I see that there are two functions in your code that are O(n^2) in
number of instructions of the program: getCandidatePairs and
buildDepMap. I think that you could make these two functions faster
if you work on some form of factored def-use chains for memory, like
the VUSE/VDEFs of GCC.
I was trying to find a similar representation in LLVM: isn't there already
a virtual SSA representation for memory references in LLVM?
