+
+ * sem_warn.adb (Check_Infinite_Loop_Warning): Catch cases like
+ "while X /= null loop" where X is unchanged inside the loop. We were
+ not warning in this case, because of the pointers -- we feared that the
+ loop variable could be updated via a pointer, if there are any pointers
+ around the place. But that is impossible in this case.
+
+ * sem_util.adb (May_Be_Lvalue): This routine was overly pessimistic in
+ the case of dereferences. In X.all, X cannot be an l-value. We now
+ catch that case (and implicit dereferences, too).

+ (Analyze_Package_Instantiation): If generic unit in child instance is
+ the same as generic unit in parent instance, look for an outer homonym
+ to locate the desired generic.
+
+2009-04-15 Bob Duff <duff@adacore.com>
+
+ * sem_ch5.adb (Analyze_Loop_Statement): Don't check for infinite loop
+ warnings unless the loop comes from source, because checking generated
+ loops is a waste of time, and makes it harder to debug
+ Check_Infinite_Loop_Warning.
+
+ * sem_warn.adb (Check_Infinite_Loop_Warning): If the local variable
+ tested in the while loop is a renaming, do not warn. Otherwise, we get
+ false alarms, because it's usually renaming something that we can't
+ deal with (an indexed component, a global variable, ...).
