David Grove added a comment -

I checked half a dozen of the failing prototype test cases on ppc64-aix. They all had the appended error (this one is from _213_javac).

Fatal error: ArrayIndexOutOfBoundsException within uninterruptible region.
Died in GC:
Exiting virtual machine due to uninterruptibility violation.

Attempting to dump the stack of all other live threads
This is somewhat risky since if the thread is running we're going to be quite confused

David Grove added a comment - I checked half a dozen of the failing prototype test cases on ppc64-aix. They all had the appended error (this one is from _213_javac). Fatal error: ArrayIndexOutOfBoundsException within uninterruptible region. Died in GC: Exiting virtual machine due to uninterruptibility violation. – Stack – at [0x00000000400198c0] Lorg/jikesrvm/VM; sysFail(Ljava/lang/String;)V at line 2027 at [0x00000000400198f0] Lorg/jikesrvm/runtime/VM_Runtime;

ok, maybe I'm missing something, but I see no way for the appened code to work with 64 bit addresses. hashAddress needs to do something else in 64bit mode I believe.

From org.mmtk.utility.heap.Map:

/**

  • Hash an address to a chunk (this is simply done via bit shifting)
    *
  • @param address The address to be hashed
  • @return The chunk number that this address hashes into
    */
    @Inline
    private static int hashAddress(Address address) { return address.toWord().rshl(Space.LOG_BYTES_IN_CHUNK).toInt(); }

/**

  • Return the space descriptor for the space in which this object
  • resides.
    *
  • @param object The object in question
  • @return The space descriptor for the space in which the object
  • resides
    */
    @Inline
    public static int getDescriptorForAddress(Address object) { if (VM.VERIFY_ASSERTIONS) VM.assertions._assert(!object.isZero()); int index = hashAddress(object); return descriptorMap[index]; }

Yeah, that looks pretty embarrassing. I'm just about to get on a plane, but I'll take a look at it RSN.

Sigh. Pushing ppc64 problems off to 2.9.3; don't think we're going to be able to nail these in 2.9.2 time frame.

This particular problem (hashAddress not working on 64 bits) was fixed last fall. There are still issues with SPECjvm98 on ppc64, but we're dealing with those under separate items.
