I'm not sure this is mutually exclusive with using a header file, but using
the names where possible sounds like a nice idea in principle.
There are practical issues with tags introduced in newer EABI revisions (which
may not be supported by older assemblers). However you probably need linker
support anyway and get the new assembler for free in that case. I wouldn't
put money on old binutils working reliably with new gcc in the first place.
