v.g.vassilev added a comment. I am not sure if this is the right time but maybe testing and comparing the behavior of this patch against something such as the ODRHash will help you, me (and probably others) to understand the current patch better.
In https://reviews.llvm.org/D41416, I started working on lazy deserialization of template specializations. When you produce a PCM or PCH and a template instantiation is required it'd currently deserialize eagerly all possible template specializations (and standard libraries have a lot of them). I am computing the hashes of the template arguments and comparing against the usual Profile-ed hashes. In the assert, essentially I am comparing the behavior of the ODRHash and the Stmt::Profile logic for some cases. Perhaps you can plugin your algorithm to it, create a pch and start comparing your logic with the when it comes to template arguments hashing and alike. Of course this is not something that will give you perfect coverage and so on but it can stress test the implementation and compare it to the 2 major existing ones in clang. ================ Comment at: include/clang/AST/CHashVisitor.h:10 +// +// This file defines the APValue class. +// ---------------- I suspect this is a copy-paste from the APValue class.
