22 /// Triple - Helper class for working with target triples.
24 /// Target triples are strings in the canonical form:
25 /// ARCHITECTURE-VENDOR-OPERATING_SYSTEM
27 /// ARCHITECTURE-VENDOR-OPERATING_SYSTEM-ENVIRONMENT
29 /// This class is used for clients which want to support arbitrary
30 /// target triples, but also want to implement certain special
31 /// behavior for particular targets. This class isolates the mapping
32 /// from the components of the target triple to well known IDs.
34 /// At its core the Triple class is designed to be a wrapper for a triple
35 /// string; the constructor does not change or normalize the triple string.
36 /// Clients that need to handle the non-canonical triples that users often
37 /// specify should use the normalize method.
39 /// See autoconf/config.guess for a glimpse into what triples look like in
