Member Function Documentation

op_or_null()

tree gimple_match_op::op_or_null ( unsigned int i ) const

inline

Return the value of operand I, or null if there aren't that many
operands.   

References i, NULL_TREE, num_ops, and ops.

resimplify()

bool gimple_match_op::resimplify	(	gimple_seq *	seq,
		tree(*)(tree)	valueize )

Match and simplify the toplevel valueized operation THIS.
Replaces THIS with a simplified and/or canonicalized result and
returns whether any change was made.
