  New Revision: 12422

  Modified files:
    trunk/ChangeLog
    trunk/insnhelper.h
    trunk/insns.def

  Log:
    * insnhelper.h (INC_SP): shouldn't cast ``x'' to unsigned type because
      it might be a negative value.
    
    * insnhelper.h, insns.def: shoudn't use unary minus operator in index
      operator. some compilers (such as VC++8 x64) cannot deal it with
      expected way.
