Data Fields

struct ipcp_valuevalues
int values_count
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.

bool ipcp_lattice::bottom
     The value of the lattice is bottom (i.e. variable and unusable for any

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.

int ipcp_lattice::values_count
     Number of known values and types in this lattice.
