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

312 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
313 libgnat/s-valwch.ads: Change categorization of packages that
314 implement attribute 'Value from Pure to Preelaborate, to prevent
315 undesirable optimizations when the evaluation of the attribute
316 raises Constraint_Error, but subsequent use of the result of
317 this evsaluation is removed by a subsequent optimization.

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

378 * sem_ch3.adb (Convert_Bound): Subsidiary of
379 Floating_Point_Type_Declaration, to handle properly range
