ADT ast-experimental enum forall-pointer-decay pthread-emulation qualifiedEnum
Last change on this file since a73c16e was 68fe946e, checked in by Andrew Beach <ajbeach@…>, 4 years ago

Updated DeclStats for the new ast. Also fixed a bug in the old implementation (apparently it hasn't been used since gcc-builtins were added).
