Detailed Description

Provider for named objects defined in the debug info for Clang.

As Clang parses an expression, it may encounter names that are not defined inside the expression, including variables, functions, and types. Clang knows the name it is looking for, but nothing else. The ExternalSemaSource class provides Decls (VarDecl, FunDecl, TypeDecl) to Clang for these names, consulting the ClangExpressionDeclMap to do the actual lookups.
