/* The assignment "i = 3" is partialy dead. Our DSE pass doesn't handle
detection of partially dead assignments.
There's two outputs which would indicate that the optimization was
performed.
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. */
