[llvm-commits] Segmented stacks, current status.

I did only quick scan over the patches (I'm planning to review them
later), but this hunk looks really suspicious:

+    TlsReg = X86::FS;
+    TlsOffset = 0x70;
+
...
+  } else {
+    TlsReg = X86::GS;
+    TlsOffset = 0x30;

Are you sure this will work on all subtargets we support?
