Some more: /home/pinskia/src/newtest/trunk/libjava/java/lang/ref/natReference.cc: In member function 'void java::lang::ref::Reference::create(java::lang::Object*)': /home/pinskia/src/newtest/trunk/libjava/java/lang/ref/natReference.cc:366: warning: dereferencing type-punned pointer will break strict-aliasing rules /home/pinskia/src/newtest/trunk/libjava/boehm.cc: In function 'void* _Jv_MarkArray(void*, void*, void*, void*)': /home/pinskia/src/newtest/trunk/libjava/boehm.cc:377: warning: dereferencing type-punned pointer will break strict-aliasing rules
Confirmed, I completely forgot about these. Most of them were false positives, if I remember correctly.

(_Jv_MarkObject): Don't mark the class, it is reachable via the vtable. (_Jv_MarkArray): Likewise. * java/lang/ref/natReference.cc (java::lang::ref::Reference::create): Simplify _Jv_GCRegisterDisappearingLink() call. * java/lang/Class.h (getComponentType): Use element_type. (element_type): New field declaration, as a union with "methods". * java/lang/natClassLoader.cc (_Jv_NewArrayClass): Use "element_type". * java/net/natVMNetworkInterfacePosix.cc (java::net::VMNetworkInterface::getInterfaces): Add "int" cast to avoid sign comparison warning. * include/java-interp.h (_Jv_InterpFrame): Take thread as second argument, not parent call frame. * include/x86_64-signal.h (MAKE_THROW_FRAME): Use "gregs" directly, without a cast. (restore_rt): Declare with hidden visibility, not "static". * posix.cc (_Jv_platform_initProperties): Make "tmpdir" a string constant. * jni.cc (_Jv_JNI_DestroyJavaVM): Use a union to avoid strict alias warning Modified: trunk/libjava/ChangeLog trunk/libjava/boehm.cc trunk/libjava/gnu/gcj/io/natSimpleSHSStream.cc trunk/libjava/include/java-interp.h trunk/libjava/include/x86_64-signal.h trunk/libjava/interpret.cc trunk/libjava/java/lang/Class.h trunk/libjava/java/lang/natClassLoader.cc trunk/libjava/java/lang/ref/natReference.cc trunk/libjava/java/net/natVMNetworkInterfacePosix.cc trunk/libjava/jni.cc trunk/libjava/posix.cc
Fixed.
