================
Comment at: clang/lib/CodeGen/CodeGenModule.cpp:1669-1672
+    if (CodeGenOpts.StackProbeSize != 4096)
+      B.addAttribute("stack-probe-size",
+                     llvm::utostr(CodeGenOpts.StackProbeSize));
+  }
----------------
Would it be worth always setting the `stack-probe-size` attribute so that it is always correct and to avoid the risk of it going out-of-sync in case of changes to the assumed size in the backend?
