public boolean invalidate(FullInterpreterContext fic)

Overrides org.jruby.ir.passes.CompilerPass.invalidate.

Doc from org.jruby.ir.passes.CompilerPass.invalidate.

The data that this pass is responsible for will get invalidated so that if this pass is then executed it will generate new pass data. Note that some data will destructively manipulate dependent compiler pass data. In that case, the pass may wipe more than just it's data. In that case, an execute() should still rebuild everything fine because all compiler passes list their dependencies.

Parameters
fic:FullInterpreterContext

is where the pass stores its data.

Returns:boolean

true if invalidation succeeded, false otherwise.
