Uniquization of constants at the Tree level
* tree.h (DECL_IN_CONSTANT_POOL): New macro
(tree_decl_with_vis): Add in_constant_pool bit, move shadowed_for_var_p
bit to the end.
(tree_output_constant_def): Declare.
* gimplify.c (gimplify_init_constructor): When using block copy,
uniquize the constant constructor on the RHS.
* lto-streamer-in.c (unpack_ts_decl_with_vis_value_fields): Deal
with DECL_IN_CONSTANT_POOL flag.
* lto-streamer-out.c (pack_ts_decl_with_vis_value_fields): Likewise.
* varasm.c (make_decl_rtl): Deal with variables belonging to the
global constant pool.
(assemble_variable): Deal with symbols belonging to the tree constant
pool.
(get_constant_section): Add ALIGN parameter and simplify.
(build_constant_desc): Build a VAR_DECL and attach it to the symbol.
(assemble_constant_contents): Use the expression of the VAR_DECL.
(output_constant_def_contents): Use the alignment of the VAR_DECL.
(tree_output_constant_def): New global function.
(mark_constant): Use the expression of the VAR_DECL.
(place_block_symbol): Use the alignment of the VAR_DECL and the size
of its expression.
(output_object_block): Likewise and assemble the expression.
ada/
* gcc-interface/trans.c (gnat_gimplify_expr) <ADDR_EXPR>: Uniquize
constant constructors before taking their address.
