Detailed Description

An instance of a pass.  This is also "pass_data" to minimize the
changes in existing code.

clone()

opt_pass * opt_pass::clone ( )

virtual

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 in pass_array_bounds, and pass_walloca.

execute()

unsigned int opt_pass::execute ( function * fun )
