...t is used for checking other accesses. However, negative offsets are sometimes used for thread-local accesses, which are treated as very large unsigned effective addresses. Checking them would require them to first be added to the base of the thread-local storage segment. Developers can use the -mseparate-stack-seg flag to enable instrumentation of functions that have the SafeStack attribute [4, 6]. That flag also causes the runtime library to be linked [5]. Due to BND0 being treated as per-thread state, the runtime library picks an initial BND0 upper bound when the program starts that is arbitrar...
