Subject: [PATCH] Solve the problem of core dumped when using large-scale data
 in benchmark test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

E.g ：  when running test calse such as below in benchmark:
./dgemv.goto 100000 100000 100000
From : 100000  To : 100000 Step = 100000 Trans = 'N' Inc_x = 1 Inc_y = 1 Loops = 1
   SIZE       Flops
 100000 : Segmentation fault (core dumped)
Because j+i*m has exceeded the maximum range of int
