<div>Hi All,</div>
<div> </div>
<div>I am trying to experiment with SCEV.</div>
<div> </div>
<div>For the below test, I want to know how I can get the max address accessed for array c.</div>
<div>Max address accessed would be </div>
<ol style="margin:0;padding-left:54pt;list-style-type:decimal;">
<li>When i loop is at its last iteration (n-1)</li><li>When k loop is at its last iteration (n-1)</li></ol>
<div> </div>
<div>How to get this in terms of SCEV.</div>
<div> </div>
<div>TEST:</div>
<div style="padding-left:36pt;">int i,j,k,sum ; </div>
<div style="padding-left:36pt;"> </div>
<div style="padding-left:36pt;">int fn(int *a, int *b, int *c, int n) </div>
<div style="padding-left:36pt;">{ </div>
<div style="padding-left:36pt;"> int i,j,k,sum ; </div>
<div style="padding-left:36pt;"> for (k = 0 ;k <n; ++k) { </div>
<div style="padding-left:36pt;"> for (j = 0 ;j <n; ++j) { </div>
<div style="padding-left:36pt;"> for (i = 0 ;i <n; ++i) { </div>
<div style="padding-left:36pt;"> a[i] = b[i] + c[i + k] ;</div>
<div style="padding-left:36pt;"> }}} </div>
