示例1: defaultFilter
// the default interesting filter
bool defaultFilter (CFGNode cfgn)
{
SgNode * node = cfgn.getNode();
assert (node != NULL) ;
//Keep the last index for initialized names. This way the definition of the variable doesn't
//propagate to its assign initializer.
// if (isSgInitializedName(node))
// {
// return (cfgn == node->cfgForEnd());
// }
// else
// return (cfgn.isInteresting());
switch(node->variantT()) {
//Keep the last index for initialized names. This way the definition of the variable doesn't
//propagate to its assign initializer.
case V_SgInitializedName:
return (cfgn == node->cfgForEnd());

// abstract memory object cannot be created for these nodes
