Detailed Description

This corresponds to a single GCC Multilib, or a segment of one controlled by a command line flag.

See also MultilibBuilder for building a multilib by mutating it incrementally.

using clang::driver::Multilib::flags_list = std::vector<std::string>

Constructor & Destructor Documentation

Multilib()

Multilib::Multilib	(	StringRef	GCCSuffix = {},
		StringRef	OSSuffix = {},
		StringRef	IncludeSuffix = {},
		const flags_list &	Flags = flags_list(),
		StringRef	ExclusiveGroup = {},
		std::optional< StringRef >	Error = std::nullopt
	)

GCCSuffix, OSSuffix & IncludeSuffix will be appended directly to the sysroot string so they must either be empty or begin with a '/' character.

This is enforced with an assert in the constructor.
