[PATCH] D18777: [ValueTracking] An improvement to IR ValueTracking on Non-negative Integers

[Li Huang via llvm-commits]

lihuang added a comment.

The problem is in indvarsimplify, this patch results in redundant trunc/sext that should be eliminated by indvarsimplify but not, causing the loop in TSVC/s174 not vectorizable. I will submit a fix for review.
