builtins.c (get_pointer_alignment): Honor DECL_ALIGN on a FUNCTION_DECL.
* builtins.c (get_pointer_alignment): Honor DECL_ALIGN on a
FUNCTION_DECL.
* tree.c (build_decl_stat): Move code from here...
(make_node_stat): ... to here. Don't uselessly clear DECL_USER_ALIGN.
(expr_align): Honor DECL_ALIGN on a FUNCTION_DECL. Add comment
about using DECL_ALIGN of LABEL_DECL and CONST_DECL.
* tree.h (DECL_USER_ALIGN): Fix misplaced comment.
* varasm.c (assemble_start_function): Use DECL_ALIGN instead of
FUNCTION_BOUNDARY.
