Browse source 
2007-04-23  Kyle Galloway  <kgallowa@redhat.com>

	* include/java-interp.h (_Jv_InterpFrame): Add pointer to the
	interpreter PC.
	(<init>): Add a pointer to the interpreter PC as a parameter with
	default value NULL.
	(get_pc): New method.
	* interpret-run.cc: If debugging, pass a pointer to the PC when
	creating the stack frame.
	* jvmti.cc (_Jv_JVMTI_GetStackTrace): Call _Jv_InterpFrame::get_pc
	to get the PC.
