Ben Lubar cc2c732dd5
insert a new second rule for tagged union discovery
1. if the field name ends in "data" and there is a field with the same
   prefix ending in "type", the field ending in "type" is the tag.
2. if the field name ends in "_target" and the previous field has the
   same prefix and no suffix, the previous field is the tag.
3. if the field is not the last field in the structure, the next field
   is the tag.

Convert untagged unions to tagged. Fix some edge cases in check-structures-sanity union checking. 2020-02-29 15:08:39 -06:00

check-structures-sanity improvements for unidentified fields and unions
- not being able to determine the tag for a union is now an error.
- pointer-sized unknown allocations will now be checked recursively as
  if they were void pointers. this will help with identifying string
  pointers on linux.
- unknown tagged union fields will be checked as void pointers if the
  first identified field of the union is a pointer.
- tagged unions can now be of non-pointer types.
- tagged unions can now have complex tag enums.
