annotate dmd/aggregate.h @ 1482:d9c5f5a43403
Run `semantic3` on imported modules, and emit new symbols with
`available_externally` linkage. This allows the inliner to inline functions from
other modules while telling the code generator to ignore those functions (treat
them as declarations)
Still generates a few extra `TypeInfo`s and strings...
Disabled when generating debug info because I don't really understand it, and it
doesn't like this.
