1328 | We define a context as a snapshot of the parser stacks. We define |
1329 | the initial context for a lookahead as the context in which the |
1330 | parser initially examines that lookahead in order to select a |
1331 | syntactic action. Thus, if the lookahead eventually proves |
1332 | syntactically unacceptable (possibly in a later context reached via a |
1333 | series of reductions), the initial context can be used to determine |
1334 | the exact set of tokens that would be syntactically acceptable in the |
1335 | lookahead's place. Moreover, it is the context after which any |
1336 | further semantic actions would be erroneous because they would be |
1337 | determined by a syntactically unacceptable token. |
1338 | |
1339 | YY_LAC_ESTABLISH should be invoked when a reduction is about to be |
1340 | performed in an inconsistent state (which, for the purposes of LAC, |
1341 | includes consistent states that don't know they're consistent because |
1342 | their default reductions have been disabled). Iff there is a |
1343 | lookahead token, it should also be invoked before reporting a syntax |
1344 | error. This latter case is for the sake of the debugging output. |
1345 | |
1346 | For parse.lac=full, the implementation of YY_LAC_ESTABLISH is as |
1347 | follows. If no initial context is currently established for the |
1348 | current lookahead, then check if that lookahead can eventually be |
1349 | shifted if syntactic actions continue from the current context. |
