As far as the dwarf2out.c bits go, I think the original dbx_reg_number

gcc_assert (regno != INVALID_REGNUM);

So please ignore that stupid suggestion. The comments about the MIPS

Here is a new patch. I made the MIPS changes and I also changed some
code in dwarf2out.c. I was making some calls to

This is my attempt to fix PR 54061, a bug where GCC aborts while trying to
put out debug information for a co-processor register. My understanding is
that gdb cannot access the coprocessor registers and so there is no valid
debug information that can be put out for this case. So my fix is to

I think you need a way to tell a bad register from a good register
which doesn't have DWARF register number.
Something like
#define IGNORED_DWARF_REGNUM(INVALID_REGNUM - 1)
The other option would be to have a new macro

Here is a patch using your IGNORED_DWARF_REGNUM idea.
