            Bug ID: 38897
           Summary: InstCombine causes timeout after rL341674
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Scalar Optimizations
          Assignee: unassignedbugs at nondot.org
          Reporter: alina.sbirlea at gmail.com
                CC: llvm-bugs at lists.llvm.org

We're seeing compile timeouts due to huge increases in compile times caused by
https://reviews.llvm.org/rL341674. Issue goes away with the min/max changes
reverted.
Use case is code generated by Halide.
Getting a small reproduced may prove difficult, filing but without one for the
time being for awareness.
