Classes
class	clang::LangOptionsBase
	Bitfields of LangOptions, split out from LangOptions in order to ensure that this large collection of bitfields is a trivial class type. More...

class	clang::LangOptions
	Keeps track of the various options that can be enabled, which controls the dialect of C or C++ that is accepted. More...

class	clang::FPOptions

class	clang::FPOptionsOverride
	Represents difference between two FPOptions values. More...

Namespaces
namespace	clang
	The JSON file list parser is used to communicate input to InstallAPI.

Enumerations
enum class	clang::MSVtorDispMode { clang::Never, clang::ForVBaseOverride, clang::ForVFTable }
	In the Microsoft ABI, this controls the placement of virtual displacement members used to implement virtual inheritance. More...

	Shader programs run in specific pipeline stages. More...

enum class	clang::PointerAuthenticationMode : unsigned { clang::None, clang::Strip, clang::SignAndStrip, clang::SignAndAuth }

enum	clang::TranslationUnitKind { clang::TU_Complete, clang::TU_Prefix, clang::TU_ClangModule, clang::TU_Incremental }
	Describes the kind of translation unit being processed. More...
