Can objdump un-mangle names of C++ template functions?

Question

I have a C++ object file that contains instantiations of some C++ template functions. The object file in question instantiates the same function for a few different combinations of template parameters. I'm trying to debug a problem and would like to look at the disassembly of a specific instantiation of the template function (that is, I know the template parameters for the function that I want to examine). I would typically do this using objdump to disassemble the object file, but it (at least by default) isn't able to de-mangle the C++ function names. Is there any way to do this? The object files were created using gcc 4.6.1.
