            Bug ID: 27480
           Summary: ARM make check has a bunch of machine verifier errors
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: ARM
          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 bunch of machine verifier errors for make check:
    LLVM :: CodeGen/ARM/Windows/chkstk-movw-movt-isel.ll
    LLVM :: CodeGen/ARM/Windows/chkstk.ll
    LLVM :: CodeGen/ARM/Windows/dbzchk.ll
    LLVM :: CodeGen/ARM/Windows/division.ll
    LLVM :: CodeGen/ARM/Windows/no-aeabi.ll
    LLVM :: CodeGen/MIR/ARM/ARMLoadStoreDBG.mir
    LLVM :: CodeGen/MIR/ARM/sched-it-debug-nodes.mir
