17 2019-07-22 Ed Schonberg <schonberg@adacore.com>
19 * exp_ch4.adb (Expand_N_In): Do not suggest the use of attribute
20 'Valid as a replacement for a range check on a discrete type
21 when the bounds of the range are given by type conversions,

87 libgnat/s-vallli.ads, libgnat/s-valllu.ads,
88 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
89 libgnat/s-valwch.ads: Change categorization of packages that
90 implement attribute 'Value from Pure to Preelaborate, to prevent
91 undesirable optimizations when the evaluation of the attribute
92 raises Constraint_Error, but subsequent use of the result of

112 the worst case all the literals of the enumeration type would be
113 single letter literals and the Table built by the frontend would
114 have as many components as the length of the names string. As a
115 result of this enhancement, the internal tables declared using
116 Index_Table have a length closer to the real needs, thus
117 avoiding the declaration of large arrays on 32-bit CCG targets.
