- // The embodiment of the adaptive LL(*), ALL(*), parsing strategy.
- //
- // <p>
- // The basic complexity of the adaptive strategy makes it harder to understand.
- // We begin with ATN simulation to build paths in a DFA. Subsequent prediction
- // requests go through the DFA first. If they reach a state without an edge for
- // the current symbol, the algorithm fails over to the ATN simulation to
- // complete the DFA path for the current input (until it finds a conflict state
- // or uniquely predicting state).</p>
- //
- // <p>
- // All of that is done without using the outer context because we want to create
- // a DFA that is not dependent upon the rule invocation stack when we do a
- // prediction. One DFA works in all contexts. We avoid using context not
- // necessarily because it's slower, although it can be, but because of the DFA
- // caching problem. The closure routine only considers the rule invocation stack
- // created during prediction beginning in the decision rule. For example, if
- // prediction occurs without invoking another rule's ATN, there are no context
- // stacks in the configurations. When lack of context leads to a conflict, we
- // don't know if it's an ambiguity or a weakness in the strong LL(*) parsing
- // strategy (versus full LL(*)).</p>
- //
- // <p>
- // When SLL yields a configuration set with conflict, we rewind the input and
- // retry the ATN simulation, this time using full outer context without adding
- // to the DFA. Configuration context stacks will be the full invocation stacks
- // from the start rule. If we get a conflict using full context, then we can
- // definitively say we have a true ambiguity for that input sequence. If we
- // don't get a conflict, it implies that the decision is sensitive to the outer
- // context. (It is not context-sensitive in the sense of context-sensitive
- // grammars.)</p>
- //
- // <p>
- // The next time we reach this DFA state with an SLL conflict, through DFA
- // simulation, we will again retry the ATN simulation using full context mode.
- // This is slow because we can't save the results and have to "interpret" the
- // ATN each time we get that input.</p>
- //
- // <p>
- // <strong>CACHING FULL CONTEXT PREDICTIONS</strong></p>
- //
- // <p>
- // We could cache results from full context to predicted alternative easily and
- // that saves a lot of time but doesn't work in presence of predicates. The set
- // of visible predicates from the ATN start state changes depending on the
- // context, because closure can fall off the end of a rule. I tried to cache
- // tuples (stack context, semantic context, predicted alt) but it was slower
- // than interpreting and much more complicated. Also required a huge amount of
- // memory. The goal is not to create the world's fastest parser anyway. I'd like
- // to keep this algorithm simple. By launching multiple threads, we can improve
- // the speed of parsing across a large number of files.</p>
- //
- // <p>
- // There is no strict ordering between the amount of input used by SLL vs LL,
- // which makes it really hard to build a cache for full context. Let's say that
- // we have input A B C that leads to an SLL conflict with full context X. That
- // implies that using X we might only use A B but we could also use A B C D to
- // resolve conflict. Input A B C D could predict alternative 1 in one position
- // in the input and A B C E could predict alternative 2 in another position in
- // input. The conflicting SLL configurations could still be non-unique in the
- // full context prediction, which would lead us to requiring more input than the
- // original A B C. To make a prediction cache work, we have to track the exact
- // input used during the previous prediction. That amounts to a cache that maps
- // X to a specific DFA for that context.</p>
- //
- // <p>
- // Something should be done for left-recursive expression predictions. They are
- // likely LL(1) + pred eval. Easier to do the whole SLL unless error and retry
- // with full LL thing Sam does.</p>
- //
- // <p>
- // <strong>AVOIDING FULL CONTEXT PREDICTION</strong></p>
- //
- // <p>
- // We avoid doing full context retry when the outer context is empty, we did not
- // dip into the outer context by falling off the end of the decision state rule,
- // or when we force SLL mode.</p>
- //
- // <p>
- // As an example of the not dip into outer context case, consider as super
- // constructor calls versus function calls. One grammar might look like
- // this:</p>
- //
- // <pre>
- // ctorBody
- // : '{' superCall? stat* '}'
- // ;
- // </pre>
- //
- // <p>
- // Or, you might see something like</p>
- //
- // <pre>
- // stat
- // : superCall ';'
- // | expression ';'
- // | ...
- // ;
- // </pre>
- //
- // <p>
- // In both cases I believe that no closure operations will dip into the outer
- // context. In the first case ctorBody in the worst case will stop at the '}'.
