22 /// Triple - Helper class for working with autoconf configuration names. For
23 /// historical reasons, we also call these 'triples' (they used to contain
24 /// exactly three fields).
26 /// Configuration names are strings in the canonical form:
27 /// ARCHITECTURE-VENDOR-OPERATING_SYSTEM
29 /// ARCHITECTURE-VENDOR-OPERATING_SYSTEM-ENVIRONMENT
31 /// This class is used for clients which want to support arbitrary
32 /// configuration names, but also want to implement certain special
33 /// behavior for particular configurations. This class isolates the mapping
34 /// from the components of the configuration name to well known IDs.
36 /// At its core the Triple class is designed to be a wrapper for a triple
37 /// string; the constructor does not change or normalize the triple string.
38 /// Clients that need to handle the non-canonical triples that users often
39 /// specify should use the normalize method.
41 /// See autoconf/config.guess for a glimpse into what configuration names
42 /// look like in practice.
