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