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...
