 Before using the Automatic Pool Allocator, you should read the pre-release
 license in LICENSE.TXT.
+Automatic Pool Allocation is currently broken on 2.7 due to malloc and
+free instructions being removed.  Use the release_26 branch of llvm

+DSA is undergoing significant changes and may not be entirely stable or

+DSA is changed since PLDI07 in (at least) the following ways:
+1) DSA tracks types per offset.
+2) DSA does not assume that all clients will want to collapse a node if types 
+   conflict.  Many clients don't care that an offset is used as an int or a 
+   double, they just care about the points-to result.
+In Progress:
+1) DSA handles multiple entry points in a module.
+2) Optional assumption that only legal targets are called at indirect call sites
+3) Positional arguments, rather than pointer relative arguments.  This handles
+   the case where pointer and ints are assumed compatible and function pointers
+   containing them are cast freely.
