| AnalysisID | getPassID () const |
| getPassID - Return the PassID number that corresponds to this pass. | |
| virtual bool | doFinalization (Module &) |
| doFinalization - Virtual method overriden by subclasses to do any necessary clean up after all passes have run. | |
| virtual void | print (raw_ostream &OS, const Module *M) const |
| print - Print out the internal state of the pass. | |
| void | dump () const |
| virtual void | preparePassManager (PMStack &) |
| Check if available pass managers are suitable for this pass or not. | |
| void | setResolver (AnalysisResolver *AR) |
| AnalysisResolver * | getResolver () const |
| virtual void | releaseMemory () |

getPassName - Return a nice clean name for a pass.
This usually implemented in terms of the name that is registered by one of the Registration templates, but can be overloaded directly.
