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

253 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
254 libgnat/s-valwch.ads: Change categorization of packages that
255 implement attribute 'Value from Pure to Preelaborate, to prevent
256 undesirable optimizations when the evaluation of the attribute
257 raises Constraint_Error, but subsequent use of the result of
258 this evsaluation is removed by a subsequent optimization.

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