            Bug ID: 42671
           Summary: Add support for response files in llvm-strip and
                    llvm-objcopy
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: llvm-objcopy/strip

Most LLVM tools support response files (i.e. something like llvm-readelf
@response.txt, where response.txt contains a list of inputs and options for the
tool). However, llvm-objcopy and llvm-strip do not. I think this is an artifact
of them using tablegen to build. I think it's relatively easy to fix - the cl
namespace provides ExpandResponseFiles, which is used e.g. by LLD to support
them.
