            Bug ID: 22467
           Summary: Win64 prologues with frame pointers must set RBP last
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: X86
          Assignee: unassignedbugs at nondot.org
          Reporter: rnk at google.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

The tried and true x86 prologue of "push %rbp ; mov %rsp, %rbp" cannot be
described correctly by Win64 unwind info opcodes. Basically, the SETFRAME
opcode has to come last, and it's the second instruction we emit.
