  Description     : Library with machine architecture information

This library holds machine architecture information used by the Go
toolchain. It supports the arm, arm64, ppc64 and x86 architectures. It mostly
includes functions for decoding assembly instructions.

This library is a dependency of delve (github.com/go-delve/delve, ITP in
#932835). If possible I'd like this package to be co-mantained/sponsored by the
Go Team.
