◆ GetMangledName()

llvm::StringRef clang::IncrementalParser::GetMangledName ( GlobalDecl GD ) const

Uses the CodeGenModule mangled name cache and avoids recomputing.

Returns: the mangled name of a GD.

◆ Parse()

llvm::Expected< PartialTranslationUnit & > clang::IncrementalParser::Parse ( llvm::StringRef Input )

virtual

Parses incremental input by creating an in-memory file.

Returns: a PartialTranslationUnit which holds information about the TranslationUnitDecl and llvm::Module corresponding to the input.

Reimplemented in clang::IncrementalCUDADeviceParser.
