The Ada compiler now rejects pragma CPU and pragma Priority when they duplicate corresponding aspects that are already specified for a given subprogram. Previously, the pragmas were silently ignored, potentially leading to confusion. The change modifies sem_ch13.adb to record aspect CPU and Priority applied to a subprogram as a representation item during aspect specification analysis.
