Hi Dana,

+    case _UVRSC_VFP: {
+      unw_fpreg_t value;
+      switch (representation) {
+        case _UVRSD_VFPX:
+          // TODO(ajwong): What does this mean?
+          break;

Isn't this just a VLDM/VSTM into/from D registers? Should be similar
to the other 64-bit cases, no?

The rest looks ok to me, but please wait for Nick's review before commit.
