The Ada compiler now sets the Etype decoration before analysis for conditions generated for the 'Old attribute. The absence of the Etype decoration was problematic for GNATprove, a formal verification tool for Ada, as it couldn’t properly analyze the output without it. New utilities were added in sem_util.adb to fill decoration in expressions, and the Etype is now set for generated Boolean connectors in Determining_Condition and Conditional_Evaluation_Condition.
