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