Detailed Description

Singleton class used to register debug options.

The OptionRegistry is responsible for managing lifetimes of the options and provides interfaces for option registration and reading values from options. This object is a singleton, only one instance should ever exist so that all options are registered in the same place.

Member Function Documentation

◆ get()

template<typename ValT , typename Base , ValTBase::* Mem>

ValT llvm::OptionRegistry::get ( ) const

inline

Returns the value of the option.

Template Parameters

ValT	type of the option's data
Base	class used to key the option
Mem	member of `Base` used for keying the option

Reads option values based on the key generated by the template parameters. Keying for get() is the same as keying for registerOption.

◆ instance()

OptionRegistry & OptionRegistry::instance ( )

static

Returns a reference to the singleton instance.

◆ registerOption()

template<typename ValT , typename Base , ValTBase::* Mem>

static void llvm::OptionRegistry::registerOption	(	StringRef	ArgStr,
		StringRef	Desc,
		const ValT &	InitValue
	)

inlinestatic

Registers an option with the OptionRegistry singleton.

Template Parameters

ValT	type of the option's data
Base	class used to key the option
Mem	member of `Base` used for keying the option

Options are keyed off the template parameters to generate unique static characters. The template parameters are (1) the type of the data the option stores (ValT), the class that will read the option (Base), and the member that the class will store the data into (Mem).
