I guess so. Or you could define foo with C linkage:

     extern "C" {
          static inline __attribute__((always_inline))
          void foo(void){}
     };

     static inline __attribute__((always_inline,alias("foo")))
     void bar(void);

     static
     void f(void) { foo(); }
     // must have a usage to generate any code

Pure inline functions may be overloaded, how will you
decide which one to alias given only unmangled name?
