| <div class="block">This Inter Procedural Analysis (IPA) serves two major purposes: |
| 1) Inter-Procedure Analysis: propagate statistics from calling program into |
| functions and back into main program. This is done recursively for nested |
| function invocations. |
| 2) Intra-Procedural Analysis: propagate statistics across hop dags of subsequent |
| statement blocks in order to allow chained function calls and reasoning about |
| changing sparsity etc (that requires the rewritten hops dag as input). This |
| also includes control-flow aware propagation of size and sparsity. Furthermore, |
| it also serves as a second constant propagation pass. |
| |
| Additionally, IPA also covers the removal of unused functions, the decision on |
| recompile once functions, the removal of unnecessary checkpoints, and the |
| global removal of constant binary operations such as X * ones.</div> |
