Renamed from conflict_report_yacc, removing the old
'conflict_report'. Translate the entire conflict report at once,
so that we don't assume that "," has the same interpretation in
all languages.
(conflicts_output): Use Yacc-style conflict report for each state,
instead of our more-complicated style.
(conflicts_print): Use Yacc-style conflict report, except print
the input file name when not emulating Yacc.
token_type, not braced_code code_kind. All uses changed.
(SC_PRE_CODE): New state, for scanning after a keyword that
has (or usually has) an immediately-following braced code.
(token_type): New local var, to keep track of which token type
to return when scanning braced code.
(<INITIAL>"%destructor", <INITIAL>"%lex-param",
<INITIAL>"%parse-param", <INITIAL>"%printer,
<INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
instead of returning a token type immediately.
(<INITIAL>"{"): Set token type.
(<SC_BRACED_CODE>"}"): Use it.
(handle_action_dollar, handle_action_at): Now returns bool
indicating success. Fail if ! current_rule; this prevents a core dump.
(handle_symbol_code_dollar, handle_symbol_code_at):
Remove; merge body into caller.
(handle_dollar, handle_at): Complain in invalid contexts.
const *, since it is now modified by stripping surrounding { }.
(current_braced_code): Remove.
(PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
trailing " {...}". Now of type <chars>.
(grammar_declaration): Adjust to bundled tokens.
(code_content): Remove; stripping is now done by add_param.
(print_token_value): Print contents of bundled tokens.
(token_name): New function.
(uniqstr_print_processor): New function, to avoid casts.
(uniqstrs_new, hash_initialize, uniqstrs_do):
Use new functions instead of casting old functions unportably.
(hash_compare_uniqstr): Remove unnecessary casts.
symbol_number_to_vector_number):
Now inline functions rather than macros, to avoid casts.
(table_size): Now int, to pacify GCC.
(table_grow, table_ninf_remap): Use signed table size.
(save_row): Don't bother initializing locals when not needed.
(default_goto, goto_actions, pack_vector): Remove unnecessary casts.
(<stddef.h>): Include, for offsetof.
(<inttypes.>, <stdint.h>): Include if available.
(uintptr_t): New type, if system lacks it.
(CALLOC, MALLOC, REALLOC): New macros.
All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
new macros.
symbol_check_alias_consistency, symbol_pack, symbol_translation,
hash_compare_symbol, hash_symbol):
Now inline. Return bool, not int.
(symbol_check_defined_processor,
symbol_check_alias_consistency_processor, symbol_pack_processor,
symbol_translation_processor, hash_symbol_comparator,
hash_symbol_hasher): New functions, to avoid casts.
(symbols_new, symbols_do, symbols_check_defined,
symbols_token_translations_init):
Use new functions instead of casting old functions unportably.
(symbol_free): Remove; unused.
(symbol_get): Remove cast in lhs of assignment.
(symbols_do): Now static. Accept generic arguments, not hashing-related ones.
(state_comparator, stage_hasher): New function, to avoid casts.
(state_hash_new): Use new functions instead of casting old functions unportably.
(state_hash_lookup): Use MALLOC rather than alloca, so that we don't
have to worry about alloca.
(TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
STATE_ALLOC): Remove.
(transitions_new, errs_new, reductions_new, state_new): Use malloc
rather than calloc, and use offsetof to avoid allocating slightly
too much storage.
(state_new): Initialize all members.
(state_hash): Use unsigned accumulator, not signed.
item_number_as_symbol_number, rule_number_as_item_number,
item_number_as_rule_number): Now inline functions rather
than macros, to avoid casts.
(int_of_rule_number): Remove; no longer used.
the pointer DSET returned by malloc; this isn't portable.
Instead, always use DSET[i - NTOKENS] rather than DSET[i].
Similarly for DERIVES.
(derives_compute): Do not bother invoking
int_of_rule_number, since rule numbers are integers.
All uses of XCALLOC, XMALLOC, and XREALLOC changed to use new macros
CALLOC, MALLOC, REALLOC. All uses of XFREE changed to free.
