--- Comment #4 from Eric <ericns1 at spirilis dot net> ---
Okay, I think I've figured out what I'm looking at here.

The inheritance has to do with the use of virtual functions - so the JSR vs BSR
argument in here is a red herring, overridden virtual functions use JSR because
it's doing a lookup inside the vtable.

GCC 5.2.0 is providing the vtable with a general gcc/newlib-derived ldscript I
have.

The GNURX example which failed on my RX210, otoh, does not appear to have the
vtable when I disassemble using rx-elf-objdump -C -DS and search for 'vtable'. 
Probably an incomplete ldscript there.  Need to figure out what sections vtable
et al fall under... then I will go complain to the KPIT folks.

Sorry for the wild goose chase :-)
