I've now committed a patch to mainline GDB that significantly improves
backtraces for Thumb-2 code even in the absence of DWARF CFI debug info. This
will still not handle absolutely all cases (e.g. hand-written assembler
routines that don't follow usual conventions), but should still help quite a
bit:
