+// This was copied from corefx\src\System.Numerics.Vectors\tests\Vector3Tests.cs.
+// It exposed a bug in morph, in which a SIMD field was being morphed in
+// a MACK_Ind context, even though it was under a GT_IND(G_ADDR()).
+// This was corefx issue #15713, and was "fixed" with coreclr PR # 9496,
+// and a new issue, #9518, has been filed to track the underlying unexpected
+// MACK_Ind context, which causes us to mark the Vector3 local as do-not-enregister.
