Member Function Documentation

clone()

opt_pass * pass_walloca::clone ( )

inlinefinaloverridevirtual

Most passes are single-instance (within their context) and thus don't
need to implement cloning, but passes that support multiple instances
*must* provide their own implementation of the clone method.

Handle this by providing a default implemenation, but make it a fatal
error to call it.   

Reimplemented from opt_pass.
