+ // --------
+ //
+ // for volatile writes we can omit generating barriers and employ a
+ // releasing store when we see a node sequence sequence with a
+ // leading MemBarRelease and a trailing MemBarVolatile as follows
+ //
+ // MemBarRelease
+ // { || } -- optional
+ // {MemBarCPUOrder}
+ // || \\
+ // || StoreX[mo_release]
+ // | \ /
+ // | MergeMem
+ // | /
+ // MemBarVolatile
+ //
+ // where
+ // || and \\ represent Ctl and Mem feeds via Proj nodes
+ // | \ and / indicate further routing of the Ctl and Mem feeds
+ //
+ // this is the graph we see for non-object stores. however, for a
+ // volatile Object store (StoreN/P) we may see other nodes below the
+ // leading membar because of the need for a GC pre- or post-write
+ // barrier.
+ //
+ // with most GC configurations we with see this simple variant which
+ // includes a post-write barrier card mark.
+ //
+ // MemBarRelease______________________________
+ // || \\ Ctl \ \\
+ // || StoreN/P[mo_release] CastP2X StoreB/CM
+ // | \ / . . . /
+ // | MergeMem
+ // | /
+ // || /
+ // MemBarVolatile
+ //
+ // i.e. the leading membar feeds Ctl to a CastP2X (which converts
+ // the object address to an int used to compute the card offset) and
+ // Ctl+Mem to a StoreB node (which does the actual card mark).
+ //
+ // n.b. a StoreCM node will only appear in this configuration when
+ // using CMS. StoreCM differs from a normal card mark write (StoreB)
+ // because it implies a requirement to order visibility of the card
+ // mark (StoreCM) relative to the object put (StoreP/N) using a
+ // StoreStore memory barrier (arguably this ought to be represented
+ // explicitly in the ideal graph but that is not how it works). This
+ // ordering is required for both non-volatile and volatile
+ // puts. Normally that means we need to translate a StoreCM using
+ // the sequence
+ //
+ // dmb ishst
+ // stlrb
+ //
+ // However, in the case of a volatile put if we can recognise this
+ // configuration and plant an stlr for the object write then we can
+ // omit the dmb and just plant an strb since visibility of the stlr
+ // is ordered before visibility of subsequent stores. StoreCM nodes
+ // also arise when using G1 or using CMS with conditional card
+ // marking. In these cases (as we shall see) we don't need to insert
+ // the dmb when translating StoreCM because there is already an
+ // intervening StoreLoad barrier between it and the StoreP/N.
+ //
+ // It is also possible to perform the card mark conditionally on it
+ // currently being unmarked in which case the volatile put graph
+ // will look slightly different
+ //
+ // MemBarRelease
+ // MemBarCPUOrder___________________________________________
+ // || \\ Ctl \ Ctl \ \\ Mem \
+ // || StoreN/P[mo_release] CastP2X If LoadB |
+ // | \ / \ |
+ // | MergeMem . . . StoreB
+ // | / /
+ // || /
+ // MemBarVolatile
+ //
+ // It is worth noting at this stage that both the above
+ // configurations can be uniquely identified by checking that the
+ // memory flow includes the following subgraph:
+ //
+ // MemBarRelease
+ // MemBarCPUOrder
+ // | \ . . .
+ // | StoreX[mo_release] . . .
+ // | /
+ // MergeMem
+ // |
+ // MemBarVolatile
+ //
+ // This is referred to as a *normal* subgraph. It can easily be
+ // detected starting from any candidate MemBarRelease,
+ // StoreX[mo_release] or MemBarVolatile.
+ //
+ // the code below uses two helper predicates, leading_to_normal and
+ // normal_to_leading to identify this configuration, 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 a normal graph
+ // may not be generated: when using G1 (which always employs a
+ // conditional card mark); and when using CMS with conditional card
+ // marking 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. Of course the extra nodes may be absent --
+ // they are only inserted for object puts. This significantly
+ // complicates the task of identifying whether a MemBarRelease,
+ // StoreX[mo_release] or MemBarVolatile forms part of a volatile put
+ // when using these GC configurations (see below).
