* Change FinalizerWatchdogDaemon to not hold objects liveMathieu Chartier2014-09-191-11/+22
| | | | | | | | | | | | | | Previously, waitForFinalization would hold whatever object was being finalized live for MAX_FINALIZE_NANOS even though the finalizer on this object was run much earlier. This caused a test to be flaky since it was assuming that the JNI weak global reference of a recently finalized object wouldn't be held live. Bug: 17305633 (cherry picked from commit 6ba680664fa14a547543a8c63708543ea8072680) Change-Id: Ide60db55190a3764c16e4919a7c71a113cbf3968

* | Add Reference.getReferent for reference intrinsic.Mathieu Chartier2014-09-091-1/+13
|/ | | | | | | | | Reference intrinsic was incorrectly inlining PhantomReference.get(). We get around this by adding a layer of indirection. Reference.get() now calls getReferent() which is intrinsified and inlined. Bug: 17429865 Change-Id: I39803506c7bd800500ca3632a6cdf1077e382bff
* Add handling for hashed uninflated object.Mathieu Chartier2014-09-081-0/+6
| | | | | | | | | | | | | | | | | This is an Optimization to reduce how often we call System.identityHashCode. If the lockword is set to the hash code state then we simply return this value. Otherwise, we use System.identityHashCode. Maps launch exclusive time spent in System.identityHashCode: Before: 4.5% After: 2.4% Bug: 16828525 (cherry picked from commit 6917aebf2eb26c2b003a72d09c1c5bb6310160b0) Change-Id: I0ccad53cb5f8f4f27fe11725a91ab45a117452a3

| * Clarify the String.compareTo contract and add tests.Elliott Hughes2014-06-261-304/+148
| | | | | | | | | | | | | | | | | | | | | | Our use of vague terms like "negative" and "positive" led VM engineers to assume they had more leeway than they actually do. While we're here, let's fix all the ambiguous use of 'character' and add a warning and link to Collator anywhere the non-standard (and non-locale-specific) case folding is used.

* | libcore: Clean up Enum.compareTo(E)Valter Strods2014-06-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | As E extends Enum<E>, it is safe to cast the comparable object to Enum<?> as it should not throw any exceptions. When it is cast, the ordinal value can be accessed directly. Doing so would be preferred as either both the variables this.ordinal and o.ordinal should be used or the methods this.ordinal() and o.ordinal() should be used without mixing them together.

* Add finalizer references in native code.Mathieu Chartier2014-05-011-3/+0
| | | | | | | | | | | Finalizers are now added from native code in the allocation code path. This is an optimization since some of the entrypoints aren't used for finalizable objects and therefore we can eliminate the check. Bug: 14078487 Change-Id: I7edba4c884abec23678e59eb7480abc344f1ffa8

| | | | | | | | | | | | | | | Add isDexOptNeededInternal() to the DexFile class. This is like isDexOptNeeded() except takes additional arguments that are used to determine whether a profile has changed of not. The isDexOptNeeded() method is part of the exported API and cannot be changed. The new method is not part of the API. Also add additional argument to the registerAppInfo() methods (the package name). This is used to determine the profile filename. Bug: 12877748 Change-Id: If862cc5d20fae4b9d46c488f401cda6d433b4a57
