Akim Demaille 25a46077de * src/conflicts.c (count_rr_conflicts): The previous RR conflicts 
patch was improperly applied: fix it.
 2002-01-07 08:42:59 +00:00
Akim Demaille 62d3162c4c Revert the previous patch which was meant for the trunk only. 2002-01-07 08:40:29 +00:00
Akim Demaille 3f2f7848cc * src/reader.c (parse_braces): Don't fetch the next char, the 
convention is to fetch on entry.
* tests/torture.at (GNU Cim Grammar): Reintroduce their weird
'switch' without a following semicolon.
* tests/regression.at (braces parsing): New.
 2002-01-06 20:59:30 +00:00
Akim Demaille c4267a3d35 Bison is dead wrong in its RR conflict reports. 
* tests/torture.at (GNU Cim Grammar): New.
* src/conflicts.c (count_rr_conflicts): Fix.
 2002-01-06 20:59:12 +00:00
Akim Demaille ae774286e8 Creating package.m4 from configure.ac causes too many problems. 
* tests/Makefile.am (package.m4): Create it by hand,
AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
 2002-01-06 20:57:20 +00:00
Akim Demaille 43f8a3245a Regen. 2002-01-06 20:56:42 +00:00
Akim Demaille 38612b10a3 * src/files.h: Add it prototype. 2002-01-03 13:55:09 +00:00
Akim Demaille ffc03584ad * src/files.c, src/files.h (strsuffix): Not static. 
* src/conflicts.c (conflicts_print): Don't consider it is an error
to have a %expectation violation on a file ending by `plural.y'.
Eek.
 2002-01-03 13:39:20 +00:00
Akim Demaille dd3c3f3006 * tests/bison.in: Adjust to CVS Autoconf. 
* 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.

Akim Demaille ca69f83c53 Version 1.30i. 2002-01-03 10:42:17 +00:00
Akim Demaille b06c1dfb75 Update. 2002-01-03 10:40:03 +00:00
Akim Demaille 7525f95ed5 * src/bison.simple (YYSTDERR): Remove, replace `stderr'. 
The ISO C++ standard is extremely clear about it: stderr is
considered a macro, not a regular symbol (see table 94 `Header
<cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
Therefore std:: does not apply to it.  It still does with fprintf.
Also, s/cstdio.h/cstdio/.
 2002-01-03 09:48:08 +00:00
Akim Demaille 1daed0de8a * lib/quotearg.c: Use #include "..."' instead of #include <...>' 
for non system headers.
 2002-01-03 09:27:34 +00:00
Akim Demaille 32e175835b Regen. 2002-01-03 09:24:59 +00:00
Akim Demaille ea04a14c5c * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special 
cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
Sparc, as they were causing more porting problems than the
(minor) performance improvement was worth.
 2001-12-27 18:30:40 +00:00
Akim Demaille d6b12c2d8b * src/output.c (output_short_table, output_short_or_char_table): 
Change the prototype to use `int' for array ranges: some
invocations do pass an int, not a short.
Reported by Wayne Green.
 2001-12-27 18:28:23 +00:00
Akim Demaille f4ffa313a2 Regen. 2001-12-22 15:13:48 +00:00
Akim Demaille 1214dfb03b Some actions of web2c.y are improperly triggered. 
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.
 2001-12-22 14:44:25 +00:00
Akim Demaille 55b4181996 Reductions in web2c.y are improperly reported. 
Reported by Mike Castle.

Akim Demaille 36791b5576 Version 1.30h. 2001-12-18 09:46:36 +00:00
Akim Demaille dba44a1367 Update. 2001-12-18 09:42:58 +00:00
Akim Demaille d4593e87be Some host fail on `assert (!"foo")', which expands to 
((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
Reported by Nelson Beebee.
* src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
`#define it_succeeded 0' and `assert (it_succeeded)'.
 2001-12-18 09:33:23 +00:00
Akim Demaille f30e1ab65c * src/nullable.c (set_nullable): Useless rules must be skipped, 
otherwise, since we range over their symbols, we might look at a
nonterminal which no longer ``exists'', i.e., it is not counted in
`nvars', hence we overflow our arrays.
 2001-12-15 16:22:13 +00:00
Akim Demaille 52e9776027 * src/reader.c (copy_action): When --yacc, don't append a `;' 
to the user action: let it fail if lacking.
Suggested by Aharon Robbins and Tom Tromey.

Akim Demaille c884affb0b Update. 2001-12-13 11:06:18 +00:00
Akim Demaille f7e7f57941 The computation of nullable is broken: it doesn't handle empty 
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.
 2001-12-13 10:59:37 +00:00
Akim Demaille 69dc1147ba * src/complain.h, src/complain.c: Remove error_one_per_line, rely 
on that of lib/error.c.

