The basic way that it works is as follows, where `C`is the name of the class being defined or the target of a call andthe function type is assumed to be `void()`.For virtual calls:- Attach type metadata to the addresses of function pointers in vtables (not the functions themselves) of type `void (B::*)()` for each `B` that is a recursive dynamic base class of `C`, including `C` itself. This type metadata has an annotation that the type is for virtual calls (to distinguish it from the non-virtual case).- At the call site, check that the computed address of the function pointer in the vtable has type `void (C::*)()`.For non-virtual calls:- Attach type metadata to each non-virtual member function whose address can be taken with a member function pointer. The type of a function in class `C` of type `void()` is each of the types `void (B::*)()` where `B` is a most-base class of `C`. A most-base class of `C` is defined as a recursive base class of `C`, including `C` itself, that does not have any bases.- At the call site, check that the function pointer has one of the types `void (B::*)()` where `B` is a most-base class of `C`.Differential Revision: https://reviews.llvm.org/D47567llvm-svn: 335569 List of files: /llvm-project-15.0.7/compiler-rt/test/cfi/mfcall.cpp Tue, 26 Jun 2018 02:15:47 +0000 Peter Collingbourne <peter@pcc.me.uk>
