Examples with DynamicHub com.oracle.svm.core.hub.DynamicHub used on opensource projects

Example 1 with DynamicHub

use of com.oracle.svm.core.hub.DynamicHub in project graal by oracle.

the class JavaLangSubstitutions method identityHashCode.

@Substitute
private static int identityHashCode(Object obj) {
    if (obj == null) {
        return 0;
    }
    DynamicHub hub = KnownIntrinsics.readHub(obj);
    int hashCodeOffset = hub.getHashCodeOffset();
    if (hashCodeOffset == 0) {
        throw VMError.shouldNotReachHere("identityHashCode called on illegal object");
    }
    UnsignedWord hashCodeOffsetWord = WordFactory.unsigned(hashCodeOffset);
    int hashCode = ObjectAccess.readInt(obj, hashCodeOffsetWord);
    if (hashCode != 0) {
        return hashCode;
    }
    /* On the first invocation for an object create a new hash code. */
    hashCode = IdentityHashCodeSupport.generateHashCode();
    if (!UnsafeAccess.UNSAFE.compareAndSwapInt(obj, hashCodeOffset, 0, hashCode)) {
        /* We lost the race, so there now must be a hash code installed from another thread. */
        hashCode = ObjectAccess.readInt(obj, hashCodeOffsetWord);
    }
    VMError.guarantee(hashCode != 0, "Missing identity hash code");
    return hashCode;
}
