1417 context is currently established.
1418
1419 We define a context as a snapshot of the parser stacks. We define
1420 the initial context for a lookahead as the context in which the
1421 parser initially examines that lookahead in order to select a
1422 syntactic action. Thus, if the lookahead eventually proves
1423 syntactically unacceptable (possibly in a later context reached via a
1424 series of reductions), the initial context can be used to determine
1425 the exact set of tokens that would be syntactically acceptable in the
1426 lookahead's place. Moreover, it is the context after which any
1427 further semantic actions would be erroneous because they would be
1428 determined by a syntactically unacceptable token.
1429
1430 YY_LAC_ESTABLISH should be invoked when a reduction is about to be
1431 performed in an inconsistent state (which, for the purposes of LAC,
1432 includes consistent states that don't know they're consistent because
1433 their default reductions have been disabled). Iff there is a
1434 lookahead token, it should also be invoked before reporting a syntax
1435 error. This latter case is for the sake of the debugging output.
1436
1437 For parse.lac=full, the implementation of YY_LAC_ESTABLISH is as
1438 follows. If no initial context is currently established for the
1439 current lookahead, then check if that lookahead can eventually be
1440 shifted if syntactic actions continue from the current context.
