Nate Begeman 49e38c2185 Initial implementation of the strength reduction for GEP instructions in ... loops. This optimization is not turned on by default yet, but may be run with the opt tool's -loop-reduce flag. There are many FIXMEs listed in the code that will make it far more applicable to a wide range of code, but you have to start somewhere :) This limited version currently triggers on the following tests in the MultiSource directory: pcompress2: 7 times cfrac: 5 times anagram: 2 times ks: 6 times yacr2: 2 times llvm-svn: 17134		2004-10-18 21:08:22 +00:00
