Detailed Description

Simplified and cached information about a memory reference tree.
Used by the alias-oracle internally and externally in alternate
interfaces.

Member Function Documentation

◆ max_size_known_p()

bool ao_ref::max_size_known_p ( ) const

inline

Return true if the maximum size is known, rather than the special -1
marker.
