◆ analyze()

void dt_node::analyze ( sinfo_map_t & map)
inherited 
Analyze the node and its children.

◆ 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.

◆ 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.

◆ append_op()

dt_node * dt_node::append_op ( operand * op,
dt_node * parent,
unsigned pos )
inherited 
Append OP to the decision tree.

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.

◆ append_true_op()

dt_node * dt_node::append_true_op ( operand * op,
dt_node * parent,

inherited 
Append a DT_TRUE decision tree node.

◆ 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.

◆ 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.
