Detailed Description

ASTImporter that intercepts and records the import process of the underlying ASTImporter.

This class updates the map from declarations to their original declarations and can record declarations that have been imported in a certain interval.

When intercepting a declaration import, the ASTImporterDelegate uses the CxxModuleHandler to replace any missing or malformed declarations with their counterpart from a C++ module.

m_decls_to_ignore

llvm::SmallPtrSet<clang::Decl *, 16> lldb_private::ClangASTImporter::ASTImporterDelegate::m_decls_to_ignore

private

Decls we should ignore when mapping decls back to their original ASTContext.

Used by the CxxModuleHandler to mark declarations that were created from the 'std' C++ module to prevent that the Importer tries to sync them with the broken equivalent in the debug info AST.
