            Bug ID: 44628
           Summary: Large increase in AMDGPU tblgen build times
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: AMDGPU
          Assignee: unassignedbugs at nondot.org
          Reporter: llvm-dev at redking.me.uk
                CC: llvm-bugs at lists.llvm.org, Matthew.Arsenault at amd.com
            Blocks: 28222

I've noticed -gen-dag-isel in particular seems to take a lot longer, and is by
far the worst culprit in *gulp* debug tblgen builds
