I think they take the hit right now. Though profiling doesn't seem to
work on the Alpha I have here.

One alternative would be to change the following two contructs to use
memcpy() instead:

          *(char **) raw_arc[nfilled].from_pc = (char *) frompc;
          *(char **) raw_arc[nfilled].self_pc =
            (char *)_gmonparam.tos[to_index].selfpc;

That way we preserve the binary format and I don't think the overhead
is noticable on other architectures presuming gcc will catch the fixed
sized memcpy's.

If thats ok with you, I'll cook up a patch straight away.
