PR ada/27936 * ada-tree.h (DECL_READONLY_ONCE_ELAB): New macro. * decl.c (elaborate_expression_1): Test the DECL_READONLY_ONCE_ELAB flag in addition to TREE_READONLY to assert the constantness of variables for elaboration purposes. * trans.c (add_decl_expr): Do not dynamically elaborate padded objects if the initializer takes into account the padding. Set DECL_READONLY_ONCE_ELAB flag on variables originally TREE_READONLY but whose elaboration cannot be performed statically. From-SVN: r118940
