https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102989#c13 has links to all the issues I filed requesting that ABIs be defined for _BitInt. At some point all GCC architecture maintainers should probably be asked to try to agree _BitInt ABIs with any psABI maintainers that may exist, or, failing a maintained psABI, with any other implementations for the architecture, or, failing other maintained implementations that support _BitInt or might do so in future, to write down a definition of the ABI being used by GCC for _BitInt on that architecture along with enabling the support in GCC. -- Joseph S.
