Conditions that are interesting for function body are collected into CONDS vector. They are of simple for function_param OP VAL, where VAL is IPA invariant. The conditions are then referred by predicates.

Field Documentation

ENUM_BITFIELD (tree_code) code unsigned condition::agg_contents

Set if the used data were loaded from an aggregate parameter or from data received by reference.

unsigned condition::by_ref

If agg_contents is set, this differentiates between loads from data passed by reference and by value.

Referenced by set_hint_predicate().

HOST_WIDE_INT condition::offset

If agg_contents is set, this is the offset from which the used data was loaded.

Referenced by set_hint_predicate().

int condition::operand_num

Referenced by evaluate_predicate(), and set_hint_predicate().
