2005-03-10 Bryce McKinlay <mckinlay@redhat.com> New Stack Trace infrastructure. * Makefile.am (libgcj0_convenience_la_SOURCES): Add stacktrace.cc. (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. From-SVN: r96253