- // In the 2nd case it should stop at the ';'. Both cases should stay within the
- // entry rule and not dip into the outer context.</p>
- //
- // <p>
- // <strong>PREDICATES</strong></p>
- //
- // <p>
- // Predicates are always evaluated if present in either SLL or LL both. SLL and
- // LL simulation deals with predicates differently. SLL collects predicates as
- // it performs closure operations like ANTLR v3 did. It delays predicate
- // evaluation until it reaches and accept state. This allows us to cache the SLL
- // ATN simulation whereas, if we had evaluated predicates on-the-fly during
- // closure, the DFA state configuration sets would be different and we couldn't
- // build up a suitable DFA.</p>
- //
- // <p>
- // When building a DFA accept state during ATN simulation, we evaluate any
- // predicates and return the sole semantically valid alternative. If there is
- // more than 1 alternative, we report an ambiguity. If there are 0 alternatives,
- // we throw an exception. Alternatives without predicates act like they have
- // true predicates. The simple way to think about it is to strip away all
- // alternatives with false predicates and choose the minimum alternative that
- // remains.</p>
- //
- // <p>
- // When we start in the DFA and reach an accept state that's predicated, we test
- // those and return the minimum semantically viable alternative. If no
- // alternatives are viable, we throw an exception.</p>
- //
- // <p>
- // During full LL ATN simulation, closure always evaluates predicates and
- // on-the-fly. This is crucial to reducing the configuration set size during
- // closure. It hits a landmine when parsing with the Java grammar, for example,
- // without this on-the-fly evaluation.</p>
- //
- // <p>
- // <strong>SHARING DFA</strong></p>
- //
- // <p>
- // All instances of the same parser share the same decision DFAs through a
- // static field. Each instance gets its own ATN simulator but they share the
- // same {@link //decisionToDFA} field. They also share a
- // {@link PredictionContextCache} object that makes sure that all
- // {@link PredictionContext} objects are shared among the DFA states. This makes
- // a big size difference.</p>
- //
- // <p>
- // <strong>THREAD SAFETY</strong></p>
- //
- // <p>
- // The {@link ParserATNSimulator} locks on the {@link //decisionToDFA} field when
- // it adds a new DFA object to that array. {@link //addDFAEdge}
- // locks on the DFA for the current decision when setting the
- // {@link DFAState//edges} field. {@link //addDFAState} locks on
- // the DFA for the current decision when looking up a DFA state to see if it
- // already exists. We must make sure that all requests to add DFA states that
- // are equivalent result in the same shared DFA object. This is because lots of
- // threads will be trying to update the DFA at once. The
- // {@link //addDFAState} method also locks inside the DFA lock
- // but this time on the shared context cache when it rebuilds the
- // configurations' {@link PredictionContext} objects using cached
- // subgraphs/nodes. No other locking occurs, even during DFA simulation. This is
- // safe as long as we can guarantee that all threads referencing
- // {@code s.edge[t]} get the same physical target {@link DFAState}, or
- // {@code null}. Once into the DFA, the DFA simulation does not reference the

- // targets. The DFA simulator will either find {@link DFAState//edges} to be
- // {@code null}, to be non-{@code null} and {@code dfa.edges[t]} null, or
- // {@code dfa.edges[t]} to be non-null. The
- // {@link //addDFAEdge} method could be racing to set the field
- // but in either case the DFA simulator works; if {@code null}, and requests ATN

- // <strong>Starting with SLL then failing to combined SLL/LL (Two-Stage
- // Parsing)</strong></p>
- //
- // <p>
- // Sam pointed out that if SLL does not give a syntax error, then there is no
- // point in doing full LL, which is slower. We only have to try LL if we get a
- // syntax error. For maximum speed, Sam starts the parser set to pure SLL
- // mode with the {@link BailErrorStrategy}:</p>
- //
- // <pre>
- // parser.{@link Parser//getInterpreter() getInterpreter()}.{@link //setPredictionMode setPredictionMode}{@code (}{@link PredictionMode//SLL}{@code )};
- // parser.{@link Parser//setErrorHandler setErrorHandler}(new {@link BailErrorStrategy}());
