I have downloaded the poolalloc, but it fails to compile as it requires some
files do
not exist in current llvm-2.5 version.

Should I download old version of poolalloc?

Steensgaard certainly is.
It's covered by multiple patents, in fact
Steensgaard (and MS Research) hold patents on all unification based
pointer analysis.

DSA is unification based and assumed to be under those patents also.

poolalloc is currently being developed (and should compile) against
2.6.  It will track releases not TOT for the immediate future.
