I have also seen a similar post by someone in mailing list asking if the reoptimizer even exists and there were no replies posted to that.

Hi Senthil,

This was a short-lived project which was implemented in the old sparc-v9 specific code generator, which has been replaced with the current retargetable and removed.  I don't recall if the reoptimizer was actually ever checked into llvm svn, but even if it was, it is surely too old to be useful.