- // </pre>
- //
- // <p>
- // If it does not get a syntax error, then we're done. If it does get a syntax
- // error, we need to retry with the combined SLL/LL strategy.</p>
- //
- // <p>
- // The reason this works is as follows. If there are no SLL conflicts, then the
- // grammar is SLL (at least for that input set). If there is an SLL conflict,
- // the full LL analysis must yield a set of viable alternatives which is a
- // subset of the alternatives reported by SLL. If the LL set is a singleton,
- // then the grammar is LL but not SLL. If the LL set is the same size as the SLL
- // set, the decision is SLL. If the LL set has size > 1, then that decision
- // is truly ambiguous on the current input. If the LL set is smaller, then the
- // SLL conflict resolution might choose an alternative that the full LL would
- // rule out as a possibility based upon better context information. If that's
- // the case, then the SLL parse will definitely get an error because the full LL
- // analysis says it's not viable. If SLL conflict resolution chooses an
- // alternative within the LL set, them both SLL and LL would choose the same
- // alternative because they both choose the minimum of multiple conflicting
- // alternatives.</p>
- //
- // <p>
- // Let's say we have a set of SLL conflicting alternatives {@code {1, 2, 3}} and
- // a smaller LL set called <em>s</em>. If <em>s</em> is {@code {2, 3}}, then SLL
- // parsing will get an error because SLL will pursue alternative 1. If
- // <em>s</em> is {@code {1, 2}} or {@code {1, 3}} then both SLL and LL will
- // choose the same alternative because alternative one is the minimum of either
- // set. If <em>s</em> is {@code {2}} or {@code {3}} then SLL will get a syntax
- // error. If <em>s</em> is {@code {1}} then SLL will succeed.</p>
- //
- // <p>
- // Of course, if the input is invalid, then we will get an error for sure in
- // both SLL and LL parsing. Erroneous input will therefore require 2 passes over
- // the input.</p>

- // the following cases.</p>
- //
- // <ul>
- // <li>The usual SLL+LL fallback upon SLL conflict</li>
- // <li>Pure SLL without LL fallback</li>
- // </ul>
- //
- // <p><strong>COMBINED SLL+LL PARSING</strong></p>
- //
- // <p>When LL-fallback is enabled upon SLL conflict, correct predictions are
- // ensured regardless of how the termination condition is computed by this
- // method. Due to the substantially higher cost of LL prediction, the
- // prediction should only fall back to LL when the additional lookahead
- // cannot lead to a unique SLL prediction.</p>
- //
- // <p>Assuming combined SLL+LL parsing, an SLL configuration set with only
- // conflicting subsets should fall back to full LL, even if the
- // configuration sets don't resolve to the same alternative (e.g.
- // {@code {1,2}} and {@code {3,4}}. If there is at least one non-conflicting
- // configuration, SLL could continue with the hopes that more lookahead will
- // resolve via one of those non-conflicting configurations.</p>
- //
- // <p>Here's the prediction termination rule them: SLL (for SLL+LL parsing)
- // stops when it sees only conflicting configuration subsets. In contrast,
- // full LL keeps going when there is uncertainty.</p>
- //
- // <p><strong>HEURISTIC</strong></p>
- //
- // <p>As a heuristic, we stop prediction when we see any conflicting subset
- // unless we see a state that only has one alternative associated with it.
- // The single-alt-state thing lets prediction continue upon rules like
- // (otherwise, it would admit defeat too soon):</p>
- //
- // <p>{@code [12|1|[], 6|2|[], 12|2|[]]. s : (ID | ID ID?) ';' ;}</p>
- //
- // <p>When the ATN simulation reaches the state before {@code ';'}, it has a
- // DFA state that looks like: {@code [12|1|[], 6|2|[], 12|2|[]]}. Naturally
- // {@code 12|1|[]} and {@code 12|2|[]} conflict, but we cannot stop
- // processing this node because alternative to has another way to continue,
- // via {@code [6|2|[]]}.</p>
- //
- // <p>It also let's us continue for this rule:</p>
- //
- // <p>{@code [1|1|[], 1|2|[], 8|3|[]] a : A | A | A B ;}</p>
- //
- // <p>After matching input A, we reach the stop state for rule A, state 1.
- // State 8 is the state right before B. Clearly alternatives 1 and 2
- // conflict and no amount of further lookahead will separate the two.
- // However, alternative 3 will be able to continue and so we do not stop
- // working on this state. In the previous example, we're concerned with
- // states associated with the conflicting alternatives. Here alt 3 is not
- // associated with the conflicting configs, but since we can continue
- // looking for input reasonably, don't declare the state done.</p>
- //
- // <p><strong>PURE SLL PARSING</strong></p>
- //
- // <p>To handle pure SLL parsing, all we have to do is make sure that we
- // combine stack contexts for configurations that differ only by semantic
- // predicate. From there, we can do the usual SLL termination heuristic.</p>
- //
- // <p><strong>PREDICATES IN SLL+LL PARSING</strong></p>
- //
- // <p>SLL decisions don't evaluate predicates until after they reach DFA stop
- // states because they need to create the DFA cache that works in all
- // semantic situations. In contrast, full LL evaluates predicates collected
- // during start state computation so it can ignore predicates thereafter.
- // This means that SLL termination detection can totally ignore semantic
- // predicates.</p>
- //
- // <p>Implementation-wise, {@link ATNConfigSet} combines stack contexts but not
- // semantic predicate contexts so we might see two configurations like the
- // following.</p>
- //
- // <p>{@code (s, 1, x, {}), (s, 1, x', {p})}</p>
- //
- // <p>Before testing these configurations against others, we have to merge
- // {@code x} and {@code x'} (without modifying the existing configurations).
- // For example, we test {@code (x+x')==x''} when looking for conflicts in
- // the following configurations.</p>
- //
- // <p>{@code (s, 1, x, {}), (s, 1, x', {p}), (s, 2, x'', {})}</p>
- //
- // <p>If the configuration set has predicates (as indicated by
- // {@link ATNConfigSet//hasSemanticContext}), this algorithm makes a copy of
- // the configurations to strip out all of the predicates so that a standard

- // means we can stop since no more lookahead will change that fact. On the
- // other hand, there might be multiple conflicts that resolve to different
- // minimums. That means we need more look ahead to decide which of those
- // alternatives we should predict.</p>
- //
- // <p>The basic idea is to split the set of configurations {@code C}, into
- // conflicting subsets {@code (s, _, ctx, _)} and singleton subsets with
- // non-conflicting configurations. Two configurations conflict if they have
- // identical {@link ATNConfig//state} and {@link ATNConfig//context} values
- // but different {@link ATNConfig//alt} value, e.g. {@code (s, i, ctx, _)}
- // and {@code (s, j, ctx, _)} for {@code i!=j}.</p>
- //
- // <p>Reduce these configuration subsets to the set of possible alternatives.
- // You can compute the alternative subsets in one pass as follows:</p>
- //
- // <p>{@code A_s,ctx = {i | (s, i, ctx, _)}} for each configuration in
- // {@code C} holding {@code s} and {@code ctx} fixed.</p>
- //
- // <p>Or in pseudo-code, for each configuration {@code c} in {@code C}:</p>
- //
- // <pre>
- // map[c] U= c.{@link ATNConfig//alt alt} // map hash/equals uses s and x, not
- // alt and not pred
- // </pre>
- //
- // <p>The values in {@code map} are the set of {@code A_s,ctx} sets.</p>
- //
- // <p>If {@code |A_s,ctx|=1} then there is no conflict associated with
- // {@code s} and {@code ctx}.</p>
- //
- // <p>Reduce the subsets to singletons by choosing a minimum of each subset. If
- // the union of these alternative subsets is a singleton, then no amount of
- // more lookahead will help us. We will always pick that alternative. If,
- // however, there is more than one alternative, then we are uncertain which
- // alternative to predict and must continue looking for resolution. We may
- // or may not discover an ambiguity in the future, even if there are no
- // conflicting subsets this round.</p>
- //
- // <p>The biggest sin is to terminate early because it means we've made a
- // decision but were uncertain as to the eventual outcome. We haven't used
- // enough lookahead. On the other hand, announcing a conflict too late is no
- // big deal; you will still have the conflict. It's just inefficient. It
- // might even look until the end of file.</p>
- //
- // <p>No special consideration for semantic predicates is required because
- // predicates are evaluated on-the-fly for full LL prediction, ensuring that
- // no configuration contains a semantic context during the termination
- // check.</p>
- //
- // <p><strong>CONFLICTING CONFIGS</strong></p>
- //
- // <p>Two configurations {@code (s, i, x)} and {@code (s, j, x')}, conflict
- // when {@code i!=j} but {@code x=x'}. Because we merge all
- // {@code (s, i, _)} configurations together, that means that there are at
- // most {@code n} configurations associated with state {@code s} for
- // {@code n} possible alternatives in the decision. The merged stacks

- // resynchronization set of the current rule.
