its argument.
Reported by Peter Hámorský.
 2001-12-05 10:58:44 +00:00
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.

(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.

 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 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

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

Akim Demaille 19f8d30b9c * src/state.h (SHIFT_SYMBOL): 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.

to improve readability.

 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

 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

 2001-11-28 14:57:44 +00:00

then bits in words, loop over bits in array.
 2001-11-28 14:57:16 +00:00
Akim Demaille a816bf3eac * src/closure.c (closure): No longer optimize the special case 
where all the bits of `ruleset[r]' are set to 0, to make the code
clearer.
 2001-11-28 14:57:02 +00:00
Akim Demaille 2ce6476804 * src/closure.c (closure): r' and c' are new variables, used to 
de-obfuscate accesses to RULESET and CORE.
 2001-11-28 14:55:38 +00:00

Akim Demaille 8639df64a6 * src/LR0.c (new_state, get_state): Complete TRACE code.
