AltArch maps arch values to an alternative representations - 386 -> x32 - amd64 -> x64 - arm -> arm32 - arm64 -> arm64 (noop).

MustParse is like Parse, but panics isth string cannot be parsed.

NormArch maps alternative arch representations to GO-compatible arch names.

Parse parses a string into Pair.

ParseList parses one or more strings with comma-separated list of arches into a set of pairs, also supports some predefined values.

SameArch checks if the two arch names refer to the same arch.

This returns runtime.GOOS, runtime.GOARCH pair, This is the pair for which the compiler is currently building.

ErrInvalid is returned when a string representation of Pair is invalid.

Pair contains a OS, architecture pair, typically pulled from runtime.GOOS and runtime.GOARCH.
