poolalloc and steensgaard

Dear llvm developers:

Just find that the steensgaard alias analysis pass is removed from the latest poolalloc lib.
So if i want to use this pass, can i use the Steensgaard source code from some previous version and compile it on the current poolalloc code base with some possible modifications?

Or are there any better alternatives?


Stepping up a level, what are you trying to achieve by using the Steensgaard AA code from pooalloc? Perhaps there is a better way to do what you need to do. Regards, John Criswell
