Mark Johnston 19419d36cf libc: Give __thr_jtable protected visibility ... This function pointer table is overwritten by libthr when it's loaded. libc's pthread stubs are implemented by looking up an entry in this table and invoking the function pointer contained in the entry. pthread calls are fairly expensive even when libthr is not loaded: each call involves indirection through the PLT, then through the GOT to look up __thr_jtable, then the function pointer itself. We can however eliminate one level of indirection by disallowing preemption of the __thr_jtable symbol, and since the existence table is an internal implementation detail, disabling preemption is unlikely to break anything. This gives a modest improvement in some microbenchmarks which call libc's pthread stubs.
