* Move quick frame info to OatQuickMethodHeader.Vladimir Marko2014-05-133-45/+42
| | | | | | | | | | | | | | | Rename OatMethodHeader to OatQuickMethodHeader, move frame info from OatMethodOffsets to OatQuickMethodHeader. Retrieve the info from other places for non-quick methods (portable compiled bytecode or jni stub, generic jni, runtime, abstract and proxy). This change has a libcore/ companion CL "Remove ArtMethod's quick fields for frame size and spills." https://android-review.googlesource.com/94164 Bug: 11767815 Change-Id: I0e31a7875d76732e1ec479c86b9b5ca01203507f
* Reference::GetReferent() calls by GC should not trigger read barriers.Hiroshi Yamauchi2014-05-091-1/+3

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We now have an invariant where we never allocate finalizable objects with the Initialized or Resolved entrypoints.

We rename the CatchFinder class to QuickExceptionHandler so it's less specific to catch handler search. Finding catch handler happens in QuickExceptionHandler::FindCatch. Since the CatchBlockStackVisitor resolves exception types, it may cause thread suspension and breaks the assertion current thread can't be suspended. Therefore, we place the exception in a SirtRef (while it is detached from the current thread) and remove the thread suspension assertion. Deoptimization now happens in QuickExceptionHandler::DeoptimizeStack. It uses the new DeoptimizeStackVisitor class to create shadow frames. We also add the Thread::GetDeoptimizationException method to get the definition of the fake exception in only one place. Change-Id: I01b19fa72af64329b5c3b6c7f0c3339d2d724978

This allows it to send JDWP field access and field modification events to debugger. This completes CL https://android-review.googlesource.com/90390. We also fix the JDWP FieldOnly modifier by introducing ModBasket.fieldTypeID. We incorrectly used ModBasket.classId which is actually dedicated to ClassOnly modifier based on thread's location's class id. Finally, we now enable canWatchFieldModification and canWatchFieldAccess JDWP capabilities so a debugger can request these events to be reported.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Speeds up large object marking since large objects no longer required a lock. Changed the GCs to use the heap bitmap for marking objects which aren't in the fast path. This eliminates the need for a MarkLargeObject function. Maps before (10 GC iterations): Mean partial time: 180ms Mean sticky time: 151ms Maps after: Mean partial time: 161ms Mean sticky time: 101ms Note: the GC durations are long due to recent ergonomic changes and because the fast bulk free hasn't yet been enabled. Over 50% of the GC time is spent in RosAllocSpace::FreeList. Bug: 13571028 Change-Id: Id8f94718aeaa13052672ccbae1e8edf77d653f62

Generalizes non-transactional mode for invariant fields (which are set only once). Removes ArrayLog::VisitRoots as we never create Array logs of ObjectArray. As ObjectArray elements are set using Object::SetFieldObject, they are already recorded in the object logs: the object is the array itself and the offset corresponds to the element index in this array. And also checks we never log ObjectArray in array logs. Fixes location of thrown exception when calling native method during class initialization. Change-Id: Idbc368d3b8292b85ff40bc8a7c559e085477bf89
