Paul Eggert e64fec0a0f (How Can I Reset the Parser): Renamed from `How Can I Reset

Paul Eggert 907e3bc851 (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.

Paul Eggert 26ec81e097 Don't pass C-only options to g++. 
Fix YYFILL in GLR parsers to conform to the C standard.
Fix infinite loops in yacc.c, and add a test case.
 2003-06-02 07:29:18 +00:00

Define 'alarm' to do nothing if unistd.h is not available.
Add a new rule "exp: '-' error;" to test the above change to
data/yacc.c.  Use 'alarm' to abort any test taking longer than
10 seconds, as it's probably looping.
(AT_CHECK_CALC): Test recovery from error in new grammar rule.
Also, the new yacc.c generates two fewer diagnostics for an
existing test.
 2003-06-02 03:58:34 +00:00
Paul Eggert a6b89bb2dc (YYERROR): Now just 'goto yyerrorlab', since the 
macro's size was becoming unwieldy.
(yyerrlab): Do not discard an empty lookahead symbol, as this
might destroy garbage.
(yyerrorlab): New label, with the old contents of YYERROR,
plus the following change: pop the stack of rhs corresponding
to the production that invoked YYERROR.  That is how Yacc
behaves, and POSIX requires this behavior.
(yyerrlab1): Use YYPOPSTACK instead of its definiens.
