================
Comment at: lib/Transforms/Instrumentation/AddressSanitizer.cpp:2913
+    LocalStackBaseAlloca = IRB.CreateAlloca(LocalStackBase->getType(), nullptr,
+                                            "asan_local_stack_base");
+    IRB.restoreIP(IP);
----------------
Could this be expressed in less lines of code by creating an AllocaInst directly, without saving and restoring IRBuilder state?
