Thanks -- I forgot to update the dependencies in gdbserver/Makefile.in.
Maybe I should finish my patch to convert gdbserver to automake :-)
gdb has automatic dependency tracking, so that part will just work.

Yeah, it is based on my earlier patch.  It is pretty easy to apply this
and fix the conflicts though.

Sorry about that -- I meant to leave a gap for your opcode, but then I
forgot to actually do it.  I fixed this locally.

While I am working on some SystemTap-related functionality, this patch
is independent from that.

This patch just lets us translate a few more DWARF opcodes to AX.  Of
these, right now GCC only actually generates DW_OP_over.  I just looked
at GCC and it seems that the current translation code does not handle
all the uses of DW_OP_over that GCC can emit.
