325 /* The following macros are used for PLT bypassing within libc.so
326 (and if needed other libraries similarly).
327 First of all, you need to have the function prototyped somewhere,
332 If calls to foo within libc.so should always go to foo defined in libc.so,
333 then in include/foo.h you add:
335 libc_hidden_proto (foo)
337 line and after the foo function definition:
343 libc_hidden_def (foo)
351 libc_hidden_weak (foo)
353 Similarly for global data. If references to foo within libc.so should
354 always go to foo defined in libc.so, then in include/foo.h you add:
356 libc_hidden_proto (foo)
358 line and after foo's definition:
360 int foo = INITIAL_FOO_VALUE;
361 libc_hidden_data_def (foo)
365 int foo = INITIAL_FOO_VALUE;
366 libc_hidden_data_weak (foo)
368 If foo is normally just an alias (strong or weak) to some other function,
369 you should use the normal strong_alias first, then add libc_hidden_def
376 strong_alias (baz, foo)
377 libc_hidden_weak (foo)
379 If the function should be internal to multiple objects, say ld.so and
380 libc.so, the best way is to use:
382 #if !defined NOT_IN_libc || defined IS_IN_rtld
386 in include/foo.h and the normal macros at all function definitions
387 depending on what DSO they belong to.
389 If versioned_symbol macro is used to define foo,
390 libc_hidden_ver macro should be used, as in:
392 int __real_foo (int __bar)
396 versioned_symbol (libc, __real_foo, foo, GLIBC_2_1);
397 libc_hidden_ver (__real_foo, foo) */
399 /* uClibc specific (the above comment was copied from glibc):
400 * a. when ppc64 will be supported, we need changes to support:
401 * strong_data_alias (used by asm hidden_data_def)
402 * b. libc_hidden_proto(foo) should be added after the header having foo's prototype
403 * or after extern foo... to all source files that should use the internal version
404 * of foo within libc, even to the file defining foo itself, libc_hidden_def does
405 * not hide __GI_foo itself, although the name suggests it (hiding is done exclusively
406 * by libc_hidden_proto). The reasoning to have it after the header w/ foo's prototype is
407 * to get first the __REDIRECT from original header and then create the __GI_foo alias
408 * c. no versioning support, hidden[_data]_ver are noop
409 * d. hidden_def() in asm is _hidden_strong_alias (not strong_alias) */
