This is the address of the TLS control block. The exact definition depends on the architecture. All TLS variables are at some offset from this value. > 2. runtime.g A TLS variable that holds the current goroutine, a pointer to a g struct. > 3. runtime.g0 A global variable that holds the g struct used for the initial goroutine. > 4. runtime.m0 A global variable that holds the m struct used for the initial thread. > 5. runtime.m gccgo no longer uses this. In earlier releases it was a TLS variable that holds the current thread, a pointer to an m struct. In current releases gccgo uses g->m for this.
