+#ifndef PRODUCT
+  // This is a generic constructor which is only used by pns() in debug.cpp.
+  // pns (i.e. print native stack) uses this constructor to create a starting
+  // frame for stack walking. The implementation of this constructor is platform
+  // dependent (i.e. SPARC doesn't need an 'fp' argument an will ignore it) but
+  // we want to keep the signature generic because pns() is shared code.

   // pc: Returns the pc at which this frame will continue normally.
