[PATCH] D19266: [SCEV] Improve the run-time checking of the NoWrap predicate

[silviu.baranga@arm.com via llvm-commits]

sbaranga updated this revision to Diff 54643.
sbaranga added a comment.

Only compare the step with 0 when we need to truncate the backedge taken count.
Otherwise, the case where the step is 0 is correctly handled.

Address the other comments received in the review.
