        (current_fde): Remove.  Replace all users with cfun->fde.
        (output_call_frame_info): Use FOR_EACH_VEC_ELT over fde_vec.
        (size_of_aranges, dwarf2out_finish): Likewise.
        (dwarf2out_alloc_current_fde): Break out from ...
        (dwarf2out_begin_prologue): ... here.
        (dwarf2out_frame_init): Remove.
        * dwarf2cfi.c: Update all users of current_fde.
        (dwarf2out_frame_init): Rename from dwarf2cfi_frame_init.
        * dwarf2out.h: Update decls.
