* dbxread.c (process_one_symbol): Handle stabs-in-som just like

Browse Source 
stabs-in-elf.
        (pastab_build_psymtabs): Likewise.

        * hppa-tdep.c: Change all comments to reference %r3 or frame pointer
        rather than %r4.
        (frame_chain, skip_prologue, dig_rp_from_stack): Handle %r3 as the
        frame pointer.

        * config/pa/tm-hppa.h (FP_REGNUM): Define as %r3.
        (FIND_FRAME_SAVED_REGS): Handle %r3 as frame pointer.
        (CALL_DUMMY): Likewise.
