        PR 32617
        * c-common.c (c_alignof_expr): Look at DECL_ALIGN of
        FUNCTION_DECLs.
        (handle_aligned_attribute): Allow use on FUNCTION_DECLs.
        * varasm.c (assemble_start_function): Honor DECL_ALIGN
        for FUNCTION_DECLs.  Don't use align_functions_log if
        DECL_USER_ALIGN.
        * print-tree.c (print_node): Print DECL_ALIGN and DECL_USER_ALIGN
        even for FUNCTION_DECLs.
        * c-decl.c (merge_decls): Propagate DECL_ALIGN even for
        FUNCTION_DECLs.
        * tree.h (DECL_ALIGN): Update for new location of 'align'.
        (DECL_FUNCTION_CODE): Update for new location and name of
        'function_code'.
        (DECL_OFFSET_ALIGN): Update for new location of 'off_align'.
        (struct tree_decl_common): Move 'align' and 'off_align' out
        of union, ensure they're still on a 32-bit boundary.  Remove
        other fields in union 'u1'.
        (struct tree_function_decl): Add field 'function_code' replacing
        'u1.f' in tree_decl_common.
        * tree.c (build_decl_stat): Set initial value of DECL_ALIGN.
        * doc/extend.texi (Function Attributes): Add 'aligned' attribute.
        (Variable Attributes): Cross-reference 'aligned' attribute
        to Function Attributes.
        * flags.h (force_align_functions_log): Delete.
        * toplev.c (force_align_functions_log): Delete.

        * lang.c (java_init): Remove setting of force_align_functions_log.
        * class.c (add_method_1): Set DECL_ALIGN of non-static method
        to cope with ptrmemfunc_vbit_in_pfn.

        * typeck.c (cxx_alignof_expr): When alignof is used on a plain
        FUNCTION_DECL, return its alignment.
