            Bug ID: 32869
           Summary: PowerPC accesses
                    MachineFrameInfo::getMaxCallFrameSize() before it is
                    computed
           Product: libraries
           Version: 4.0
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: PowerPC
          Assignee: unassignedbugs at nondot.org
          Reporter: matze at braunis.de
                CC: llvm-bugs at lists.llvm.org

https://reviews.llvm.org/D32570 is adding infrastructure to detect whether
MachineFrameInfo::MaxCallFrameSize is queried before it is computed. This fails
the following PowerPC tests blocking the `assert` in the patch to be enabled:
