21 At run-time, TLS variables are allocated on a module-by-module basis, where a module is a shared
44 Each thread has a "Dynamic Thread Vector" (DTV) with a pointer to each module's TLS block (or NULL
45 if it hasn't been allocated yet). If the executable has a TLS segment, then it will always be module
66 A TLS variable may be in a different module than the reference.

100 `R_TLS_DTPMOD` is a dynamic relocation to the index of the module containing `tls_var`, and
101 `R_TLS_DTPOFF` is a dynamic relocation to the offset of `tls_var` within its module's `PT_TLS`
104 `__tls_get_addr` looks up `TlsIndex::module`'s entry in the DTV and adds `TlsIndex::offset` to the
105 module's TLS block. Before it can do this, it ensures that the module's TLS block is allocated. A
