Usage: llvm-xray extract <object file> [-o <filename or '-'>] The tool gets the XRay instrumentation map from an object file and turns it into YAML. We first support ELF64 sleds on x86_64 binaries, with provision for supporting other supported platforms and formats later. This is the first of a many-part change to fully implement the `llvm-xray` tool. We also define a subcommand registration and dispatch mechanism to be used by other further subcommand implementations for llvm-xray.
