ReachingDef (SgNode *defNode, Type type) | |
Creates a new reaching def. | |
bool | isPhiFunction () const |
Returns true if this is a phi function. | |
const std::map< ReachingDefPtr, std::set< FilteredCfgEdge > > & | getJoinedDefs () const |
If this is a join node (phi function), get the definitions merged. | |
SgNode * | getDefinitionNode () const |
If this is not a phi function, returns the actual reaching definition. | |
std::set< SgNode * > | getActualDefinitions () const |
Returns the actual reaching definitions at the current node, expanding all phi functions. | |
int | getRenamingNumber () const |
Get the renaming (SSA index) associated with this definition. | |
bool | isOriginalDef () const |
Returns true if this is an original definition (i.e. | |
bool | operator== (const ReachingDef &other) const |
void | setDefinitionNode (SgNode *defNode) |
Set the definition node in the AST (only valid if this is not a phi function) | |
void | addJoinedDef (ReachingDefPtr newDef, FilteredCfgEdge edge) |
Add a new join definition (only valid for phi functions). | |
void | setRenamingNumber (int n) |
Set the renaming number (SSA index) of this def. | |

const std::map< ReachingDefPtr, std::set< FilteredCfgEdge > > & ReachingDef::getJoinedDefs | ( | ) | const |
If this is a join node (phi function), get the definitions merged.
Each definition is paired with the CFG node along which it flows.
SgNode * ReachingDef::getDefinitionNode | ( | ) | const |
If this is not a phi function, returns the actual reaching definition.
If this is a phi function, returns the node where the phi function appears.
int ReachingDef::getRenamingNumber | ( | ) | const |
Get the renaming (SSA index) associated with this definition.
0 is the first value, and numbers increase monotonically with program flow.

inline |
Returns true if this is an original definition (i.e.
if p.x is defined, p.x is an original defintion and p is an expanded definition)
