We are working on an analysis for identifying the class of an object flow

flow sensitive de-virtualization (i.e. replacing a virtual function call by
a call to the
function of a known class in the hierarchy). This is a regular ipa pass. It
find outs the
class of an object at point of creation and then propagates it.

Most of this is already in GCC 5 and above.  Including the IPA pass.
Have you looked into that pass yet?


From what I have read, it involves flow insensitive analysis whereas we are looking at flow sensitive analysis.
