	(gnu/gcj/runtime/StackTrace.lo): Removed.
	(ordinary_java_source_files): Remove obsolete files.
	(nat_source_files): Remove obsolete files. Add natVMThrowable.cc.
	* configure.host (fallback_backtrace_h): Set backtrace header
	for mingw and cygwin targets.
	* configure.ac: Make symlink for fallback backtrace headers.
	* Makefile.in, configure: Rebuilt.
	* defineclass.cc (_Jv_ClassReader::read_one_code_attribute):
	Read 'LineNumberTable' attribute.
	(_Jv_ClassReader::read_one_class_attribute): Read 'SourceFile'
	attribute.
	(_Jv_ClassReader::handleCodeAttribute): Initialize method line
	table fields.
	* exception.cc: Remove unused include.
	* interpret.cc (DIRECT_THREADED, insn_slot): Moved to java-interp.h.
	(SAVE_PC): New macro. Save current PC in the interpreter frame.
	(NULLCHECK, NULLARRAYCHECK): Use SAVE_PC.
	(_Jv_InterpMethod::compile): Translate bytecode PC values in the line
	table to direct threaded instruction values.
	(_Jv_StartOfInterpreter, _Jv_EndOfInterpreter): Removed.
	(_Jv_InterpMethod::run): No longer member function. All
	callers updated. Remove _Unwind calls. Call SAVE_PC whenever a call
	is made or where an instruction could throw.
	(_Jv_InterpMethod::get_source_line): New. Look up source line numbers
	in line_table.
	* prims.cc (catch_segv): Construct exception after MAKE_THROW_FRAME.
	(catch_fpe): Likewise.
	* stacktrace.cc: New file. Stack trace code now here.
	* gnu/gcj/runtime/MethodRef.java:
	* gnu/gcj/runtime/NameFinder.java: Mostly reimplemented. Now simply
	calls addr2line to look up PC addresses in a given binary or shared
	library.
	* gnu/gcj/runtime/StackTrace.java, gnu/gcj/runtime/natNameFinder.cc,
	gnu/gcj/runtime/natStackTrace.cc: Removed.
	* gnu/java/lang/MainThread.java (call_main): Add comment warning that
	this function name is specially recognised by the stack trace code
	and shouldn't be changed.
	* include/java-interp.h (DIRECT_THREADED, insn_slot): Moved here.
	(struct  _Jv_LineTableEntry, line_table, line_table_len): New.
	(_Jv_InterpMethod::run): Update declaration.
	(_Jv_StackTrace_): New friend. NameFinder and StackTrace no longer
	friends.
	(_Jv_InterpFrame): Renamed from _Jv_MethodChain. Add PC field.
	* include/java-stack.h: New file. Declarations for stack tracing.
	* include/jvm.h (_Jv_Frame_info): Removed.
	* java/lang/Class.h: Update friend declarations.
	* java/lang/VMClassLoader.java (getSystemClassLoader): Simplify
	exception message.
	* java/lang/VMThrowable.java (fillInStackTrace): Now native.
	(getStackTrace): Now native.
	(data): New RawDataManaged field.
	* java/lang/natClass.cc: Update includes.
	(forName): Use _Jv_StackTrace::GetCallingClass for
	calling-classloader check.
	(getClassLoader): Likewise.
	* java/lang/natRuntime.cc: Update includes.
	(_load): Use _Jv_StackTrace::GetFirstNonSystemClassLoader.
	* java/lang/natVMSecurityManager.cc: Update includes.
	(getClassContext): Use _Jv_StackTrace::GetClassContext.
	* java/lang/natVMThrowable.cc: New file. Native methods for
	VMThrowable.
	* java/lang/reflect/natArray.cc: Update includes.
	(newInstance): Use _Jv_StackTrace::GetCallingClass to implement
	accessibility check.
	* java/lang/reflect/natConstructor.cc: Update includes.
	(newInstance): Use _Jv_StackTrace::GetCallingClass to implement
	accessibility check.
	* java/lang/reflect/natField.cc: Update includes.
	(getAddr): Use _Jv_StackTrace::GetCallingClass to implement
	accessibility check.
	* java/lang/reflect/natMethod.cc: Update includes.
	(invoke): Use _Jv_StackTrace::GetCallingClass to implement
	accessibility check.
	* java/util/natResourceBundle.cc: Update includes.
	(getCallingClassLoader): Use _Jv_StackTrace::GetCallingClass.
	* java/util/logging/natLogger.cc: Update includes. Use
	_Jv_StackTrace::GetCallerInfo to get call-site info.
	* sysdep/generic/backtrace.h: Fallback backtrace code. Stub
	implementation.
	* sysdep/i386/backtrace.h: New. Fallback backtrace code. i386
	implementation.
