* Avoid compiler warningsAkim Demaille2018-05-121-1/+1
| | | | | | | | | | | | | | At least GCC 7.3, with -O1 or -O2 (but not -O0 or -O3) generates warnings with -Wnull-dereference when using yyformat: it fails to see yyformat cannot be null. Reported by Frank Heckenbach, https://savannah.gnu.org/patch/?9620. * configure.ac: Use -Wnull-dereference if supported. * data/glr.c, data/lalr1.cc, data/yacc.c: Define yyformat in such a way that GCC cannot not see that yyformat is defined. Using `default: abort();` also addresses the issue, but forces the inclusion of `stdlib.h`, which we avoid.
* tests: beware that clang warns about "#define private public"Akim Demaille2015-08-121-1/+6
| | | | | | | We use this trick to write some test about internal details. But since we use -Werror, clang++ 3.6 dies issueing a warning about it. * configure.ac (warn_tests): Disable this warning.
* tests: update our Valgrind suppression filesAkim Demaille2015-08-121-7/+8
| | | | | | | | * build-aux/linux-gnu.valgrind, build-aux/darwin11.4.0.valgrind: Rename as... * build-aux/Linux.valgrind, build-aux/Darwin.valgrind: these. * build-aux/Linux.valgrind: Add suppression clause. * configure.ac: Update. * tests/local.mk: Use it.
* build: re-enable compiler warnings, and fix themAkim Demaille2015-01-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | There are warnings (-Wextra) in generated C++ code: ltlparse.cc: In member function 'ltlyy::parser::symbol_number_type ltlyy::parser::by_state::type_get() const': ltlparse.cc:452:33: warning: enumeral and non-enumeral type in conditional expression return state == empty_state ? empty_symbol : yystos_[state]; Reported by Alexandre Duret-Lutz. It turns out that -Wall and -Wextra were disabled because of a stupid typo. * configure.ac: Fix the stupid typo. * data/lalr1.cc, src/AnnotationList.c, src/InadequacyList.c, * src/ielr.c, src/print.c, src/scan-code.l, src/symlist.c, * src/symlist.h, src/symtab.c, src/tables.c, tests/actions.at, * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at, * tests/named-refs.at, tests/torture.at: Fix warnings, mostly issues about variables used only with assertions, which are disabled with -DNDEBUG.
* build: don't try to generate docs when cross-compilingAkim Demaille2015-01-051-0/+3
| | | | | | | | | When cross-compiling don't run the generated bison to update the docs. Reported by Aaro Koskinen. <http://lists.gnu.org/archive/html/bison-patches/2014-03/msg00000.html> * configure.ac (CROSS_COMPILING): New. * doc/local.mk: Use it.

* package: install the examplesAkim Demaille2013-12-091-1/+4
| | | | | | | | | | | Currently, we do not install the various examples extracted from the documentation. Let's do it, as they are useful starting points. * configure.ac: When --enable-gcc-warnings is set, enable ENABLE_GCC_WARNINGS. * examples/extexi: No longer issue synclines by default. * examples/local.mk: Except if ENABLE_GCC_WARNINGS. * examples/calc++/local.mk, examples/mfcalc/local.mk, * examples/rpcalc/local.mk: Install the example files.

| | | | | | * configure.ac: Require Automake 1.14. * examples/calc++/local.mk, examples/local.mk, examples/mfcalc/local.mk, * examples/rpcalc/local.mk, tests/local.mk: Use %D% and %C%.
* install: do not install yacc.1 when --disable-yaccAkim Demaille2013-10-221-10/+1
| | | | | | | * configure.ac (ENABLE_YACC): New conditional. (YACC_SCRIPT, YACC_LIBRARY): Remove. * lib/local.mk, src/local.mk: Use the former instead of the latter. * doc/local.mk: Use ENABLE_YACC to avoid installing yacc.1.
* c++: fix generated doxygen commentsAkim Demaille2013-10-221-1/+1
| | | | | * configure.ac: Enable -Wdocumentation if supported. * data/lalr1.cc: Fix comments.
* build: examples/calc++/calc++ requires flexPaul Eggert2013-10-211-0/+2
| | | | | | * configure.ac (FLEX_CXX_WORKS): New AM_CONDITIONAL. * examples/calc++/local.mk (examples/calc++/calc++): Build if FLEX_CXX_WORKS, not BISON_CXX_WORKS.
* build: don't require flex for ordinary buildsPaul Eggert2013-08-241-1/+4
| | | | | | | * configure.ac (LEX): Don't fail if this is lex, as flex is not required for ordinary builds. Instead, issue a warning and substitute a no-op LEX. Reported by Michael Felt in <http://lists.gnu.org/archive/html/bug-bison/2013-08/msg00009.html>.

