32-bit ABI document (under

Hi all,
FYI The next RISC-V GNU Toolchain Biweekly Sync is cancelled because
the developers from mainland China are still on their National Holiday.
There were not too much new topics in the past weeks, except a few
psABI issues, which could be postponed to the next meeting.
