[PATCH] D44802: Add the ShadowCallStack pass

[Peter Collingbourne via Phabricator via llvm-commits]

pcc added inline comments.


================
Comment at: lib/Target/X86/ShadowCallStack.cpp:89
+  const unsigned OffsetReg = X86::R11;
+  assert(!MBB->isLiveIn(X86::R10) && !MBB->isLiveIn(X86::R11));
+
----------------
I think this is possible if the function takes a nest parameter -- probably best to disable the protection in that case for now.
