    Hi,
        While writing kernel code what is the correct way to find out if the
    kernel is being compiled with frame pointer?

    Is the following code correct?

    #ifdef CONFIG_FRAME_POINTER
            code assuming frame pointer
    #else
            code assuming no frame pointer

    The top level Makefile that comes with the standard kernels (the ones
    which can be downloaded from kernel.org etc.) adds -fomit-frame-pointer to
    CFLAGS by default and it does not have something like

    ifdef CONFIG_FRAME_POINTER
    CFLAGS += -fomit-frame-pointer
    endif

    Is CONFIG_FRAME_POINTER a part of some external patch?
    If yes, then is there a way to find the above in the standard
    kernels?

    What about CONFIG_KDB_FRAMEPTR? Is it correct to use this in a standard
    kernel to find whether the kernel is being compiled with frame pointer?

    Thanks and Regards,
    Sushil.
