-- The purpose of this flag is to implement the requirement stated
-- in (RM 13.9.1(9-11)) which require that the use of possibly invalid
-- values may not cause programs to become erroneous. See the function
--- Exp_Util.Expr_Known_Valid for further details. Note that the setting
+-- Checks.Expr_Known_Valid for further details. Note that the setting
-- is conservative, in the sense that if the flag is set, it must be
-- right. If the flag is not set, nothing is known about the validity.
