natClassLoader.cc (_Jv_PrepareCompiledClass): Call _Jv_PushClass.

2002-12-03  Andrew Haley  <aph@redhat.com>

        * java/lang/natClassLoader.cc (_Jv_PrepareCompiledClass): Call
	_Jv_PushClass.
        (_Jv_InitNewClassFields): Set protectionDomain and chain = NULL.
        (_Jv_PopClass): New.
        (_Jv_PushClass): New.
        * java/lang/natClass.cc (forName (jstring)): Use a StackTrace to
        discover the ClassLoader of our caller.
        (_Jv_CheckArrayStore): Don't check that a class is assignment
        compatible with Object.
        * java/lang/natVMTHrowable.cc: Delete.
        * gnu/gcj/runtime/StackTrace.java: New, partly copied from
	java.lang.VMThrowable.
        (StackTrace(), StackTrace(int)): New constructors.
        (classAt, methodAt, update, methodAtAddress): New methods.
        (map): New field.
	* java/lang/VMThrowable.java: Use StackTrace instead of
	natVMTHrowable.
	* java/lang/Class.h (getClassLoaderInternal): New.
        (class Class): Be friendly with _Jv_PopClass and _Jv_PushClass.
        Be friendly with gnu::gcj::runtime::StackTrace.
        (Object.chain): New field.
        * include/java-interp.h (class _Jv_InterpMethod): Be friendly with
        gnu::gcj::runtime::StackTrace.
        * prims.cc (_Jv_NewObjectArray): Use getClassLoaderInternal()
        instead of getClassLoader().
        * verify.cc (class _Jv_BytecodeVerifier): Likewise.
        java::lang::VMThrowable.
        * Makefile.am (core_java_source_files): Add MethodRef.java,
	StackTrace.java.
        (nat_source_files): Remove natVMThrowable.cc; add natStackTrace.cc.
        * Makefile.in: Rebuild.
