/* The following macros are used for PLT bypassing within libc.so
   (and if needed other libraries similarly).

   If calls to foo within libc.so should always go to foo defined in libc.so,
   then in include/foo.h you add:

   int foo(int __bar);
   libc_hidden_proto(foo)

   line and after the foo function definition:

   int foo(int __bar) {
     return __bar;
   }
   libc_hidden_def(foo)

   or

   int foo(int __bar) {
     return __bar;
   }
   libc_hidden_weak(foo)

   Similarly for global data: if references to foo within libc.so
   should always go to foo defined in libc.so, then in include/foo.h:

   extern int foo;
   libc_hidden_proto(foo)

   and after foo's definition:

   int foo = INITIAL_FOO_VALUE;
   libc_hidden_data_def(foo)

   or

   int foo = INITIAL_FOO_VALUE;
   libc_hidden_data_weak(foo)

   If foo is normally just an alias (strong or weak) to some other function,
   you should use the normal strong_alias first, then add libc_hidden_def
   or libc_hidden_weak:

   int baz(int __bar) {
     return __bar;
   }
   strong_alias(baz, foo)
   libc_hidden_weak(foo)

   If the function should be internal to multiple objects, say ld.so and
   libc.so, the best way is to use:

   #if !defined NOT_IN_libc || defined IS_IN_rtld
   hidden_proto(foo)
   #endif

   in include/foo.h and the normal macros at all function definitions
   depending on what DSO they belong to.

   If versioned_symbol macro is used to define foo,
   libc_hidden_ver macro should be used, as in:

   int __real_foo(int __bar) {
     return __bar;
   }
   versioned_symbol(libc, __real_foo, foo, GLIBC_2_1);
   libc_hidden_ver(__real_foo, foo)
 */

/* uClibc specific (the above comment was copied from glibc):
 *
 * when ppc64 will be supported, we need changes to support
 * strong_data_alias (used by asm hidden_data_def)
 *
 * no versioning support, hidden[_data]_ver are noop
 *
 * hidden_def() in asm is _hidden_strong_alias (not strong_alias)
 *
 * libc_hidden_proto(foo) should be added after declaration
 * in the header, or after extern foo... in all source files
 * (this is discouraged).
 * libc_hidden_def does not hide __GI_foo itself, although the name
 * suggests it (hiding is done exclusively by libc_hidden_proto).

FIXME! - ?
 * The reasoning to have it after the header w/ foo's prototype is
 * to get first the __REDIRECT from original header and then create
 * the __GI_foo alias

 * Hunt for references which still go through PLT (example for x86):
 * build shared lib, then disassemble it and search for <xxx@plt>:
 * $ objdump -drx libuClibc-*.so >disasm.txt
 * $ grep -F '@plt>:' disasm.txt
 *
 * In uclibc, malloc/free and related functions should be called
 * through PLT (making it possible to use alternative malloc),
 * and possibly some __pthread_xxx functions can be called through PLT
 * (why?). The rest should not use PLT.
