History
Chris Lattner 8408add00a Add optimizations: 
- (A & C1)+(B & C2) -> (A & C1)|(B & C2) iff C1&C2 == 0
 - (A & C1)^(B & C2) -> (A & C1)|(B & C2) iff C1&C2 == 0

README.txt 

This directory contains test cases for the instcombine transformation.  The
dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
