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.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully.