- //
- // <p>If the sub rule is optional ({@code (...)?}, {@code (...)*}, or block
- // with an empty alternative), then the expected set includes what follows
- // the subrule.</p>
- //
- // <p>During loop iteration, it consumes until it sees a token that can start a
- // sub rule or what follows loop. Yes, that is pretty aggressive. We opt to
- // stay in the loop as long as possible.</p>
- //
- // <p><strong>ORIGINS</strong></p>

- // Compute the error recovery set for the current rule. During

- // computing FIRST of what follows the rule reference in the
- // enclosing rule. See LinearApproximator.FIRST().
- // This local follow set only includes tokens
- // from within the rule; i.e., the FIRST computation done by
- // ANTLR stops at the end of a rule.
- //
- // EXAMPLE
- //
- // When you find a "no viable alt exception", the input is not
- // consistent with any of the alternatives for rule r. The best
- // thing to do is to consume tokens until you see something that
- // can legally follow a call to r//or* any rule that called r.
- // You don't want the exact set of viable next tokens because the
- // input might just be missing a token--you might consume the
- // rest of the input looking for one of the missing tokens.
- //
- // Consider grammar:
- //
- // a : '[' b ']'
- // | '(' b ')'
- // ;
- // b : c '^' INT ;
- // c : ID
- // | INT
- // ;
- //
- // At each rule invocation, the set of tokens that could follow
- // that rule is pushed on a stack. Here are the various
- // context-sensitive follow sets:
- //
- // FOLLOW(b1_in_a) = FIRST(']') = ']'
- // FOLLOW(b2_in_a) = FIRST(')') = ')'
- // FOLLOW(c_in_b) = FIRST('^') = '^'
- //
- // Upon erroneous input "[]", the call chain is
- //
- // a -> b -> c
- //
- // and, hence, the follow context stack is:
- //
- // depth follow set start of rule execution
- // 0 <EOF> a (from main())
- // 1 ']' b
- // 2 '^' c
- //
- // Notice that ')' is not included, because b would have to have
- // been called from a different context in rule a for ')' to be
- // included.
- //
- // For error recovery, we cannot consider FOLLOW(c)
- // (context-sensitive or otherwise). We need the combined set of
- // all context-sensitive FOLLOW sets--the set of all tokens that
- // could follow any reference in the call chain. We need to
- // resync to one of those tokens. Note that FOLLOW(c)='^' and if
- // we resync'd to that token, we'd consume until EOF. We need to
- // sync to context-sensitive FOLLOWs for a, b, and c: {']','^'}.
- // In this case, for input "[]", LA(1) is ']' and in the set, so we would
- // not consume anything. After printing an error, rule c would
- // return normally. Rule b would not find the required '^' though.
- // At this point, it gets a mismatched token error and throws an
- // exception (since LA(1) is not in the viable following token
- // set). The rule exception handler tries to recover, but finds
- // the same recovery set and doesn't consume anything. Rule b
- // exits normally returning to rule a. Now it finds the ']' (and
- // with the successful match exits errorRecovery mode).
- //
- // So, you can see that the parser walks up the call chain looking
- // for the token that was a member of the recovery set.
- //
- // Errors are not generated in errorRecovery mode.
- //
- // ANTLR's error recovery mechanism is based upon original ideas:
- //
- // "Algorithms + Data Structures = Programs" by Niklaus Wirth
- //
- // and
- //
- // "A note on error recovery in recursive descent parsers":
- // http://portal.acm.org/citation.cfm?id=947902.947905
- //
- // Later, Josef Grosch had some good ideas:
- //
- // "Efficient and Comfortable Error Recovery in Recursive Descent
- // Parsers":
- // ftp://www.cocolab.com/products/cocktail/doca4.ps/ell.ps.zip
- //
- // Like Grosch I implement context-sensitive FOLLOW sets that are combined
- // at run-time upon error to avoid overhead during parsing.
