        * dwarf2cfi.c (DEFAULT_INCOMING_FRAME_SP_OFFSET): Define to
        INCOMING_FRAME_SP_OFFSET if not defined.
        (scan_trace): Add ENTRY argument.  If true and
        DEFAULT_INCOMING_FRAME_SP_OFFSET != INCOMING_FRAME_SP_OFFSET,
        emit a note to adjust the CFA offset.
        (create_cfi_notes): Adjust scan_trace callers.
        (create_cie_data): Use DEFAULT_INCOMING_FRAME_SP_OFFSET rather than
        INCOMING_FRAME_SP_OFFSET in the CIE.
        * config/i386/i386.h (DEFAULT_INCOMING_FRAME_SP_OFFSET): Define.
        * config/stormy16/stormy16.h (DEFAULT_INCOMING_FRAME_SP_OFFSET):
        Likewise.
        * doc/tm.texi.in (DEFAULT_INCOMING_FRAME_SP_OFFSET): Document.
        * doc/tm.texi: Regenerated.
