bison 3 apparently made a backwards incompatible change, dropped YYLEX_PARAM/YYPARSE_PARAM support and instead needs %param or %lex-param and %parse-param. Furthermore, there is no easy way to conditionalize on bison version in the *.y files. While e.g. glibc bumped bison requirement and just has the bison 3 compatible version, Richi said there are still systems with older bison where we want to build gcc. So, this patch instead determines during configure bison version, and depending on that when building plural.c (if building it at all) tweaks what is passed over to bison if needed. Tested with both bison 3 and bison 1.35, in each case with reconfiguring intl and building with make all-yes (as in my setup intl isn't normally used). 2020-04-16 Jakub Jelinek <jakub@redhat.com> PR bootstrap/92008 * configure.ac: Add check for bison >= 3, AC_DEFINE HAVE_BISON3 and AC_SUBST BISON3_YES and BISON3_NO. * Makefile.in (.y.c): Prefix $(YACC) invocation with @BISON3_NO@, add @BISON3_YES@ prefixed rule to adjust the *.y source using sed and adjust output afterwards. * plural-exp.h (PLURAL_PARSE): If HAVE_BISON3 is defined, use struct parse_args * type for arg instead of void *. * plural.y: Add magic /* BISON3 ... */ comments with bison >= 3 directives. (YYLEX_PARAM, YYPARSE_PARAM): Don't define if HAVE_BISON3 is defined. (yylex, yyerror): Adjust prototypes and definitions if HAVE_BISON3 is defined. * plural.c: Regenerated. * config.h.in: Regenerated. * configure: Regenerated. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
