+<p>x86 has the ability to perform loads and stores to different address spaces 
+via the x86 segment registers.  A segment override prefix byte on an instruction
+causes the instruction's memory access to go to the specified segment.  LLVM
+address space 0 is the default address space, which includes the stack, and
+any unqualified memory accesses in a program.  Address spaces 1-255 are
+currently reserved for user-defined code.  The GS-segment is represented by
+address space 256.  Other x86 segments have yet to be allocated address space
+numbers.
+
+<p>Some operating systems use the GS-segment to implement TLS, so care should be
+taken when reading and writing to address space 256 on these platforms.
