URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=139354
Log:
gcc:
        * lto-tree-flags.def: Stream private_flag for
        PARM_DECL and RESULT_DECL.
        * lto-function-out.c (output_type): Use debug token
        "fields" for unions as well as records.
        * lto-function-in.c (typedef tree_ptr): New.
        Also, declared vec.h-style vector of same.
        (global_vector_enter): Added need_fixups parameter,
        and code to mark vector entry for backpatching.
        (global_vector_fixup): Implement backpatching of
        references to the replaced vector entry.  Add comments.
        Call ggc_free on the replaced node.
        (input_field_decl, input_function_decl, input_var_decl,
        input_parm_decl, input_result_decl, input_type_decl,
        input_namespace_decl, input_translation_unit_decl,
        input_binfo, input_type): Use new API for reading
        backpatchable fields.
        (input_type): Use debug token "fields" for unions
        as well as records.
        (input_tree_operand): Assert if reference is resolved
        to a backpatchable node without providing a location
        to backpatch.  Add comment.  Allow for backpatching
        of operands of TREE_VEC, TREE_LIST, and various
        expression operators.
        (input_tree): Added slot parameter, providing location
        to backpatch.  Added code to register this location
        for backpatching if needed.
        (input_type_tree): Made static.
        * lto-tree-in.h (input_tree): Added slot parameter
        to function prototype.

gcc/lto:

        * lto.c (lto_read_decls): Provide dummy argument to input_tree
        to conform to its new signature.
        * lto-symtab.c (lto_symtab_merge_decl): Do not invoke ggc_free
        on discarded node here, now called in global_vector_fixup
