[LLVMdev] 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.
Check out http://code.google.com/p/range-analysis/ if you're interested and feel free to email me if you have any questions.

Subject: [LLVMdev] Any LLVM passes for integers type compaction?
I'm wondering if anybody is working on optimization passes that could use smaller integer types for variables that are known to have values within smaller type range?
