            Bug ID: 51434
           Summary: test-release.sh fails to build binary on PowerPC for
                    13.0.0-rc1
           Product: new-bugs
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: release blocker
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org

This is because flang is now also built and tested. We identified the issue to
be related to CTR loops.

The actual error: 
UNREACHABLE executed at
/home/conanap/upload/rc1/llvm-project/llvm/lib/Target/PowerPC/PPCCTRLoops.cpp:182!

We have an idea of how to fix, but for the binaries of rc1 we will be uploading
sans flang. This issue exists for both Ubuntu and RHEL.
