Detailed Description

This class understands the semantics of IR nodes.

Example: To retrieve all source var into a suif_vector:

    suif_vector<VariableSymbol*> vars;
    SemanticHelper::get_src_var( execution_Object, &vars);

To iterate over all source vars in an execution object:

    for (SemanticHelper::SrcVarIter iter(execution_object);
         iter.is_valid();
         iter.next()) {
      ... iter.current() ...

To retrieve all destination variables in a statement

     suif_vector<VariableSymbol*> vars;
     SemanticHelper::get_dst_var( statement, &vars );

To iterate over all destination variables in a statement

     for (SemanticHelper::DstVarIter iter(statement);
          iter.is_valid();
          iter.next()) {
       ... iter.current() ...

Member Function Documentation

unsigned SemanticHelper::get_src_var (const ExecutionObject * exp, suif_vector<VariableSymbol *>* lst = NULL) [static]

Collect all source variables from an ExecutionObject.

Parameters:

exp - the ExecutionObject.

lst - a vector to collect the variables.

Returns:

number of source variables found in exp.

The source variables will be appended to lst, and the number of variables appended will be returned.

unsigned SemanticHelper::get_dst_var (const Statement * stmt, suif_vector<VariableSymbol *>* lst = NULL) [static]

Collect all destination variables from a Statement.

Parameters:

exp - the Statement.

lst - a vector to collect the variables.

Returns:

number of destination variables found in exp.

The destination variables will be appended to lst, and the number of variables appended will be returned.
