+   * the {@link BailErrorStrategy} avoids wasting work on recovering from errors
+   * when the result will be ignored either way.</li>

+     * <p>If the sub rule is optional ({@code (...)?}, {@code (...)*}, or block

+     * <p>During loop iteration, it consumes until it sees a token that can start a

+     *
+     * <p><strong>ORIGINS</strong></p>
+     *
+     * <p>Previous versions of ANTLR did a poor job of their recovery within loops.

+     * out of the entire rules surrounding the loop. So, for rule</p>

+     * <pre>
+     * classDef : 'class' ID '{' member* '}'

+     *
+     * input with an extra token between members would force the parser to
+     * consume until it found the next class definition rather than the next
+     * member definition of the current class.
+     *
+     * <p>This functionality cost a little bit of effort because the parser has to
+     * compare token set at the start of the loop and at each iteration. If for
+     * some reason speed is suffering for you, you can turn off this

+     *  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.

+   *  The root node always has a null pointer and invokingState of -1.
+   *
+   *  Upon entry to parsing, the first invoked rule function creates a
+   *  context object (asubclass specialized for that rule such as
+   *  SContext) and makes it the root of a parse tree, recorded by field
+   *  Parser._ctx.
+   *
+   *  public final SContext s() throws RecognitionException {
+   *      SContext _localctx = new SContext(_ctx, getState()); <-- create new node
+   *      enterRule(_localctx, 0, RULE_s);                     <-- push it

+   *      return _localctx;
+   *  }
+   *
+   *  A subsequent rule invocation of r from the start rule s pushes a
+   *  new context object for r whose parent points at s and use invoking
+   *  state is the state with r emanating as edge label.
+   *
+   *  The invokingState fields from a context object to the root
+   *  together form a stack of rule indication states where the root
+   *  (bottom of the stack) has a -1 sentinel value. If we invoke start
+   *  symbol s then call r1, which calls r2, the  would look like
+   *  this:
+   *
+   *     SContext[-1]   <- root node (bottom of the stack)
+   *     R1Context[p]   <- p in rule s called r1
+   *     R2Context[q]   <- q in rule r1 called r2
+   *
+   *  So the top of the stack, _ctx, represents a call to the current
+   *  rule and it holds the return address from another rule that invoke
+   *  to this rule. To invoke a rule, we must always have a current context.
+   *
+   *  The parent contexts are useful for computing lookahead sets and
+   *  getting error information.
+   *
+   *  These objects are used during parsing and prediction.

+   * Useful for rewriting out a buffered input token stream after doing some
+   * augmentation or other manipulations on it.
+   *
+   * <p>
+   * You can insert stuff, replace, and delete chunks. Note that the operations
+   * are done lazily--only if you convert the buffer to a {@link String} with
+   * {@link TokenStream#getText()}. This is very efficient because you are not
+   * moving data around all the time. As the buffer of tokens is converted to
+   * strings, the {@link #getText()} method(s) scan the input token stream and
+   * check to see if there is an operation at the current index. If so, the
+   * operation is done and then normal {@link String} rendering continues on the
+   * buffer. This is like having multiple Turing machine instruction streams
+   * (programs) operating on a single input tape. :)</p>
+   *
+   * <p>
+   * This rewriter makes no modifications to the token stream. It does not ask the
+   * stream to fill itself up nor does it advance the input cursor. The token
+   * stream {@link TokenStream#index()} will return the same value before and
+   * after any {@link #getText()} call.</p>
+   *
+   * <p>
+   * The rewriter only works on tokens that you have in the buffer and ignores the
+   * current input cursor. If you are buffering tokens on-demand, calling
+   * {@link #getText()} halfway through the input will only do rewrites for those
+   * tokens in the first half of the file.</p>
+   *
+   * <p>
+   * Since the operations are done lazily at {@link #getText}-time, operations do
+   * not screw up the token index values. That is, an insert operation at token
+   * index {@code i} does not change the index values for tokens
+   * {@code i}+1..n-1.</p>
+   *
+   * <p>
+   * Because operations never actually alter the buffer, you may always get the
+   * original token stream back without undoing anything. Since the instructions
+   * are queued up, you can easily simulate transactions and roll back any changes
+   * if there is an error just by removing instructions. For example,</p>
+   *
+   * <pre>
+   * CharStream input = new ANTLRFileStream("input");
+   * TLexer lex = new TLexer(input);
+   * CommonTokenStream tokens = new CommonTokenStream(lex);
+   * T parser = new T(tokens);
+   * TokenStreamRewriter rewriter = new TokenStreamRewriter(tokens);
+   * parser.startRule();
+   * </pre>
+   *
+   * <p>
+   * Then in the rules, you can execute (assuming rewriter is visible):</p>
+   *
+   * <pre>
+   * Token t,u;
+   * ...
+   * rewriter.insertAfter(t, "text to put after t");}
+   * rewriter.insertAfter(u, "text after u");}
+   * System.out.println(rewriter.getText());
+   * </pre>
+   *
+   * <p>
+   * You can also have multiple "instruction streams" and get multiple rewrites
+   * from a single pass over the input. Just name the instruction streams and use
+   * that name again when printing the buffer. This could be useful for generating
+   * a C file and also its header file--all from the same buffer:</p>
+   *
+   * <pre>
+   * rewriter.insertAfter("pass1", t, "text to put after t");}
+   * rewriter.insertAfter("pass2", u, "text after u");}
+   * System.out.println(rewriter.getText("pass1"));
+   * System.out.println(rewriter.getText("pass2"));
+   * </pre>
+   *
+   * <p>
+   * If you don't use named rewrite streams, a "default" stream is used as the
+   * first example shows.</p>

