Lack of architecture in gdbstub makes debugging confusing
I spent some quality time debugging GEF and came to a conclusion here:
https://github.com/hugsy/gef/issues/598#issuecomment-819174169
tldr;
* gdb_arch_name was undefined on riscv
* this bug was fixed recently via https://github.com/qemu/qemu/commit/edf647864bdab84ed4b1a4f47ea05be6bb075c69
* An undefined gdb_arch_name results in qemu's gdbstub omitting the <architecture> xml.
* gdb translates a missing <architecture> as "auto" which breaks a lot of stuff.
* tracking down where "auto" comes from is a bit confusing and time consuming.
It might be better to report a missing / blank gdb_arch_name as "<architecture>unknown</architecture>" instead of omitting the block completely.
Thanks for raising this. I have marked it as fixes as like you say it's fixed in mainline.
Is there still anything left to do here?
