Detailed Description
Class to compute and manage control dependences on an edge-list.
Constructor & Destructor Documentation
| control_dependences::control_dependences | ( | edge_list * | edges | ) |
Record all blocks' control dependences on all edges in the edge list EL, ala Morgan, Section 3.6.
| control_dependences::~control_dependences | ( | ) |
Free control dependences and the associated edge list.

Clear all control dependences for block BB.

Determine all blocks' control dependences on the given edge with edge_list EL index EDGE_INDEX, ala Morgan, Section 3.6.
For abnormal edges, we don't make current_block control
dependent because instructions that throw are always necessary
anyway.
| edge control_dependences::get_edge | ( | int | i | ) |
Returns the edge with index I from the edge list.

| bitmap control_dependences::get_edges_dependent_on | ( | int | i | ) |
Returns the bitmap of edges the basic-block I is dependent on.
