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.
top of the location stack's error locations.
(yyerrlab): Set it. When discarding a token, push its location
onto yylerrsp so that we don't lose track of the error's end.
(yyerrlab1): Now is only the target of YYERROR, so that we can
properly record the location of the action that failed. For GCC
2.93 and later, insert an __attribute__ ((__unused__)) to avoid
GCC warning about yyerrlab1 being unused if YYERROR is unused.
(yyerrlab2): New label, which yyerrlab now falls through to.
Compute the error's location by applying YYLLOC_DEFAULT to
the locations of all the symbols that went into the error.
Remove obsolete references to bison.simple and bison.hairy.
* src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL.
* src/parse-gram.y (declaration): Use enum "report_states".
* src/scan-skel.l ("@output ".*\n): Close any old yyout before new one.
using typedef instead of defining it as a macro. POSIX requires this.
For consistency, YYLTYPE is also declared instead of defined.
%union directives can now have a tag before the `{', e.g., the
directive `%union foo {...}' now generates the C code
`typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
The default union tag is `YYSTYPE', for compatibility with Solaris 9
Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
instead of `yyltype'.
`yystype' and `yyltype' are now obsolescent macros instead of being
typedefs or tags; they are no longer documented and will be
withdrawn in a future release.
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.
