I think few ports of GDB get right--if you are popping a frame
which does not save some register that *is* saved by a more inner
frame (such a frame will never be a dummy frame because dummy
frames save all registers). Rewriting pop_frame to use
get_saved_register would solve this problem and also get rid of the
ugly duplication between sparc_frame_find_saved_regs and
get_saved_register.
frames save all registers).
NOTE: cagney/2003-03-12: Since pop_frame has been rewritten to use
frame_unwind_register() the need for this function is questionable.
Stores, into an array of CORE_ADDR,
the addresses of the saved registers of frame described by FRAME_INFO.
