- // when using these GC configurations (see below). It adds similar
- // complexity to the task of identifying whether a MemBarRelease,
- // CompareAndSwapX or MemBarAcquire forms part of a CAS.
- //
- // In both cases the post-write subtree includes an auxiliary
- // MemBarVolatile (StoreLoad barrier) separating the object put and
- // the read of the corresponding card. This poses two additional
- // problems.
- //
- // Firstly, a card mark MemBarVolatile needs to be distinguished

- // problem is straightforward: a card mark MemBarVolatile always
- // projects a Mem feed to a StoreCM node and that is a unique marker
+ // occur when a card mark is introduced. i.e. the CPUOrder MemBar
+ // feeds the extra CastP2X, LoadB etc nodes but the above memory
+ // flow subgraph is still present.
+ //
+ // This is referred to as a *normal* CAS subgraph. It can easily be
+ // detected starting from any candidate MemBarRelease,
+ // StoreX[mo_release] or MemBarAcquire node.
+ //
+ // The code below uses two helper predicates, leading_to_trailing
+ // and trailing_to_leading to identify these normal graphs, one
+ // validating the layout starting from the top membar and searching
+ // down and the other validating the layout starting from the lower
+ // membar and searching up.
+ //
+ // There are two special case GC configurations when the simple
+ // normal graphs above may not be generated: when using G1 (which
+ // always employs a conditional card mark); and when using CMS with
+ // conditional card marking (+CondCardMark) configured. These GCs
+ // are both concurrent rather than stop-the world GCs. So they
+ // introduce extra Ctl+Mem flow into the graph between the leading
+ // and trailing membar nodes, in particular enforcing stronger
+ // memory serialisation beween the object put and the corresponding
+ // conditional card mark. CMS employs a post-write GC barrier while
+ // G1 employs both a pre- and post-write GC barrier.
+ //
+ // The post-write barrier subgraph for these configurations includes
+ // a MemBarVolatile node -- referred to as a card mark membar --
+ // which is needed to order the card write (StoreCM) operation in
+ // the barrier, the preceding StoreX (or CompareAndSwapX) and Store
+ // operations performed by GC threads i.e. a card mark membar
+ // constitutes a StoreLoad barrier hence must be translated to a dmb
+ // ish (whether or not it sits inside a volatile store sequence).
+ //
+ // Of course, the use of the dmb ish for the card mark membar also
+ // implies theat the StoreCM which follows can omit the dmb ishst
+ // instruction. The necessary visibility ordering will already be
+ // guaranteed by the dmb ish. In sum, the dmb ishst instruction only
+ // needs to be generated for as part of the StoreCM sequence with GC
+ // configuration +CMS -CondCardMark.
+ //
+ // Of course all these extra barrier nodes may well be absent --
+ // they are only inserted for object puts. Their potential presence
+ // significantly complicates the task of identifying whether a
+ // MemBarRelease, StoreX[mo_release], MemBarVolatile or
+ // MemBarAcquire forms part of a volatile put or CAS when using
+ // these GC configurations (see below) and also complicates the
+ // decision as to how to translate a MemBarVolatile and StoreCM.
+ //
+ // So, thjis means that a card mark MemBarVolatile occurring in the
+ // post-barrier graph it needs to be distinguished from a normal
+ // trailing MemBarVolatile. Resolving this is straightforward: a
+ // card mark MemBarVolatile always projects a Mem feed to a StoreCM
+ // node and that is a unique marker
//
// MemBarVolatile (card mark)
// C | \ . . .
// | StoreCM . . .
// . . .
//
- // The second problem is how the code generator is to translate the
- // card mark barrier? It always needs to be translated to a "dmb
- // ish" instruction whether or not it occurs as part of a volatile
- // put. A StoreLoad barrier is needed after the object put to ensure
- // i) visibility to GC threads of the object put and ii) visibility
- // to the mutator thread of any card clearing write by a GC
- // thread. Clearly a normal store (str) will not guarantee this
- // ordering but neither will a releasing store (stlr). The latter
- // guarantees that the object put is visible but does not guarantee
- // that writes by other threads have also been observed.

- // So, returning to the task of translating the object put and the

+/**
+ * This abstract ReentrantContextProvider helper class manages the creation,
+ * storage, and retrieval of concrete ReentrantContext instances which can be
+ * subclassed to hold cached contextual data.
+ *
+ * It supports reentrancy as every call to acquire() provides a new unique context
+ * instance that must later be returned for reuse by a call to release(ctx)
+ * (typically in a try/finally block).
+ *
+ * It has a couple of abstract implementations which store references in a queue
+ * and/or thread-local storage.
+ * The Providers can be configured to hold ReentrantContext instances in memory
+ * using hard, soft or weak references.
+ *
+ * The acquire() and release() methods are used to retrieve and return the contexts.
+ *
+ * The {@code newContext()} method remains abstract in all implementations and
+ * must be provided by the module to create a new subclass of ReentrantContext
+ * with the appropriate contextual data in it.
+ *
+ * Sample Usage:
+ * - create a subclass ReentrantContextImpl to hold the thread state:
+ *
+ * static final class ReentrantContextImpl extends ReentrantContext {
+ * // specific cached data
+ * }
+ *
+ * - create the appropriate ReentrantContextProvider:
+ *
+ * private static final ReentrantContextProvider<ReentrantContextImpl> contextProvider =
+ * new ReentrantContextProviderTL<ReentrantContextImpl>(ReentrantContextProvider.REF_WEAK)
+ * {
+ * @Override
+ * protected ReentrantContextImpl newContext() {
+ * return new ReentrantContextImpl();
+ * }
+ * };
+ * ...
+ * void someMethod() {
+ * ReentrantContextImpl ctx = contextProvider.acquire();
+ * try {
+ * // use the context
