Pawel Szostek	46684bb28e	Use dynamic allocation for VHDL global built-in types Instead of using automatic variables for global types, I allocate them dynamically. Thanks to it, all type objects can be treated in the same way, as all of them are pointers allocated with `new'. Now we will be able to remove all scopes in the same manner, no matter if it is a global or local scope, by deleting all carried pointers.	2011-07-24 09:45:25 -07:00
Stephen Williams	3ff7a8f7b0	Add support for constants and package types. Significant rework of scope management to unify the handling of types in the ieee library and types/constants/components in packages. This involved adjusting the parser rules to manage a stack of scopes and rewriting the IEEE library support to not use global maps for the loaded types.	2011-04-17 17:19:09 -07:00
Stephen Williams	303f057de1	Support collecting ALL component declarations from a used scope.	2011-04-13 19:55:18 -07:00
Stephen Williams	d4c5cfc584	Add packages and component declarations within those packages. This creates the Package class to represent packages, and the Scope class to represent scopes in general. The library functions are worked up to support scanning scopes for declarations that are imported by "use" clauses.	2011-04-13 18:30:00 -07:00
