Hi,

tree_inlinable_function_p issues the -Winline warning only if

  /* We only warn for functions declared `inline' by the user.  */
  do_warning = (warn_inline
		&& DECL_DECLARED_INLINE_P (fn)
		&& !DECL_NO_INLINE_WARNING_P (fn)
		&& !DECL_IN_SYSTEM_HEADER (fn));

is true, so in particular only if DECL_NO_INLINE_WARNING_P is not set.  Now 
expand_call_inline also issues the -Winline warning

      else if (warn_inline && DECL_DECLARED_INLINE_P (fn)
	       && !DECL_IN_SYSTEM_HEADER (fn)
	       && reason != CIF_UNSPECIFIED
	       && !lookup_attribute ("noinline", DECL_ATTRIBUTES (fn))
	       /* Do not warn about not inlined recursive calls.  */
	       && !cgraph_edge_recursive_p (cg_edge)
	       /* Avoid warnings during early inline pass. */
	       && cgraph_global_info_ready)

but disregards the DECL_NO_INLINE_WARNING_P flag.

Tested on i586-suse-linux, OK for the mainline?

	* tree-inline.c (expand_call_inline): Do not issue a -Winline warning
	if DECL_NO_INLINE_WARNING_P is set on the function.
