Field Documentation

bool ipcp_lattice::bottom

inherited

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

inherited

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

Referenced by pop_node_from_stack().

struct ipcp_agg_lattice* ipcp_agg_lattice::next

Next element of the linked list.

Referenced by move_binfos_to_values(), and set_check_aggs_by_ref().

HOST_WIDE_INT ipcp_agg_lattice::offset

Offset that is being described by this lattice.

Referenced by move_binfos_to_values().

HOST_WIDE_INT ipcp_agg_lattice::size

Size so that we don't have to re-compute it every time we traverse the list. Must correspond to TYPE_SIZE of all lat values.

struct ipcp_value* ipcp_lattice::values

inherited

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

inherited

Number of known values and types in this lattice.
