I don't know much about these old CPUs, but it looks like GDB supports the 6811, and the source file does talk about DWARF: https://gitlab.com/gnutools/binutils-gdb/-/blob/420d030e88d2c8bbad6044278000fbd9efbf65d9/gdb/m68hc11-tdep.c Are the 6809 and 6811 close enough that they could use the same register numbering? In any case, I think it would be super useful to have a page on the DWARF wiki to document where to find the ABI references (including the register numbering) for as many architectures as possible. And if there's no definitive reference, like in this case, we can still mention that "this project here" came up with some numbering. That would encourage others to re-use the numbering and it would become a defacto standard.
