Any LLVM passes for integers type compaction?

A few colleagues of mine implemented an inter-procedural range analysis algorithm for LLVM 2.7 a few years back.
Their paper (see http://homepages.dcc.ufmg.br/~fernando/publications/papers/SBLP12_victor.pdf) states a 13-14% reduction in variable size
for the SPEC CPU2006 benchmarks and 36% for the Stanford benchmarks.

Dear Henrique,

Thanks for reply, I think I saw this project before. We have an LLVM-based GPU toolchain, where variable size is usually one of the major performance factors.
