Yep.  The dwarf2 info needs to be extended to know about STACK_BIAS.
Currently the code assumes that the CFA corresponds to the value of $sp
after the epilogue, which is not true in your case.  That may not be
important, since the SPARC always uses a frame pointer, but you probably
need to define INCOMING_FRAME_SP_OFFSET to STACK_BIAS.  That could
reasonably be a default in dwarf2out.c.
