ADT ast-experimental enum pthread-emulation qualifiedEnum
Last change on this file since 22226e4 was 33b7d49, checked in by Andrew Beach <ajbeach@…>, 4 years ago

Added another check to checkInvariants for code locations. I also went through and made sure you can put it every after every new AST pass not followed by a forceFillCodeLocations.
