class ExternalToolHook extends AnyRef
This is an external tool hook, it allows an external tool such as YourKit or JProfiler to instrument a particular phase of the compiler. Profilers have hooks to allow starting and stopping profiling on a given method invocation.
To use add -Yprofile-external-tool (defaults to typer) or -Yprofile-external-tool:<phase> (for a specific compiler phase) to the compiler flags.
'before' will be called at the start of the target phase and 'after' at the end, allowing custom profiling to be triggered.
