H A Dfsgs.rst3 Using FS and GS segments in user space applications
21 In 64-bit mode the CS/SS/DS/ES segments are ignored and the base address is
22 always 0 to provide a full 64bit address space. The FS and GS segments are
23 still functional in 64-bit mode.
25 Common FS and GS usage
28 The FS segment is commonly used to address Thread Local Storage (TLS). FS
31 thread and the compiler emits the FS: address prefix for accesses to these
32 variables. Each thread has its own FS base address so common code can be
34 instances. Applications should not use FS for other purposes when they use
35 runtimes or threading libraries which manage the per thread FS.
