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.


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.
