<http://lists.gnu.org/archive/html/bison-patches/2009-12/msg00024.html>
|
|
for details. YYERROR is fine as it does not invoke this
|
|
function.
|
|
- If this state is a consistent state with a default action, then
|
|
the only way this function was invoked is if the default action
|
|
is an error action. In that case, don't check for expected
|
|
tokens because there are none.
|
|
- The only way there can be no lookahead present (in yychar) is if
|
|
this state is a consistent state with a default action. Thus,
|
|
detecting the absence of a lookahead is sufficient to determine
|
|
that there is no unexpected or expected token to report. In that
|
|
case, just report a simple "syntax error".
|
|
- Don't assume there isn't a lookahead just because this state is a
|
|
consistent state with a default action. There might have been a
|
|
previous inconsistent state, consistent state with a non-default
|
|
action, or user semantic action that manipulated yychar.
|
|
- Of course, the expected token list depends on states to have
|
|
correct lookahead information, and it depends on the parser not
|
|
to perform extra reductions after fetching a lookahead from the
|
|
scanner and before detecting a syntax error. Thus, state merging
|
|
(from LALR or IELR) and default reductions corrupt the expected
|
|
token list. However, the list is correct for canonical LR with
|
|
one exception: it will still contain any token that will not be
|
|
accepted due to an error action in a later state.
