            Bug ID: 49679
           Summary: DAGToDAGISel pass confusion
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: AMDGPU
          Assignee: unassignedbugs at nondot.org
          Reporter: karl-johan.karlsson at ericsson.com
                CC: llvm-bugs at lists.llvm.org

When specifying x86-64 (or any other backend) the -debug-pass=Arguments still
prints amdgpu-isel. This is a bit confusing. A consequence of this is that we
can't reliably use -stop-before or run-pass for the pass.

$ llc -mtriple x86_64-unknown-unknown -O3 /dev/null -debug-pass=Arguments -o
/dev/null 2>&1 | grep -o amdgpu-isel
amdgpu-isel
