If x is known to have the range [a, b), in a loop predicated by (icmp ne x, a) its range can be sharpened to [a + 1, b). Get ScalarEvolution and hence IndVars to exploit this fact. This change triggers an optimization to widen-loop-comp.ll, so it had to be edited to get it to pass. This change was originally landed in r219834 but had a bug and broke ASan. It was reverted in r219878, and is now being re-landed after fixing the original bug. phabricator: http://reviews.llvm.org/D5639 reviewed by: atrick git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@221839 91177308-0d34-0410-b5e6-96231b3b80d8 |
