--- Comment #7 from sandra at gcc dot gnu.org --- I've swapped out just about all the details on this work after more than a year, but.... we shouldn't be trying to create a CFI descriptor with BT_ASSUMED at all, should we? If the compiler is generating a CFI descriptor for an assumed-type argument it's supposed to use the actual type of the argument passed, not BT_ASSUMED, right? If gcc 11 had a bug that caused it to do that incorrectly, is it necessary to retain ABI compatibility by continuing to reproduce the bug in newer versions of libgfortran? Maybe we should just remove the functions that are allegedly there for compatibility so that users will get a link error instead?