* tests: enable -Wsign-compare and fix corresponding warningsAkim Demaille2013-04-191-1/+1
| | | | | | | | | | | | | | | | | -Wsign-compare was disabled for bison's own code, following gnulib's approach. However, the generated parsers should not trigger such warnings. Reported by Efi Fogel. http://lists.gnu.org/archive/html/help-bison/2013-04/msg00018.html See also http://stackoverflow.com/questions/16101062 for the weird "-(unsigned)i" piece of code. * configure.ac (warn_tests): Enable -Wsign-compare. * data/location.cc (position::add_): New. (position::lines, position::columns): Use it. * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): Fix signedness issues.
* tests: fix failures with G++ 4.8 in Flex scannerAkim Demaille2013-02-191-1/+3
| | | | | | | * configure.ac (WARN_NO_NULL_CONVERSION_CXXFLAGS): Rename as... (FLEX_SCANNER_CXXFLAGS): this. Pass -Wno-zero-as-null-pointer-constant to G++ if it supports it. * examples/calc++/local.mk: Adjust.

* variants: avoid type punning issueTheophile Ranquet2013-02-011-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | This is based on what is recommended by both Scott Meyers, in 'Effective C++', and Andrei Alexandrescu and Herb Sutter in 'C++ Coding Standards'. Use a static_cast on void* rather than directly use a reinterpret_cast, which can have nefarious effects on objects. However, even though following this guideline is good practice in general, I am not quite sure how relevant it is when applied to conversions from POD to objects. Actually, it might very well be the opposite: isn't this exactly what reinterpret_cast is for? What we really want *is* to transmit the memory map as a series of bytes, which, if I am correct, falls into the kind of "low level" hack for which this cast is meant. In any case, this silences the warning, which will be greatly appreciated by anyone using variants with a compiler supporting -fstrict-aliasing. * data/variant.hh (as): Here. * tests/c++.at (Exception safety, C++ Variant-based Symbols, Variants): Don't use NO_STRICT_ALIAS_CXXFLAGS (revert commit ddb9db15), as type punning is no longer an issue. * tests/atlocal.in, configure.ac (NO_STRICT_ALIAS_CXXFLAGS): Remove definition. * examples/local.mk (NO_STRICT_ALIAS_CXXFLAGS): Remove from AM_CXXFLAGS. * doc/bison.texi: Don't mention type punning issues.
* build: avoid clang's colored diagnostics in the test suiteAkim Demaille2013-01-301-5/+14
| | | | | | | | | | | The syncline tests, which try to recognize compiler diagnostics, are confused by escapes for colors. * configure.ac (warn_tests): New, to factor the warnings for both C and C++ tests. Add -fno-color-diagnostics to it. * tests/local.at (AT_TEST_TABLES_AND_PARSE): Do not remove glue together compiler flags.
* build: please Clang++ 3.2+ on Flex scannersAkim Demaille2013-01-301-0/+2
| | | | | | | | | | | | | Clang++, with -Wall, rejects code generated by Flex (for C scanners): CXX examples/calc++/examples_calc___calc__-calc++-scanner.o In file included from examples/calc++/calc++-scanner.cc:1: error: implicit conversion of NULL constant to 'bool' [-Werror,-Wnull-conversion] if ( !

| | | | | | | | | | | | | | | | | | | | Bison uses "/usr/bin/perl" or "perl" in several places, and it does not appear to be a problem. But, at least to make it simpler to change PERL on the make command line, check for perl in configure. * configure.ac (PERL): New. * doc/Doxyfile.in, doc/local.mk, examples/local.mk, * tests/bison.in: Use it.
