Data Fields
int	left_conflict_size
short	left_conflict_subnodes_size
short	max_node_impact

Field Documentation

int allocno_hard_regs_subnode::left_conflict_size

The conflict size of conflicting allocnos whose hard register sets are equal sets (plus supersets if given node is given allocno hard registers node) of one in the given node.

short allocno_hard_regs_subnode::left_conflict_subnodes_size

The summary conflict size of conflicting allocnos whose hard register sets are strict subsets of one in the given node. Overall conflict size is left_conflict_subnodes_size

• MIN (max_node_impact - left_conflict_subnodes_size, left_conflict_size)
