+
+ * src/LR0.c (augment_automaton): Now that all states have shifts,

+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/lalr.c (set_state_table): Move to...

+
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+

+ * src/LR0.c (insert_start_shift): Rename as...
+ (insert_start_shifting_state): this.
+ (insert_eof_shifting_state, insert_accepting_state): New.
+ (augment_automaton): Adjust.
+ Better locality of the variables.
+ When looking if the start_symbol is shifted from the initial

+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/getargs.h: Don't declare `spec_name_prefix' and

+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ Now that states have a complete set of members, the linked list of

+2001-12-05 Akim Demaille <akim@epita.fr>
+
+ 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

+ (print_results): Invoke new_closure/free_closure if needed.
+
+2001-12-05 Akim Demaille <akim@epita.fr>
+
+ * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.

+2001-12-05 Akim Demaille <akim@epita.fr>
+
+ * src/lalr.c (transpose): Free the memory allocated to the

+
+2001-12-05 Akim Demaille <akim@epita.fr>
+
+ Because useless nonterminals are now kept alive (instead of being

+ 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 Akim Demaille <akim@epita.fr>
+
+ * src/nullable.c (set_nullable): Deobfuscate the handling of

+
+ * 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.
+
+2001-12-04 Paul Eggert <eggert@twinsun.com>
+
+ * src/bison.simple (union yyalloc): Change member names
+ to be the same as the stack names.
+ (yyparse): yyptr is now union yyalloc *, not char *.
+ (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
+ and may generate better code on some machines.
+ (yystpcpy): Use prototype if __STDC__ is defined, not just
+ if __cplusplus is defined.
+
+2001-11-30 Akim Demaille <akim@epita.fr>
+

+ before being defined.
+
+2001-11-27 Paul Eggert <eggert@twinsun.com>
+

+ * 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.
+
+2001-11-29 Paul Eggert <eggert@twinsun.com>
+
+ Name space cleanup in generated parser.
+
+ * doc/bison.texinfo (Bison Parser): Discuss system headers
+ and their effect on the user name space.
+
+ * src/bison.simple:
+ (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,

+
+ (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
+ on user names when possible.
+
+ (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.

+
+ (<stdlib.h>): Include if we will use malloc, and if standard C or C++.

+
+ (yystrlen, yystpcpy): New functions.
+
+ (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
+ All uses changed.
+
+ (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
+ instead of relying on string.h functions. Use YYSTACK_ALLOC
+ and YYSTACK_FREE instead of malloc and free.
+
+2001-11-30 Akim Demaille <akim@epita.fr>
+
+ * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
+ before their first uses.
+ (YYBISON, YYPURE): Move to the top of the output.
+
+2001-11-30 Akim Demaille <akim@epita.fr>

+ * tests/reduce.at (Useless Nonterminals): Fix.
+
+2001-11-30 Akim Demaille <akim@epita.fr>
+

+
+2001-11-30 Akim Demaille <akim@epita.fr>
+
+ Instead of mapping the LHS of unused rules to -1, keep the LHS

+ (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
+ New macros.
+ (union yyalloc): New type.
+ (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
+ an arbitrary restriction on hosts where size_t is wider than int.
+
+ (yyparse): Don't dump core if alloca or malloc fails; instead, report
+ a parser stack overflow. Allocate just one block of memory for all
+ three stacks, instead of allocating three blocks; this typically is
+ faster and reduces fragmentation.
+
+ Do not limit the number of items in the stack to a value that fits

+ size_t and 32-bit int.
+
+2001-11-29 Marc Autret <autret_m@epita.fr>
+
+ * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead

+2001-11-28 Akim Demaille <akim@epita.fr>
+
+ * src/closure.c (closure): No longer optimize the special case
