Synopsis: missed warning and optimization
State-Changed-From-To: open->suspended
State-Changed-By: rth
State-Changed-When: Tue Jan 16 02:51:49 2001
State-Changed-Why:
(1) The variable X is not unused -- you assigned to it.
(2) The loop is removed in current snapshots with
-fssa -fdce, which is not the default at -ON
because of various problems remaining in that
code wrt unfriendly constructs generated by some
ports. Some day that will get fixed.
