+# This test verifies that we can read and write the value of a pseudo register
+# in unwound frames.  For the test, we choose one raw register, rbx, and one
+# pseudo register that is backed by rbx, ebx.  We have two frames (the inner one,
+# #0 and the outer one, #1) that each set a value for rbx.  We verify that we
+# can read both rbx and ebx correctly for each frame, and that when we write to
+# ebx, rbx for that frame is correctly updated.
