comparison gen/main.cpp @ 1482:d9c5f5a43403

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
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.