Akim Demaille 88f06d2beb Some hosts don't like `/' in includes. 
* src/system.h: Include libgettext.h without qualifying the path.
* src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
$(top_srcdir).

Akim Demaille ed45e93ed8 Bison dumps core on bash.y. 
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.
 2001-12-10 08:43:38 +00:00

its argument.
Reported by Peter Hámorský.

Akim Demaille b9866ce4da Regen. 2001-12-05 09:30:34 +00:00
Akim Demaille b32ba448c8 * src/conflicts.c (err_table): Remove. 
(resolve_sr_conflict): Adjust.
* src/lalr.h (state_t.reduction_table, state_t.shift_table):
Rename as...
(state_t.reductions, state_t.shifts): this.
 2001-12-05 09:24:54 +00:00
Akim Demaille 5844cd0cfa * src/reduce.c (reduce_grammar_tables): No longer disable the 
removal of useless rules via CPP but via `if (0)', so that the
compiler still check the code is valid.
For instance, it should have noticed `rline' no longer exists: use
the `line' member of rule_t.
* src/gram.c (dummy, rline): Remove, unused.
 2001-12-05 09:24:35 +00:00
Akim Demaille 0fc1a97d9f * src/output.c (pack_vector): Use assert, not berror. 
* src/main.c (berror): Remove, unused.
 2001-12-05 09:24:21 +00:00
Akim Demaille 84b6f48351 New experimental feature: if --verbose --trace output all the 
items of a state, not only its kernel.
* src/print.c (print_core): If `trace_flag', then invoke closure
before outputting the items of the state (print_core is no longer
a correct name them).
(print_results): Invoke new_closure/free_closure if needed.
 2001-12-05 09:24:06 +00:00
Akim Demaille b6a70d99a6 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount. 
* src/closure.c, src/closure.h (itemsetsize): Rename as...
(nitemset): for consistency with the rest of the project.
 2001-12-05 09:23:52 +00:00
Akim Demaille 66d35de779 * src/closure.c (print_closure): Improve. 
(closure): Use it for printing input and output.
 2001-12-05 09:23:38 +00:00
Akim Demaille 5e5b240715 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are 
indexed by nonterminals.
 2001-12-05 09:23:24 +00:00
Akim Demaille aaf7be2c4b * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of 
what it was!).
* src/warshall.h: Remove accidental duplication of the content.
 2001-12-05 09:23:10 +00:00
Akim Demaille 0ea80316a9 * src/closure.c (set_fderives): De-obfuscate. 2001-12-05 09:22:55 +00:00
Akim Demaille 09b2117db7 * src/closure.c (print_firsts, print_fderives): De-obfuscate. 2001-12-05 09:22:40 +00:00
Akim Demaille 78fc5ce865 * src/closure.c (set_firsts): De-obfuscate. 2001-12-05 09:22:27 +00:00
Akim Demaille 766ffc1523 * src/output.c (action_row): De-obfuscate 
using the good o' techniques: arrays not pointers, variable
locality, BITISSET, RESETBIT etc.
 2001-12-05 09:22:14 +00:00
Akim Demaille 06a2f464b1 Pessimize the code to simplify it: from now on, all the states 
have a valid SHIFTS, which NSHIFTS is possibly 0.
* src/LR0.c (shifts_new): Be global and move to..
* src/state.c, src/state.h: here.
* src/conflicts, src/lalr.c, src/output.c, src/print.c,
* src/print_graph: Adjust.
 2001-12-05 09:21:55 +00:00
Akim Demaille 15ab9127f5 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New. 
* src/conflicts.c: Use it.
Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
incorrectly ``simplified''.
 2001-12-05 09:21:15 +00:00
Akim Demaille 32f18df511 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate 
using the good o' techniques: arrays not pointers, variable
locality, BITISSET, RESETBIT etc.
 2001-12-05 09:20:55 +00:00
Akim Demaille 19f8d30b9c * src/state.h (SHIFT_SYMBOL): New.

 2001-12-05 09:20:41 +00:00
Akim Demaille 7b106ce5f0 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)

arrays not pointers, variable locality, BITISSET.
 2001-12-05 09:20:22 +00:00
Akim Demaille b5c15946a1 * src/conflicts.c (print_reductions): Arrays, not pointers.

