+/* 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

+ * The reasoning to have it after the header w/ foo's prototype is

+ * $ 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.
