| 1 Current status and remaining issues in the IRInterpreter for HIR (September/18/09) | |
| 2 ================================================================================= | |
| 3 | |
| 4 Known Problems: | |
| 5 With InterpretInvokedMethods disabled in C1XOptions: | |
| 6 (2 fails) | |
| 7 304: jtt/jvmni/JVM_GetClassContext01.java: (0) failed with false (expected true) | |
| 8 557: jtt/reflect/Class_newInstance02.java: (0) failed with true (expected !java.lang.IllegalAccessException) | |
| 9 | |
| 10 The first problem is caused by the use of reflection in the IRInterpreter, and the calling stack is not as | |
| 11 expected by the JVM_GetClassContext01 test case. The second one is due to the private constructor of Class_newInstance01. | |
| 12 Again, we are using reflection to call the newInstance() method to create an instance of class Class_newInstance01 | |
| 13 from the IRInterpreter class, which raises an IllegalAccessException. | |
| 14 These are the only problems with all optimization levels. | |
| 15 | |
| 16 With InterpretInvokedMethods enabled in C1XOptions: | |
| 17 (7 fails) | |
| 18 245: jtt/except/Catch_StackOverflowError_03.java: (0) failed with !java.lang.InstantiationException (expected 0) | |
| 19 304: jtt/jvmni/JVM_GetClassContext01.java: (0) failed with false (expected true) | |
| 20 311: jtt/lang/Bridge_method01.java: (0) failed with unexpected com.sun.c1x.ci.CiBailout (expected 1) | |
| 21 557: jtt/reflect/Class_newInstance02.java: (0) failed with true (expected !java.lang.IllegalAccessException) | |
| 22 572: jtt/reflect/Invoke_virtual01.java: (1) failed with unexpected com.sun.c1x.ci.CiBailout (expected 55) | |
| 23 575: jtt/reflect/Reflection_getCallerClass01.java: (1) failed with com.sun.c1x.debug.IRInterpreter$Evaluator (expected jtt.reflect.Reflection_getCallerClass01$Caller1) | |
| 24 592: jtt/threads/Thread_isInterrupted04.java: (0) failed with false (expected true) | |
| 25 | |
| 26 Those are also due to reflection usage. The last problem has not been investigated. |