+   * 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
+   * {@link DFA#states} map. It follows the {@link DFAState#edges} field to new
+   * 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
+   * simulation. It could also race trying to get {@code dfa.edges[t]}, but either
+   * way it will work because it's not doing a test and set operation.</p>
+   *
+   * <p>
+   * <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 &gt; 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>

+     *  during closure operations.  See antlr/antlr4#1398.
+     *
+     * The optimization is to avoid adding the loop entry config when
+     * the exit path can only lead back to the same
+     * StarLoopEntryState after popping context at the rule end state
+     * (traversing only epsilon edges, so we're still in closure, in
+     * this same rule).
+     *
+     * We need to detect any state that can reach loop entry on
+     * epsilon w/o exiting rule. We don't have to look at FOLLOW
+     * links, just ensure that all stack tops for config refer to key
+     * states in LR rule.
+     *
+     * To verify we are in the right situation we must first check
+     * closure is at a StarLoopEntryState generated during LR removal.
+     * Then we check that each stack top of context is a return state
+     * from one of these cases:
+     *
+     *   1. 'not' expr, '(' type ')' expr. The return state points at loop entry state
+     *   2. expr op expr. The return state is the block end of internal block of (...)*
+     *   3. 'between' expr 'and' expr. The return state of 2nd expr reference.
+     *      That state points at block end of internal block of (...)*.
+     *   4. expr '?' expr ':' expr. The return state points at block end,
+     *      which points at loop entry state.
+     *
+     * If any is true for each stack top, then closure does not add a
+     * config to the current config set for edge[0], the loop entry branch.
+     *
+     *  Conditions fail if any context for the current config is:
+     *
+     *   a. empty (we'd fall out of expr to do a global FOLLOW which could
+     *      even be to some weird spot in expr) or,
+     *   b. lies outside of expr or,
+     *   c. lies within expr but at a state not the BlockEndState
+     *   generated during LR removal
+     *
+     * Do we need to evaluate predicates ever in closure for this case?
+     *
+     * No. Predicates, including precedence predicates, are only
+     * evaluated when computing a DFA start state. I.e., only before
+     * the lookahead (but not parser) consumes a token.
+     *
+     * There are no epsilon edges allowed in LR rule alt blocks or in
+     * the "primary" part (ID here). If closure is in
+     * StarLoopEntryState any lookahead operation will have consumed a
+     * token as there are no epsilon-paths that lead to
+     * StarLoopEntryState. We do not have to evaluate predicates
+     * therefore if we are in the generated StarLoopEntryState of a LR
+     * rule. Note that when making a prediction starting at that
+     * decision point, decision d=2, compute-start-state performs
+     * closure starting at edges[0], edges[1] emanating from
+     * StarLoopEntryState. That means it is not performing closure on
+     * StarLoopEntryState during compute-start-state.
+     *
+     * How do we know this always gives same prediction answer?
+     *
+     * Without predicates, loop entry and exit paths are ambiguous
+     * upon remaining input +b (in, say, a+b). Either paths lead to
+     * valid parses. Closure can lead to consuming + immediately or by
+     * falling out of this call to expr back into expr and loop back
+     * again to StarLoopEntryState to match +b. In this special case,
+     * we choose the more efficient path, which is to take the bypass
+     * path.
+     *
+     * The lookahead language has not changed because closure chooses
+     * one path over the other. Both paths lead to consuming the same
+     * remaining input during a lookahead operation. If the next token
+     * is an operator, lookahead will enter the choice block with
+     * operators. If it is not, lookahead will exit expr. Same as if
+     * closure had chosen to enter the choice block immediately.
+     *
+     * Closure is examining one config (some loopentrystate, some alt,
+     * context) which means it is considering exactly one alt. Closure
+     * always copies the same alt to any derived configs.
+     *
+     * How do we know this optimization doesn't mess up precedence in
+     * our parse trees?
+     *
+     * Looking through expr from left edge of stat only has to confirm
+     * that an input, say, a+b+c; begins with any valid interpretation
+     * of an expression. The precedence actually doesn't matter when
+     * making a decision in stat seeing through expr. It is only when
+     * parsing rule expr that we must use the precedence to get the
+     * right interpretation and, hence, parse tree.

