I am no expert in this area, so please consider that I may be
misunderstanding something.
This seems a data flow analyzer for GIMPLE. So the analysis results
can be used by the FE, am I wrong?
Could it be used to propagate constant values? What about VRP in the FE?
What is the overhead involved?
I ask because I know that Clang performs data flow analysis in the FE
to provide better warnings, and Chris Lattner said that the overhead
of doing this was very low.
Cheers,
Manuel.
