Zachary Snow 8a554113c8 don't process global items when looking up identifiers in packages 2021-07-19 12:33:11 -04:00
Zachary Snow 2eee536f62 enum conversion to handles additional scope conflicts 
- substitute enum item values directly into usage sites rather than
  creating synthetic localparams
- substitution handles shadowing of expressions in enum item values
- disconnected scopes can reference conflicting enum items

Zachary Snow 2e06d45ca0 fix inadvertent duplicate declaration generation 
Disabling the package item injection routine used in the enum conversion
when there were no items to inject exposed cases where conversions would
generate duplicate declarations. The hierarchical constant and param
type conversions were trivially affected. The package conversion could
inject class items within a generate region and then re-inject them
outside of that generate region. The package conversions now uses an
upgraded generate region flattening utility to ensure injected class
items are seen. This also includes coverage for a conflict which
occurred even without the enum conversion change.

Zachary Snow 3f20055cd6 proper support for static class methods 2021-06-24 22:15:46 -06:00
Zachary Snow 3955c47e7a support parameterized class items depending on local generate scopes 
- previously the overrides for parameterized data types could only
  reference data declarations at the module scope
- their use within procedures is still allowed, but cannot currently
  refer to localparams declared within procedures
- add procedure scope location accessors to allow scoped traversals to
  mark where injected items will end up in advance
