headline: Ada: Avoids suspicious index warnings in expanded code.
tldr: The Ada compiler now prevents spurious 'suspicious index' warnings that arose in optimized or expanded code by checking only source-native elements.

The Ada compiler was generating misleading ‘suspicious index’ warnings in code that had been optimized or expanded, where the original range constraints of variables were lost. The compiler will now only check elements originating directly from the source code, thus avoiding these erroneous warnings. This improves the clarity of compiler output by reducing false positives, allowing developers to focus on genuine issues.
