Detailed Description

Triple - Helper class for working with autoconf configuration names. For historical reasons, we also call these 'triples' (they used to contain exactly three fields).

Configuration names are strings in the canonical form: ARCHITECTURE-VENDOR-OPERATING_SYSTEM or ARCHITECTURE-VENDOR-OPERATING_SYSTEM-ENVIRONMENT

This class is used for clients which want to support arbitrary configuration names, but also want to implement certain special behavior for particular configurations. This class isolates the mapping from the components of the configuration name to well known IDs.

At its core the Triple class is designed to be a wrapper for a triple string; the constructor does not change or normalize the triple string. Clients that need to handle the non-canonical triples that users often specify should use the normalize method.

See autoconf/config.guess for a glimpse into what configuration names look like in practice.

Triple::Triple ( const Twine & Str ) [explicit]

Construct a triple from the string representation provided.

This stores the string representation and parses the various pieces into enum members.

Triple::Triple	(	const Twine &	ArchStr,
		const Twine &	VendorStr,
		const Twine &	OSStr
