Detailed Description

Functions to work with machine triples.

A machine triple describes a combination of CPU type, manufacturer and operating system. A machine triple is specified as a single string of the form 'cpu-manufacturer-system' where 'system' may be the name of the operating system or just the name of the kernel. This is the same concept as the target triplet in autoconfs config.guess/config.sub. Or LLVMs triple.

The manufacturer and system part may be left out, "none" or "unknown". There is some built-in disambiguation logic that recognizes linux-gnu as the operating system even when the manufacturer was left out.

"unknown" and "elf" may be used for the operating system resulting in ELF objects being produced without assumptions about the operating system.

Examples:

Triple	CPU	Manufacturer	Operating System
i686-linux-gnu	i686	unknown	linux-gnu
i686-unknown-linux-gnu	i686	unknown	linux-gnu
x86_64-pc-mingw32	x86_64	pc	mingw32
i686-apple-darwin	x86_64	apple	darwin
x86_64-apple-darwin16.4	x86_64	apple	darwin16.4
sparc-leon-elf	sparc	leon	elf
arm-eabi	arm	unknown	eabi
arm-none-eabi	arm	unknown	eabi
mips–	mips	unknown	unknown
mips-	mips	unknown	unknown
mips	mips	unknown	unknown

Contrary to most functions, the triple manipulation functions may be used safely before ir_init() is called.
