the only way this function was invoked is if the default action |
|

1331 |
is an error action. In that case, don't check for expected |
|
|
1332 |
tokens because there are none. |
|
|
1333 |
- The only way there can be no lookahead present (in yychar) is if |
|
|
1334 |
this state is a consistent state with a default action. Thus, |
|
|
1335 |
detecting the absence of a lookahead is sufficient to determine |
|
|
1336 |
that there is no unexpected or expected token to report. In that |
|
|
1337 |
case, just report a simple "syntax error". |
|
|
1338 |
- Don't assume there isn't a lookahead just because this state is a |
|
|
1339 |
consistent state with a default action. There might have been a |
|
|
1340 |
previous inconsistent state, consistent state with a non-default |
|
|
1341 |
action, or user semantic action that manipulated yychar. |
|
|
1342 |
- Of course, the expected token list depends on states to have |
|
|
1343 |
correct lookahead information, and it depends on the parser not |
|
|
1344 |
to perform extra reductions after fetching a lookahead from the |
|
|
1345 |
scanner and before detecting a syntax error. Thus, state merging |
|
|
1346 |
(from LALR or IELR) and default reductions corrupt the expected |
|
|
1347 |
token list. However, the list is correct for canonical LR with |
|
|
1348 |
one exception: it will still contain any token that will not be |
|
|
1349 |
accepted due to an error action in a later state. |
