    For me, I get the latest gcc version and binutils source code, and fix 2
    bugs (one for gas, which always generate core dump, the other for gcc
    c-decl, fix it together with the other gcc members).

    And I only finish compiling raw cross-compiler (--without-headers),
    after make some patches, can let score pass allmodconfig.

    At present, it seems the score cross-compiler still contents some issue
    which I shall try to analyse (it is about link symbols), and maybe need
    communicate with gcc/binutils members.


    At present, the related score maintainers are still active in upstream
    kernel, so we also need the related maintainers' ideas and suggestions.


    Thanks
