[PATCH] D49473: [MSan] pull insertShadowCheck() into getShadowOriginPtr(). NFC

Could you simply pass the pointer shadow value as an argument to the runtime call in the kernel, and keep userspace instrumentation as it is?



================
Comment at: lib/Transforms/Instrumentation/MemorySanitizer.cpp:1155
+    if (!InsPoint)
+      InsPoint = &*IRB.GetInsertPoint();
+
----------------
It's better to take a step back, add instrumentation, then take a step forward.
Must handle the start of the basic block separately.