+
+     applyPrecedenceFilter is an optimization to avoid highly
+     nonlinear prediction of expressions and other left recursive
+     rules. The precedence predicates such as {3>=prec}? Are highly
+     context-sensitive in that they can only be properly evaluated
+     in the context of the proper prec argument. Without pruning,
+     these predicates are normal predicates evaluated when we reach
+     conflict state (or unique prediction). As we cannot evaluate
+     these predicates out of context, the resulting conflict leads
+     to full LL evaluation and nonlinear prediction which shows up
+     very clearly with fairly large expressions.
+
+     Example grammar:
+
+     e : e '*' e
+     | e '+' e
+     | INT
+     ;
+
+     We convert that to the following:
+
+     e[int prec]
+     :   INT
+     ( {3>=prec}? '*' e[4]
+     | {2>=prec}? '+' e[3]
+     )*
+     ;
+
+     The (..)* loop has a decision for the inner block as well as
+     an enter or exit decision, which is what concerns us here. At
+     the 1st + of input 1+2+3, the loop entry sees both predicates
+     and the loop exit also sees both predicates by falling off the
+     edge of e.  This is because we have no stack information with
+     SLL and find the follow of e, which will hit the return states
+     inside the loop after e[4] and e[3], which brings it back to
+     the enter or exit decision. In this case, we know that we
+     cannot evaluate those predicates because we have fallen off
+     the edge of the stack and will in general not know which prec
+     parameter is the right one to use in the predicate.
+
+     Because we have special information, that these are precedence
+     predicates, we can resolve them without failing over to full
+     LL despite their context sensitive nature. We make an
+     assumption that prec[-1] <= prec[0], meaning that the current
+     precedence level is greater than or equal to the precedence
+     level of recursive invocations above us in the stack. For
+     example, if predicate {3>=prec}? is true of the current prec,
+     then one option is to enter the loop to match it now. The
+     other option is to exit the loop and the left recursive rule
+     to match the current operator in rule invocation further up
+     the stack. But, we know that all of those prec are lower or
+     the same value and so we can decide to enter the loop instead
+     of matching it later. That means we can strip out the other
+     configuration for the exit branch.
+
+     So imagine we have (14,1,$,{2>=prec}?) and then
+     (14,2,$-dipsIntoOuterContext,{2>=prec}?). The optimization
+     allows us to collapse these two configurations. We know that
+     if {2>=prec}? is true for the current prec parameter, it will
+     also be true for any prec from an invoking e call, indicated
+     by dipsIntoOuterContext. As the predicates are both true, we
+     have the option to evaluate them early in the decision start
+     state. We do this by stripping both predicates and choosing to
+     enter the loop as it is consistent with the notion of operator
+     precedence. It's also how the full LL conflict resolution
+     would work.
+
+     The solution requires a different DFA start state for each
+     precedence level.
+
+     The basic filter mechanism is to remove configurations of the
+     form (p, 2, pi) if (p, 1, pi) exists for the same p and pi. In
+     other words, for the same ATN state and predicate context,
+     remove any configuration associated with an exit branch if
+     there is a configuration associated with the enter branch.
+
+     It's also the case that the filter evaluates precedence
+     predicates and resolves conflicts according to precedence
+     levels. For example, for input 1+2+3 at the first +, we see
+     prediction filtering
+
+     [(11,1,[$],{3>=prec}?), (14,1,[$],{2>=prec}?), (5,2,[$],up=1),
+     (11,2,[$],up=1), (14,2,[$],up=1)],hasSemanticContext=true,dipsIntoOuterContext
+
+     to
+
+     [(11,1,[$]), (14,1,[$]), (5,2,[$],up=1)],dipsIntoOuterContext
+
+     This filters because {3>=prec}? evals to true and collapses
+     (11,1,[$],{3>=prec}?) and (11,2,[$],up=1) since early conflict
+     resolution based upon rules of operator precedence fits with
+     our usual match first alt upon conflict.
+
+     We noticed a problem where a recursive call resets precedence
+     to 0. Sam's fix: each config has flag indicating if it has
+     returned from an expr[0] call. then just don't filter any
+     config with that flag set. flag is carried along in
+     closure(). so to avoid adding field, set bit just under sign
+     bit of dipsIntoOuterContext (SUPPRESS_PRECEDENCE_FILTER).
+     With the change you filter "unless (p, 2, pi) was reached
+     after leaving the rule stop state of the LR rule containing
+     state p, corresponding to a rule invocation with precedence
+     level 0"

