This patch contains more fixes to prefer signed to unsigned integer types, as modern tools like 'gcc -fsanitize=undefined' can check for signed integer overflow but not unsigned overflow. * NEWS: Document the API change. * boostrap.conf (gnulib_modules): Add intprops. * data/skeletons/glr.c: Include stddef.h and stdint.h, since this skeleton can assume C99 or later. (YYSIZEMAX): Now signed, and the minimum of SIZE_MAX and PTRDIFF_MAX. (yybool) [!__cplusplus]: Now signed (which is how bool behaves). (YYTRANSLATE): Avoid use of unsigned, and make the macro safe even for values greater than UINT_MAX. (yytnamerr, struct yyGLRState, struct yyGLRStateSet, struct yyGLRStack) (yyaddDeferredAction, yyinitStateSet, yyinitGLRStack) (yyexpandGLRStack, yymarkStackDeleted, yyremoveDeletes) (yyglrShift, yyglrShiftDefer, yy_reduce_print, yydoAction) (yyglrReduce, yysplitStack, yyreportTree, yycompressStack) (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError) (yyparse, yy_yypstack, yypstack, yypdumpstack): * tests/input.at (Torturing the Scanner): Prefer ptrdiff_t to size_t. * data/skeletons/c++.m4 (b4_yytranslate_define): * src/AnnotationList.c (AnnotationList__computePredecessorAnnotations): * src/AnnotationList.h (AnnotationIndex): * src/InadequacyList.h (InadequacyListNodeCount): * src/closure.c (closure_new): * src/complain.c (error_message, complains, complain_indent) (complain_args, duplicate_directive, duplicate_rule_directive): * src/gram.c (nritems, ritem_print, grammar_dump): * src/ielr.c (ielr_compute_ritem_sees_lookahead_set) (ielr_item_has_lookahead, ielr_compute_annotation_lists) (ielr_compute_lookaheads): * src/location.c (columns, boundary_print, location_print): * src/muscle-tab.c (muscle_percent_define_insert) (muscle_percent_define_check_values): * src/output.c (prepare_rules, prepare_actions): * src/parse-gram.y (id, handle_require): * src/reader.c (record_merge_function_type, packgram): * src/reduce.c (nuseless_productions, nuseless_nonterminals) (inaccessable_symbols): * src/relation.c (relation_print): * src/scan-code.l (variant, variant_table_size, variant_count) (variant_add, get_at_spec, show_sub_message, show_sub_messages) (parse_ref): * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>) (scan_integer, convert_ucn_to_byte, handle_syncline): * src/scan-skel.l (at_complain): * src/symtab.c (complain_symbol_redeclared) (complain_semantic_type_redeclared, complain_class_redeclared) (symbol_class_set, complain_user_token_number_redeclared): * src/tables.c (conflict_tos, conflrow, conflict_table) (conflict_list, save_row, pack_vector): * tests/local.at (AT_YYLEX_DEFINE(c)): Prefer signed to unsigned integer. * data/skeletons/lalr1.cc (yy_lac_check_): * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): * tests/local.at (AT_YYLEX_DEFINE(c)): Omit now-unnecessary casts. * data/skeletons/location.cc (b4_location_define): * doc/bison.texi (Mfcalc Lexer, C++ position, C++ location): Prefer int to unsigned for line and column numbers. Change example to abort explicitly on memory exhaustion, and fix an off-by-one bug that led to undefined behavior. * data/skeletons/stack.hh (stack::operator[]): Also allow ptrdiff_t indexes. (stack::pop, slice::slice, slice::operator[]): Index arg is now ptrdiff_t, not int. (stack::ssize): New method. (slice::range_): Now ptrdiff_t, not int. * data/skeletons/yacc.c (b4_state_num_type): Remove. All uses replaced by b4_int_type. (YY_CONVERT_INT_BEGIN, YY_CONVERT_INT_END): New macros. (yylac, yyparse): Use them around conversions that -Wconversion would give false alarms about. Omit unnecessary casts. (yy_stack_print): Use int rather than unsigned, and omit a cast that doesn’t seem to be needed here any more. * examples/c++/variant.yy (yylex): * examples/c++/variant-11.yy (yylex): Omit no-longer-needed conversions to unsigned. * src/InadequacyList.c (InadequacyList__new_conflict): Don’t assume *node_count is unsigned. * src/output.c (muscle_insert_unsigned_table): Remove; no longer used.
