- * When building position independent code with GCC using the -fPIC option,

- * may have symbol references that can only be resolved at load time. For a
- * variety of reasons (ELF symbol preemption, the CoW footprint of the section
- * that is modified by the loader), this results in all references to symbols
- * with external linkage to go via entries in the Global Offset Table (GOT),
- * which carries absolute addresses which need to be fixed up when the
- * executable image is loaded at an offset which is different from its link
- * time offset.
- *
- * Fortunately, there is a way to inform the compiler that such symbol
- * references will be satisfied at link time rather than at load time, by
- * giving them 'hidden' visibility.
