[Frama-c-discuss] About the slicing plugin. (slicing speed on slicing zones)

I am sorry for forgetting to report the results.
These two solutions are equivalent.
After rechecking my code, the low speed of slicing is caused by slicing too
many stmts.
I also find that slicing stmts is much more slower than slicing
locations.zone.
