ada: Redundant validity checks
In some cases with validity checking enabled via the -gnatVa option,
the compiler generates validity checks that can (obviously) never fail.
These include validity checks for (some) static expressions, and consecutive
identical checks generated for a single read of an object.
gcc/ada/
* checks.adb (Expr_Known_Valid): Return True for a static expression.
* exp_util.adb (Adjust_Condition): No validity check needed for a
condition if it is an expression for which a validity check has
already been generated.
