Thanks, will push.

Yeah it's always the same question.  Support for c6x has been removed
from Linux in 2021:

  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a579fcfa8e49cc77ad59211bb18bc5004133e6a0

This means that after some time, tic6x-linux-tdep.c would become
obsolete, and solib-dsbt.c too.

As for the c6x architecture itself, I find some threads that are not too
old of people trying to debug their bare metal program with GDB (through
JTAG or emulation or otherwise), for instance:
