analyze()

void dt_node::analyze ( sinfo_map_t & map )

inherited

Analyze the node and its children.   

References as_a(), i, info, map, MAX, NULL, sinfo::s, and si.

append_match_op()

dt_node * dt_node::append_match_op ( operand * op, dt_operand * match_dop, dt_node * parent, unsigned pos )

inherited

Append a DT_MATCH decision tree node.   

References as_a().

Referenced by decision_tree::insert_operand().

append_node()

dt_node * dt_node::append_node ( dt_node * n )

inherited

Append N to the decision tree if it there is not already an existing
identical child.   

References decision_tree::find_node(), and dt_node::level.

append_op()

dt_node * dt_node::append_op ( operand * op, dt_node * parent, unsigned pos )

inherited

Append OP to the decision tree.   

References safe_as_a().

Referenced by decision_tree::insert_operand().

append_simplify()

dt_node * dt_node::append_simplify ( simplify * s, unsigned pattern_no, dt_operand ** indexes )

inherited

Append S to the decision tree.   

References dyn_cast(), i, operand::location, simplify::match, print_operand(), s, verbose, and warning_at().

Referenced by decision_tree::insert().

append_true_op()

dt_node * dt_node::append_true_op ( operand * op, dt_node * parent, unsigned pos )

inherited

Append a DT_TRUE decision tree node.   

References safe_as_a().

gen()

void dt_simplify::gen ( FILE * f, int indent, bool gimple, int depth )

finaloverridevirtual

Generate code for the '(if ...)', '(with ..)' and actual transform
step of a '(simplify ...)' or '(match ...)'.  This handles everything
that is not part of the decision tree (simplify->match).   

Reimplemented from dt_node.

References fprintf_indent(), gcc_unreachable, get_name(), i, is_a(), and output_line_directive().

gen_1()

void dt_simplify::gen_1	(	FILE *	f,
		int	indent,
		bool	gimple,
		operand *	result )

Generate code for the '(if ...)', '(with ..)' and actual transform
step of a '(simplify ...)' or '(match ...)'.  This handles everything
that is not part of the decision tree (simplify->match).
Main recursive worker.   

References as_a(), dyn_cast(), fail_label, capture_info::force_no_side_effects, fprintf_indent(), i, capture_info::info, NULL, output_line_directive(), simplify::SIMPLIFY, verbose, and warning_at().

Referenced by decision_tree::gen().

gen_kids()

void dt_node::gen_kids ( FILE * f, int indent, bool gimple, int depth )

inherited

Generate matching code for the children of the decision tree node.