+     * <p>
+     * This method computes the SLL prediction termination condition for both of

+     *
+     * <ul>

+     * <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
+     * {@link ATNConfigSet} will merge everything ignoring predicates.</p>

+     * Full LL prediction termination.
+     *
+     * <p>Can we stop looking ahead during ATN simulation or is there some
+     * uncertainty as to which alternative we will ultimately pick, after
+     * consuming more input? Even if there are partial conflicts, we might know
+     * that everything is going to resolve to the same minimum alternative. That
+     * 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
+     * complicate the comparison of configuration contexts {@code x} and
+     * {@code x'}. Sam checks to see if one is a subset of the other by calling
+     * merge and checking to see if the merged result is either {@code x} or
+     * {@code x'}. If the {@code x} associated with lowest alternative {@code i}
+     * is the superset, then {@code i} is the only possible prediction since the
+     * others resolve to {@code min(i)} as well. However, if {@code x} is
+     * associated with {@code j>i} then at least one stack configuration for
+     * {@code j} is not in conflict with alternative {@code i}. The algorithm
+     * should keep going, looking for more lookahead due to the uncertainty.</p>
+     *
+     * <p>For simplicity, I'm doing a equality check between {@code x} and
+     * {@code x'} that lets the algorithm continue to consume lookahead longer
+     * than necessary. The reason I like the equality is of course the
+     * simplicity but also because that is the test you need to detect the
+     * alternatives that are actually in conflict.</p>
+     *
+     * <p><strong>CONTINUE/STOP RULE</strong></p>
+     *
+     * <p>Continue if union of resolved alternative sets from non-conflicting and
+     * conflicting alternative subsets has more than one alternative. We are
+     * uncertain about which alternative to predict.</p>
+     *
+     * <p>The complete set of alternatives, {@code [i for (_,i,_)]}, tells us which
+     * alternatives are still in the running for the amount of input we've
+     * consumed at this point. The conflicting sets let us to strip away
+     * configurations that won't lead to more states because we resolve
+     * conflicts to the configuration with a minimum alternate for the
+     * conflicting set.</p>

