10 // CodeGenABITypes is a simple interface for getting LLVM types for
11 // the parameters and the return value of a function given the Clang
14 // The class is implemented as a public wrapper around the private
15 // CodeGenTypes class in lib/CodeGen.
17 // It allows other clients, like LLDB, to determine the LLVM types that are
18 // actually used in function calls, which makes it possible to then determine
19 // the actual ABI locations (e.g. registers, stack locations, etc.) that
20 // these parameters are stored in.
