Raw Normal View History

Implement various flavors of type merging. Previous algotirhm assumed that types and ids are in a single unified stream. For inputs that come from object files, this is the case. But if the input is already a PDB, or is the result of a previous merge, then the types and ids will already have been split up, in which case we need an algorithm that can accept operate on independent streams of types and ids that refer across stream boundaries to each other.