+# C++ target for ANTLR 4
+
+This folder contains the C++ runtime support for ANTLR.  See [the canonical antlr4 repository](https://github.com/antlr/antlr4) for in depth detail about how to use ANTLR 4.
+
+## Authors and major contributors
+
+ANTLR 4 is the result of substantial effort of the following people:
+
+* [Terence Parr](http://www.cs.usfca.edu/~parrt/), parrt@cs.usfca.edu
+  ANTLR project lead and supreme dictator for life
+  [University of San Francisco](http://www.usfca.edu/)
+* [Sam Harwell](http://tunnelvisionlabs.com/)
+  Tool co-author, Java and C# target)
+
+The C++ target has been the work of the following people:
+
+* Dan McLaughlin, dan.mclaughlin@gmail.com (initial port, got code to compile)
+* David Sisson, dsisson@google.com (initial port, made the runtime C++ tests runnable)
+* [Mike Lischke](www.soft-gems.net), mike@lischke-online.de (brought the initial port to a working library, made most runtime tests passing)
+
+## Other contributors
+
+* Marcin Szalowicz, mszalowicz@mailplus.pl (cmake build setup)
+* Tim O'Callaghan, timo@linux.com (additional superbuild cmake pattern script)
+
+## Project Status
+
+* Building on macOS, Windows, Android and Linux
+* No errors and warnings
+* Library linking
+* Some unit tests in the macOS project, for important base classes with almost 100% code coverage.
+* All memory allocations checked
+* Simple command line demo application working on all supported platforms.
+* All runtime tests pass.
+
+### Build + Usage Notes
+
+The minimum C++ version to compile the ANTLR C++ runtime with is C++11. The supplied projects can built the runtime either as static or dynamic library, as both 32bit and 64bit arch. The macOS project contains a target for iOS and can also be built using cmake (instead of XCode).
+
+Include the antlr4-runtime.h umbrella header in your target application to get everything needed to use the library.
+
+If you are compiling with cmake, the minimum version required is cmake 2.8.
+By default, the libraries produced by the CMake build target C++11. If you want to target a different C++ standard, you can explicitly pass the standard - e.g. `-DCMAKE_CXX_STANDARD=17`.
+
+#### Compiling on Windows with Visual Studio using he Visual Studio projects
+Simply open the VS project from the runtime folder (VS 2013+) and build it.
+
+#### Compiling on Windows using cmake with Visual Studio VS2017 and later
+Use the "Open Folder" Feature from the File->Open->Folder menu to open the runtime/Cpp directory.
+It will automatically use the CMake description to open up a Visual Studio Solution.
+
+#### Compiling on macOS
+Either open the included XCode project and build that or use the cmake compilation as described for linux.
+
+#### Compiling on Android
+Try run cmake -DCMAKE_ANDROID_NDK=/folder/of/android_ndkr17_and_above -DCMAKE_SYSTEM_NAME=Android -DCMAKE_ANDROID_API=14 -DCMAKE_ANDROID_ARCH_ABI=x86 -DCMAKE_ANDROID_STL_TYPE=c++_shared -DCMAKE_ANDROID_NDK_TOOLCHAIN_VERSION=clang -DCMAKE_BUILD_TYPE=Release /folder/antlr4_src_dir -G Ninja.
+
+#### Compiling on Linux
+- cd \<antlr4-dir\>/runtime/Cpp (this is where this readme is located)
+- mkdir build && mkdir run && cd build

+If you don't want to build the demo then simply run cmake without parameters.
+There is another cmake script available in the subfolder cmake/ for those who prefer the superbuild cmake pattern.
+
+#### CMake Package support
+If the CMake variable 'ANTLR4_INSTALL' is set, CMake Packages will be build and installed during the install step.
+They expose two packages: antlr4_runtime and antlr4_generator which can be referenced to ease up the use of the
+ANTLR Generator and runtime.
+Use and Sample can be found [here](cmake/Antlr4Package.md)

+--   $ cd projectdir\r
+--\r
+-- 1. How to build project?\r
+--\r

+--\r
+-- 3. Where is the build output directory?\r
+--\r
+--   The default output directory is `./build` and you can configure the output directory.\r
+--\r
+--   $ xmake f -o outputdir\r
+--   $ xmake\r

+--\r
+--   $ xmake run [targetname]\r
+--   $ xmake run -d [targetname]\r
