Field Documentation

tree ao_ref_s::base 
     The following fields are the decomposed reference as returned
     by get_ref_base_and_extent.  
     The base object of the memory reference or NULL_TREE if all of
     the following fields are not yet computed.

alias_set_type ao_ref_s::base_alias_set 
     The alias set of the base object or -1 if not yet computed.

Referenced by debug_points_to_info_for().

HOST_WIDE_INT ao_ref_s::max_size 
     The maximum possible extent of the access or -1 if unconstrained.

HOST_WIDE_INT ao_ref_s::offset 
     The offset relative to the base.

tree ao_ref_s::ref 
     The original full memory reference tree or NULL_TREE if that is
     not available.

Referenced by debug_points_to_info_for(), and refs_independent_p().

alias_set_type ao_ref_s::ref_alias_set 
     The alias set of the access or -1 if not yet computed.
HOST_WIDE_INT ao_ref_s::size 
     The size of the access.

Referenced by vn_reference_lookup_3().

bool ao_ref_s::volatile_p 
     Whether the memory is considered a volatile access.
