[Frama-c-discuss] Simplifying branches

I am working on a plugin which eliminates branches of code under certain
circumstances. Using a combination of constant propagation and spare
code analysis, I end up with code of the form

 if (1) {

which is technically correct, but would be more useful if it were
simplified. I notice that saving the code to disk and loading it in to
Frama-C is enough to eliminate the unnecessary "if".

Is it possible to access this simplification step from a plugin, or do I
need to write my own visitor-based implementation of it?
