* -XX:TraceC1X=0...5 controls the native c1x tracing * -Dc1x.debug=true turns on the logging proxies and lots of log output on the java side * provide more information about types to the compiler (type hierarchy, etc) * provide exception handler tables to the compiler * add exception handlers to the nmethod * correct implementation of ExceptionObject * exception handling/unwinding entry points * modified versions of handle/unwind exception stubs using standard calling conventions * exception throwing * implicit null pointer exception, implicit div by 0 exception * arraystore/classcast/arrayindex exceptions * checkcast implementation * newarray, anewarray, multinewarray implementation * correct new instance initialization * access to java class mirrors (for ldc) * unresolved methods * class resolving - class patching (asssembly prototype copying)
