Detailed Description

Lattice of tree values with an offset to describe a part of an
aggregate.   

Member Function Documentation

add_value()

bool ipcp_lattice< tree >::add_value ( tree newval, cgraph_edge * cs, ipcp_value< tree > * src_val = NULL, int src_idx = 0, HOST_WIDE_INT offset = -1, ipcp_value< tree > ** val_p = NULL, unsigned same_lat_gen_level = 0 )

inherited

Try to add NEWVAL to LAT, potentially creating a new ipcp_value for it.  CS,
SRC_VAL SRC_INDEX and OFFSET are meant for add_source and have the same
meaning.  OFFSET -1 means the source is scalar and not a part of an
aggregate.  If non-NULL, VAL_P records address of existing or newly added
ipcp_value.

If the value is generated for a self-recursive call as a result of an
arithmetic pass-through jump-function acting on a value in the same lattice,
SAME_LAT_GEN_LEVEL must be the length of such chain, otherwise it must be
zero.  If it is non-zero, PARAM_IPA_CP_VALUE_LIST_SIZE limit is ignored.   

is_single_const()

bool ipcp_lattice< tree >::is_single_const ( )

inlineinherited

Return whether LAT is a lattice with a single constant and without an
undefined value.   

print()

void ipcp_lattice< tree >::print ( FILE * f, bool dump_sources, bool dump_benefits )

inherited

Print a lattice LAT to F.   

set_contains_variable()

bool ipcp_lattice< tree >::set_contains_variable ( )

inlineinherited

Mark lattice as containing an unknown value and return true if it previously
was not marked as such.   

set_to_bottom()

bool ipcp_lattice< tree >::set_to_bottom ( )

inlineinherited

Set lattice LAT to bottom and return true if it previously was not set as
such.
