================
Comment at: llvm/lib/Transforms/Utils/SimplifyCFG.cpp:5512-5525
+  // If not in x86 or aarch64 mode, do not generate a relative lookup table.
+  Triple TargetTriple(M.getTargetTriple());
+  if (!(TargetTriple.getArch() == Triple::x86_64 ||
+        TargetTriple.getArch() == Triple::aarch64))
+    return false;
+
+  // If not tiny or small code model, do not generate a relative lookup table.
----------------
This should be some TLI/TTI hook.
