New Revision: 122181

Log:
PR ada/30684
Backport from 4.2 branch:
2006-11-17 Eric Botcazou <ebotcazou@adacore.com>
* 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.
