Thanks for the information.
There are unofficial patches to both gcc and gdb to support 6809. Neither of
them support DWARF.
As you said, MAME could in theory just come up with a register mapping, and
compiler writers (e.g., CMOC for 6809) would have to adhere to that mapping to

Hi David,
There's no standard ABI document (that I could find). You might want to look in
the GDB sources on the off chance that it supported at some point.
Ultimately, the thing that matters is how the compilers you are using numbers
the registers. There is a decent description of the micropro
