changed to use xcalloc, xnmalloc, xnrealloc, respectively,
unless otherwise specified below.
* src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
to allocate kernel_base, kernel_items, kernel_size, since
they needn't be initialized to 0.
(allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
* src/closure.c (new_closure): Likewise, for itemset.
* src/derives.c (derives_compute): Likewise, for delts, derives, q.
* src/lalr.c (set_goto_map): Likewise, for temp_map.
(initialize_F): Likewise, for reads, edge, reads[i], includes[i].
(build_relations): Likewise for edge, states1, includes.
* src/nullable.c (nullable_compute): Likewise, for squeue, relts.
* src/reader.c (packgram): Likewise, for ritem, rules.
* src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
* src/relation.c (relation_digraph): Likewise for VERTICES.
(relation_transpose): Likewise for new_R, end_R.
* src/symtab.c (symbols_token_translations_init): Likewise for
token_translations.
* src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
(token_actions): Likewise for yydefact, actrow, conflrow,
conflict_list.
(save_column): Likewise for froms[symno], tos[symno].
(goto_actions): Likewise for state_count.
(pack_table): Likewise for base, pos, check.
(tables_generate): Likewise for width.
* src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
for initial core. Just have a separate core, so we needn't worry
about whether kernel_size and kernel_base are initialized.
* src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
kernel_size, kernel_items): Remove unnecessary initialization.
* src/conflicts.c (conflicts): Likewise.
* src/derives.c (derives): Likewise.
* src/muscle_tablc (muscle_insert): Likewise.
* src/relation.c (relation_digraph): Likewise.
* src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
conflrow, conflict_table, conflict_list, table, check):
Likewise.
* src/closure.c (new_closure): Arg is of type unsigned int, not int.
This is because all callers pass unsigned int.
* src/closure.h (new_closure): Likewise.
* src/lalr.c (initialize_F): Initialize reads[i] in all cases.
(build_relations): Initialize includes[i] in all cases.
* src/reader.c (packgram): Always initialize rules[ruleno].prec
and rules[ruleno].precsym. Initialize members in order.
* src/relation.c (relation_transpose): Always initialize new_R[i]
and end_R[i].
* src/table.c (conflict_row): Initialize 0 at end of conflict_list.
* src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
conflict_list[0] was always 0, but now it isn't initialized.
* src/table.c (table_grow): When conflict_table grew, the grown
area wasn't cleared. Fix this.
to allocate kernel_base, kernel_items, kernel_size, since
they needn't be initialized to 0.
(set_states): Don't reuse kernel_size and kernel_base
for initial core. Just have a separate core, so we needn't worry
about whether kernel_size and kernel_base are initialized.
(shift_symbol, redset, shiftset, kernel_base,
kernel_size, kernel_items): Remove unnecessary initialization.
GOTO_NUMBER_MAXIMUM, since we occasionally compute
ngotos + 1 without checking for overflow.
(build_relations): Use END_NODE, not -1, to denote end of edges.
(set_goto_map, map_goto, initialize_F, add_loopback_edge,
build_relations): Use goto_number, not int, for goto numbers.
* data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
of #defining from yystype.
Don't typedef yystype, C++ does not need it.
This lets it possible to forward declare it as union.
* data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
changes.
(YYCDEBUG): Adjust.
Use it instead of cdebug_.
(Parser::debug_stream, Parser::set_debug_stream): New.
(Parser::symprint_): Define cdebug_ for temporary backward
compatibility.
* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
debug_stream ().
Introduce another definition to address simple location arrays.
(yyGLRStack): New member: yyerror_range.
(yyrecoverSyntaxError, yyparse): Update it.
(yyrecoverSyntaxError): Use it when shifting the error token to
have an accurate range, equivalent to the one computed by both
yacc.c and lalr1.cc.
* tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
that column numbers start at column 0, as per GNU Coding
Standards, the others tests, and the doc.
(_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
Adjust to the above change (first column is 0).
And adjust the location of the "<error>", now covering the whole
line.
type names, destructors, and printers.
Reported by Alexandre Duret-Lutz.
Recode the handling of associativity and precedence in terms
of symbol_precedence_set.
Accept no redeclaration at all, not even equal to the previous
value.
(redeclaration): New.
Use it to factor redeclaration complaints.
(symbol_make_alias): Don't set the type of the alias, let
symbol_check_alias_consistency do it as for other features.
* src/symtab.h (symbol): Add new member prec_location, and
type_location.
* src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
* tests/input.at (Incompatible Aliases): New.
whether the reducion was empty or not. This leaves room to
improve the use of YYLLOC_DEFAULT in such a case.
lalr1.cc is still experimental, so changing this is acceptable.
And finally, there are probably not many users who changed the
handling of locations in GLR, so changing is admissible too.
* data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
empty reduction, set @$ to an empty location ending the previously
stacked symbol.
Adjust uses to make sure the code is triggered on empty
reductions.
* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
expected output: empty reductions have empty locations.
