92 'Valid as a replacement for a range check on a discrete type
93 when the bounds of the range are given by type conversions,
94 because in such a case there are distinct types involved and the

160 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
161 libgnat/s-valwch.ads: Change categorization of packages that
162 implement attribute 'Value from Pure to Preelaborate, to prevent
163 undesirable optimizations when the evaluation of the attribute
164 raises Constraint_Error, but subsequent use of the result of
165 this evsaluation is removed by a subsequent optimization.

183 Index_Table with range Natural'First .. Names'Length since in
184 the worst case all the literals of the enumeration type would be
185 single letter literals and the Table built by the frontend would
186 have as many components as the length of the names string. As a
187 result of this enhancement, the internal tables declared using
188 Index_Table have a length closer to the real needs, thus
189 avoiding the declaration of large arrays on 32-bit CCG targets.
