Bison directive from the Bison file to the invocation of this
macro, so that these directives are passed to
AT_BISON_OPTION_PUSHDEFS to get correct help macros.
Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
Move the AT_SETUP/AT_CLEANUP outside, to report as test title
the extra Bison directives instead of the whole series.
Change the grammar so that there are recoverable errors, and
unrecoverable errors. Now we can have the parser give up before
consuming the whole input. As a result we now can observe that
the lookahead is freed when needed.
Change the parser source to parse argv[1] instead of a hard coded
string.
Simplify yylex, and give a value and location to EOF.
Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
passed directives already coded in the file.
Add some tests to check the location of "error".
For some tests, the C++ parser is correct, and not yacc.c.
For other tests, they provide different, but unsatisfying, values,
so keep the C++ value so that at least one parser is "correct"
according to the test suite.
(Actions after errors): Remove, this is subsumed by the
AT_CHECK_PRINTER_AND_DESTRUCTOR series.
argument, an informative message.
Call YY_SYMBOL_PRINT.
Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
* data/lalr1.cc (destruct_): Likewise.
In addition, no longer depend on b4_yysymprint_generate and
b4_yydestruct_generate to generate these functions, do it "by
hand".
invoked, yydestruct the lookahead.
* tests/calc.at (Calculator $1): Update the expected lengths of
traces: there is an added line for the discarded lookahead.
* doc/bison.texinfo (Destructor Decl): Some rewording.
Define "discarded" symbols.
(YYDSYMPRINTF): Rename as...
(YY_SYMBOL_PRINT): this.
* data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
two.
Use it instead of direct symprint_ calls.
(yybackup): Tweak the "Now at end of input" case to match yacc.c's
one.
(gnulib_modules): Add xalloc-die.
Set LC_ALL=C so that file names sort consistently.
Prefer the gnulib copies of gettext.m4, glibc21.m4,
inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
uintmax_t.m4, ulonglong.m4.
(intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
po.m4 since we are now using _gl.m4 instead.
AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
UNION-FLAG. All callers changed.
(_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
Use type char, not unsigned int, when declaring an array of char;
this lets us remove a cast.
(Printers and Destructors): Add non-%union test cases.
