Subject: tests: handle locations in the generic yyerror functions.
X-Git-Tag: v2.6~56
X-Git-Url: https://git.saurik.com/bison.git/commitdiff_plain/7490994123d5cae9ae69547f4e121b24412b2760

tests: handle locations in the generic yyerror functions.

* tests/local.at (AT_YYERROR_DECLARE_EXTERN, AT_YYERROR_DECLARE)
(AT_YYERROR_DEFINE): Handle locations for C and C++.
* tests/calc.at: Use it for C++ (as C has extra arguments which
are not yet handled by AT_BISON_OPTION_PUSHDEFS).
* tests/actions.at: Adjust.
