            Bug ID: 27479
           Summary: AArch64 make check has a few of machine verifier
                    errors
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: AArch64
          Assignee: unassignedbugs at nondot.org
          Reporter: qcolombet at apple.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

Switching the machine verifier ON by default (lib/CodeGen/Passes.cpp then
change the default value of the cl::opt related to the machine verifier) leads
to a few of machine verifier errors for make check:
    LLVM :: CodeGen/AArch64/aarch64-tbz.ll
    LLVM :: CodeGen/AArch64/arm64-AdvSIMD-Scalar.ll
    LLVM :: CodeGen/AArch64/nzcv-save.ll

This may be latent bug.
