Suyog Sarda c9ea25fc51 This patch implements optimization as mentioned in PR19753: Optimize comparisons with "ashr/lshr exact" of a constanst. ... It handles the errors which were seen in PR19958 where wrong code was being emitted due to earlier patch. Added code for lshr as well as non-exact right shifts. It implements : (icmp eq/ne (ashr/lshr const2, A), const1)" -> (icmp eq/ne A, Log2(const2/const1)) -> (icmp eq/ne A, Log2(const2) - Log2(const1)) Differential Revision: http://reviews.llvm.org/D4068 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@213678 91177308-0d34-0410-b5e6-96231b3b80d8		2014-07-22 19:19:36 +00:00