Akim Demaille 2883204382 * src/conflicts.c (print_reductions): Improve variable locality. 2001-12-05 09:19:13 +00:00
Akim Demaille 825b9e4ef4 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New. 
* src/lalr.c: Use them.
 2001-12-05 09:18:57 +00:00
Akim Demaille 57339f0421 * src/LR0.c (augment_automaton): Formatting changes. 
Better variable locality.
 2001-12-05 09:18:39 +00:00
Akim Demaille 963c0cf62f * src/lalr.c (matrix_print): New. 
(transpose): Use it.
Use arrays instead of pointers.
 2001-12-05 09:18:25 +00:00
Akim Demaille 6a1e01f060 * src/lalr.c (maxrhs): Move to... 
* src/gram.c, src/gram.h (ritem_longest_rhs): here.
* src/lalr.c (build_relations): Adjust.
 2001-12-05 09:18:12 +00:00
Akim Demaille 4cecb5a248 * src/lalr.c (transpose): Free the memory allocated to the 
argument, as it is replaced by the results by the unique caller.
(build_relations): Merely invoke transpose: it handles the memory
deallocation.
Improve variable locality.
Avoid variables used as mere abbreviations.
(compute_lookaheads): Use arrays instead of pointers.
 2001-12-05 09:17:50 +00:00
Akim Demaille 76c97f6a39 * src/lalr.c (initialize_F): Improve variable locality. 
Avoid variables used as mere abbreviations.
 2001-12-05 09:17:34 +00:00
Akim Demaille e4ef7aa1c9 * src/derives.c (print_derives): Display the ruleno. 
* src/lalr.c (initialize_F, transpose): Better variable locality
to improve readability.
Avoid variables used as mere abbreviations.
 2001-12-05 09:17:20 +00:00
Akim Demaille 3557477440 * src/lalr.c (traverse): Use arrays instead of pointers. 2001-12-05 09:17:05 +00:00
Akim Demaille 4b412c9eca * src/nullable.c (set_nullable): Use a for loop to de-obfuscate 
the handling of squeue.
`symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
 2001-12-05 09:16:51 +00:00
Akim Demaille fa7f94f217 Because useless nonterminals are now kept alive (instead of being 
`destroyed'), we now sometimes examine them, and store information
related to them.  Hence we need to know their number, and adjust
memory allocations.
* src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
static.
* src/LR0.c (allocate_itemsets): The memory allocated to
`symbol_count' was used for two different purpose: once to count
the number of occurrences of each symbol, and later reassigned to
`shift_symbol', containing the symbol that can be shifted from a
given state.
Deobfuscate, i.e., allocate, use and free `symbol_count' here
only, and...
(new_itemsets): Allocate `shift_symbol' here.
(allocate_itemsets): symbol_count includes useless nonterminals.
Make room for them.
(free_storage): Use `free', not `XFREE', for pointers that cannot
be null.
 2001-12-05 09:16:37 +00:00
Akim Demaille d854cc9e5a * src/nullable.c (set_nullable): Deobfuscate the handling of 
ritem.
`symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
 2001-12-05 09:16:22 +00:00
Akim Demaille 2dfb4daf9b * src/gram.c, src/gram.h (ritem_print): New. 
* src/gram.c (dummy): Remove, now there is actual code in gram.c.
(This useless function was defined only to work around VMS linkers
that can't handle compilation units with variables only).
* src/reduce.c (dump_grammar): Use it to trace the construction of
ritem.
 2001-12-05 09:16:07 +00:00
Akim Demaille a69f6fa569 * configure.in (WARNING_CFLAGS): Add -Werror when possible. 
(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.
 2001-11-30 14:23:47 +00:00
Akim Demaille 3757d84e90 * lib/quotearg.h (quotearg_n, quotearg_n_style): 
First arg is int, not unsigned.
* lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
(SIZE_MAX, UINT_MAX): New macros.
(quotearg_n_options): Abort if N is negative.
Avoid overflow check on hosts where size_t is 64 bits and int
is 32 bits, as overflow is impossible there.
Fix off-by-one typo that caused unnecessary reallocation.
 2001-11-30 14:04:22 +00:00

Akim Demaille fc7ddd2818 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty 
if body instead of `;' to pacify GCC's warnings.

(Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
 2001-11-30 10:45:45 +00:00
Akim Demaille ea451a17d7 * src/reduce.c (nonterminals_reduce): Instead of throwing away 
useless nonterminals, move them at the end of the symbol arrays.
(reduce_output): Adjust.
* tests/reduce.at (Useless Nonterminals): Adjust.
 2001-11-30 10:45:28 +00:00
Akim Demaille 24b1e65f04 * src/reduce.c: Various comment/formatting changes. 
(nonterminals_reduce): New, extracted from...
