If we used block copying to detect and eliminate the partially dead   store, then we should see an assignment "i = 5" somewhere in the   dump file.   Another approach would be to redirect the path from the true arm   of the first conditional so that it reaches the statement *p = 5   rather than i = 3.  *//* { dg-final { scan-tree-dump-times "i = 5" 1 "optimized" { xfail *-*-* }} } *//* { dg-final { scan-tree-dump-times "<L.*>:;\[\n\t \]*\\*p = 5" 1 "optimized" { xfail *-*-*}} } *//* { dg-final { cleanup-tree-dump "optimized" } } */
