            Bug ID: 35856
           Summary: llvm-objdump can't handle a mix of object formats
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: llvm-objdump
          Assignee: unassignedbugs at nondot.org
          Reporter: al.grant at arm.com
                CC: llvm-bugs at lists.llvm.org

Given a mix of object formats, say

  llvm-objdump x86.o arm.o

llvm-objdump will infer the target triple from the first object,
update the command-line option variable, and then use that to control
disassembly of the second object - so it gets it wrong.

All that appears to be needed to have llvm-objdump deal gracefully
with a mix of object types is to keep the inferred triple (and
anything derived from it) local to the processing of each object,
rather than updating the global command-line option variable.
