struct ipcp_value *	values

bool	contains_variable
bool	bottom

Detailed Description

   Lattice describing potential values of a formal parameter of a function, or
   a part of an aggreagate.  TOP is represented by a lattice with zero values
   and with contains_variable and bottom flags cleared.  BOTTOM is represented
   by a lattice with the bottom flag set.  In that case, values and
   contains_variable flag should be disregarded.

Field Documentation

bool ipcp_lattice::bottom

     The value of the lattice is bottom (i.e. variable and unusable for any
     propagation).

Referenced by add_scalar_value_to_lattice(), ipa_get_scalar_lat(), and move_binfos_to_values().

bool ipcp_lattice::contains_variable

     The lattice contains a variable component (in addition to values).

Referenced by pop_node_from_stack().

struct ipcp_value* ipcp_lattice::values

     The list of known values and types in this lattice.  Note that values are
     not deallocated if a lattice is set to bottom because there may be value
     sources referencing them.

Referenced by add_value_to_lattice(), and move_binfos_to_values().

int ipcp_lattice::values_count

     Number of known values and types in this lattice.