+ //
+ // 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
+ // from a normal trailing MemBarVolatile. Resolving this first
+ // problem 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
+ // leading/trailing membar nodes: what do the non-normal node graph
+ // look like for these 2 special cases? and how can we determine the
+ // status of a MemBarRelease, StoreX[mo_release] or MemBarVolatile
+ // in both normal and non-normal cases?
+ //
+ // A CMS GC post-barrier wraps its card write (StoreCM) inside an If
+ // which selects conditonal execution based on the value loaded
+ // (LoadB) from the card. Ctl and Mem are fed to the If via an
+ // intervening StoreLoad barrier (MemBarVolatile).
+ //
+ // So, with CMS we may see a node graph which looks like this
+ //
+ // MemBarRelease
+ // MemBarCPUOrder_(leading)__________________
+ // C | M \ \\ C \
+ // | \ StoreN/P[mo_release] CastP2X
+ // | Bot \ /
+ // | MergeMem
+ // | /
+ // MemBarVolatile (card mark)
+ // C | || M |
+ // | LoadB |
+ // | | |
+ // | Cmp |\
+ // | / | \
+ // If | \
+ // | \ | \
+ // IfFalse IfTrue | \
+ // \ / \ | \
+ // \ / StoreCM |
+ // \ / | |
+ // Region . . . |
+ // | \ /
+ // | . . . \ / Bot
+ // | MergeMem
+ // | |
+ // MemBarVolatile (trailing)
+ //
+ // The first MergeMem merges the AliasIdxBot Mem slice from the
+ // leading membar and the oopptr Mem slice from the Store into the
+ // card mark membar. The trailing MergeMem merges the AliasIdxBot
+ // Mem slice from the card mark membar and the AliasIdxRaw slice
+ // from the StoreCM into the trailing membar (n.b. the latter
+ // proceeds via a Phi associated with the If region).
+ //
+ // G1 is quite a lot more complicated. The nodes inserted on behalf
+ // of G1 may comprise: a pre-write graph which adds the old value to
+ // the SATB queue; the releasing store itself; and, finally, a
+ // post-write graph which performs a card mark.
+ //
+ // The pre-write graph may be omitted, but only when the put is
+ // writing to a newly allocated (young gen) object and then only if
+ // there is a direct memory chain to the Initialize node for the
+ // object allocation. This will not happen for a volatile put since
+ // any memory chain passes through the leading membar.
+ //
+ // The pre-write graph includes a series of 3 If tests. The outermost
+ // If tests whether SATB is enabled (no else case). The next If tests
+ // whether the old value is non-NULL (no else case). The third tests
+ // whether the SATB queue index is > 0, if so updating the queue. The
+ // else case for this third If calls out to the runtime to allocate a
+ // new queue buffer.
+ //
+ // So with G1 the pre-write and releasing store subgraph looks like
+ // this (the nested Ifs are omitted).

+ // from the leading membar and the oopptr Mem slice from the Store
+ // into the card mark membar i.e. the memory flow to the card mark
+ // membar still looks like a normal graph.
+ //
+ // The trailing MergeMem merges an AliasIdxBot Mem slice with other
+ // Mem slices (from the StoreCM and other card mark queue stores).
+ // However in this case the AliasIdxBot Mem slice does not come
+ // direct from the card mark membar. It is merged through a series
+ // of Phi nodes. These are needed to merge the AliasIdxBot Mem flow
+ // from the leading membar with the Mem feed from the card mark
+ // membar. Each Phi corresponds to one of the Ifs which may skip
+ // around the card mark membar. So when the If implementing the NULL
+ // value check has been elided the total number of Phis is 2
+ // otherwise it is 3.
+ //
+ // So, the upshot is that in all cases the volatile put graph will
+ // include a *normal* memory subgraph betwen the leading membar and
+ // its child membar. When that child is not a card mark membar then
+ // it marks the end of a volatile put subgraph. If the child is a
+ // card mark membar then the normal subgraph will form part of a
+ // volatile put subgraph if and only if the child feeds an
+ // AliasIdxBot Mem feed to a trailing barrier via a MergeMem. That
+ // feed is either direct (for CMS) or via 2 or 3 Phi nodes merging
+ // the leading barrier memory flow (for G1).
+ //
