* * tests/bison.in: Adjust to CVS Autoconf.Akim Demaille2002-01-033-19/+5
| | | | | | | * tests/calc.at (exp): We no longer need to special case GCC as the warning flags are passed by configure. * tests/atlocal.in: Adjust. * configure.in: Bump to 1.30j.
* Regen.Akim Demaille2002-01-031-4/+4

* Some actions of web2c.y are improperly triggered.Akim Demaille2001-12-221-4/+129
| | | | | | | | Reported by Mike Castle. * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/. * tests/regression.at (Web2c): Rename as... (Web2c Report): this. (Web2c Actions): New.
* Reductions in web2c.y are improperly reported.Akim Demaille2001-12-221-0/+105
| | | | | | Reported by Mike Castle. * src/conflicts.c (print_reductions): Fix. * tests/regression.at (Web2c): New.
* The computation of nullable is broken: it doesn't handle emptyAkim Demaille2001-12-136-77/+536
| | | | | | | | | | | | | | | | | | RHS's properly. * tests/torture.at (GNU AWK Grammar): New. * tests/sets.at (Nullable): New. * src/nullable.c (set_nullable): Instead of blindly looping over `ritems', loop over the rules, and then over their rhs's. Work around Autotest bugs. * src/warshall.c (bitmatrix_print): Don't use `+--+' as table frame, because Autotest understand lines starting with a `+' as traces from the shell. Then, they are not processed properly. Admittedly an Autotest bug, but we don't have time to wait for Autotest to catch up. * tests/regression.at (Broken Closure): Adjust to the new table frames. Move to... * tests/sets.at: here.
* Bison dumps core on bash.y.Akim Demaille2001-12-101-0/+75
| | | | | | | | | Reported by Pascal Bart. * src/warshall.c (bitmatrix_print): New. (TC): Use it. When performing a transitive closure R(i, j) && R(j, k) => R(i, k), j must be the outer loop. * tests/regression.at (Broken Closure): New.
* * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I andAkim Demaille2001-12-051-1/+1
| | | | | its argument. Reported by Peter Hámorský.
* * configure.in (WARNING_CFLAGS): Add -Werror when possible.Akim Demaille2001-11-301-1/+1
| | | | | | | | | (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU Gettext doesn't compile cleanly, and dies with -Werror. * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS): Include WARNING_CFLAGS here. * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared before being defined.
* Instead of mapping the LHS of unused rules to -1, keep the LHSAkim Demaille2001-11-301-0/+98

* * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.Akim Demaille2001-11-284-2/+109
| | | | | | * src/reduce.c (reduce_grammar_tables): Do not free useless tags, as all tags are free'ed afterwards. From Enrico Scholz.

* * src/conflicts.c (conflicts_print): Don't complain at all whenAkim Demaille2001-11-261-3/+1
| | | | | | there are no reduce/reduce conflicts, and as many shift/reduce conflicts as expected. * tests/regression.at (%expect right): Adjust.
* Attaching lineno to buckets is stupid, since only one copy of eachAkim Demaille2001-11-231-4/+6

* * tests/calc.at, tests/output.at, tests/regression.at,Akim Demaille2001-11-146-21/+24
| | | | | | | | * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g: now the tests are run in private dirs, therefore AC_CLEANUP and family can be simplified to 0-ary. * tests/atlocal.in: Now that we run `elsewhere' than in tests/, use abs. path to find config.h.
* %expext was not functioning at all.Akim Demaille2001-11-122-1/+61
| | | | | | | | | | * src/conflicts.c (expected_conflicts): Set to -1. (conflict_report): Use ngettext.
