+++ SVE CodeGen Warnings ++
+
+When the WARN check lines fail in the SVE codegen tests it most likely means you
+have introduced a warning due to:
+1. Adding an invalid call to VectorType::getNumElements() or EVT::getVectorNumElements()
+   when the type is a scalable vector.
+2. Relying upon an implicit cast conversion from TypeSize to uint64_t.
+
+For generic code, please modify your code to work with ElementCount and TypeSize directly.
+For target-specific code that only deals with fixed-width vectors, use the fixed-size interfaces.
+Please refer to the code where those functions live for more details.
