Sorry, I did not finish the gcc/binutils issues on time. 

 - For binutils patch, it is fixed by me, it is passed binutils related
   member's first checking, I guess it can correctly fix the related
   issue (although may still need improvement). It is in attachment.

 - For gcc, it is fixed by c6x gcc related member and it is integrated
   into gcc main line.  (I sent fix patch for it, but my original patch
   is incorrect).

I guess, I reported issues and sent patches were too late. And next I
should report and send fix patches in time (within 20??-??-20), so can
leave a little more time to others for reviewing and integrating
