[PATCH] D22377: [SCEV] trip count calculation for loops with unknown stride

Hi all,

I have a fix for the issue. The max backedge taken count was incorrectly set to 1 for loops with unknown strides which resulted in LSR perofming the wrong transformation. I verified that we generate identical assembly code for the reproducer without my patch and with my patch + additional fix.

It looks like I am not able to upload the diff to this review since it is closed. Do I have to open a new review?

Thanks,
Pankaj
