22/// A plug-in interface definition class for JIT loaders.
23///
24/// Plugins of this kind listen for code generated at runtime in the target.
25/// They are very similar to dynamic loader, with the difference that they do
26/// not have information about the target's dyld and that there may be
27/// multiple JITLoader plugins per process, while there is at most one
28/// DynamicLoader.
