           Summary: AArch64 accesses
                    MachineFrameInfo::getMaxCallFrameSize() before it is
                    computed
           Product: libraries
           Version: 4.0
          Hardware: PC

            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: AArch64

https://reviews.llvm.org/D32570 is adding infrastructure to detect whether
MachineFrameInfo::MaxCallFrameSize is queried before it is computed. This fails
the following aarch64 tests blocking the `assert` in the patch to be enabled:

    LLVM :: CodeGen/AArch64/arm64-tls-darwin.ll
    LLVM :: CodeGen/AArch64/cxx-tlscc.ll
