scan-code.l is already passing argument to b4_dollar_dollar for the
initial acton, but its definition (of b4_dollar_dollar) does not use
this argument.
Generalize this definition, and use it for the %initial-action too.
* data/c.m4 (b4_dollar_dollar_, b4_dollar_pushdef, b4_dollar_popdef):
Instead of expecting a pointer, require a value, and use ".".
Since they are now generic enough, move to...
* data/c-like.m4: this new file.
* data/c.m4, data/java.m4: Load it.
* data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c: Use
b4_dollar_pushdef for the %initial-action.
* tests/actions.at: Check that.
* data/Makefile.am: Adjust.
* NEWS, doc/bison.texi: Document.
Currently "%printer {...} a b c d e f" translates the {...} six times.
Not only is this bad for time and space, it also issues six times the
same warnings.
* src/symlist.h, src/symlist.c (symbol_list_destructor_set)
(symbol_list_printer_set): Take the action as code_props instead of
const char *.
* src/parse-gram.y: Translate these actions here.
* src/scan-code.h: Comment change.
* tests/input.at: Check that warnings are issued only once.
The conversion from @ to @@ and so forth is coded is too many
different places. Factor, a bit.
* src/scan-code.l: Instead of duplicating the logic of obstack_escape,
use it.
It sure is less efficient, but the cost is negligible.
This allows to factor rules that are alike.
And to factor some start-condition clauses.
* tests/input.at (Stray $ or @): New.
* NEWS: Document it.
* src/scan-code.l, src/scan-skel.l: Use a more traditional indentation
style for start-conditions.
Prefer "continue" to a comment, for empty actions.
Strip useless {}.
Remove useless start-condition clauses.
* src/scan-code.l (SC_SYMBOL_ACTION): Accept $<tag>$, not just $$.
* data/c.m4 (b4_dollar_dollar_): New.
(b4_symbol_actions): Let b4_dollar_dollar use b4_dollar_dollar_.
* NEWS, doc/bison.texi: Document it.
* tests/actions.at: Check this for C and C++.
muscles: fix another occurrence of unescaped type name
* src/output.c (quoted_output): Split into...
(quoted_output, string_output): these.
Use the former when outputting a type_name.
* tests/input.at: Check this case.
* src/symtab.h: Comment changes.
* src/scan-code.l: Use obstack_quote when passing type_name to m4.
* tests/input.at (Code injection): New.
* NEWS: Document it.
Thanks to Paul Eggert for the wording.
* src/system.h (obstack_quote): New.
* src/muscle-tab.c: Use it instead of obstack_escape where applicable.
* src/scan-code.l: Since obstack_quote supports NULL, leave type_name
as NULL instead of defaulting to "".
* src/muscle-tab.c (MUSCLE_COMMON_DECODE, muscle_string_decode)
(muscle_location_decode): Not related to muscles, rename as...
(COMMON_DECODE, string_decode, location_decode): these.
* src/muscle-tab.h (MUSCLE_OBSTACK_SGROW): This is not related to
muscles, so move to, and rename as...
* src/system.h (obstack_escape): this.
Adjust dependencies.
doc: avoid problems with case insensitive file systems
makeinfo --html generates index.html, and the node "Index" will result
in Index.html. On case insensitive file systems, such as on Mac OS X
by default, this results in a single, invalid, file (Texinfo 4.13).
See http://lists.gnu.org/archive/html/bug-texinfo/2012-07/msg00032.html
* doc/bison.texi (Index): Rename as...
(Index of Terms): this.
* configure.ac: In the AC_SUBST call on 'VALGRIND_PREBISON'. Without
this change, when running ./configure, I see:
...
checking for valgrind... valgrind
./configure: line 35221: -q: command not found
checking for Java compiler... gcj -C -fsource=1.3 -ftarget=1.4
...
Currently they are treated in separated variables, contrary to other
<TYPE> code_props. This duplicates code (and messages for translators)
uselessly, as demonstrated by the fact that thanks to this patch, now
useless <*> and <> code_props are reported like the others.
* src/parse-gram.y (generic_symlist_item): Treat "<*>" and "<>" as regular
type tags.
* src/symlist.h, src/symlist.c (symbol_list_default_tagged_new)
(symbol_list_default_tagless_new,SYMLIST_DEFAULT_TAGGED)
(SYMLIST_DEFAULT_TAGLESS): Remove.
* src/symtab.h, src/symtab.c (default_tagged_code_props)
(default_tagless_code_props, default_tagged_code_props_set)
(default_tagless_code_props_set): Remove.
(symbol_code_props_get): Default to <*> or <>'s code_props.
* tests/actions.at: Complete expected errors: there are new warnings.
* tests/input.at: Likewise.
(Useless printers or destructors): Extend.
The logic to compute the %printer or %destructor to used (i.e., a
code_props) is implemented twice: one, of course, in
symbol_code_props_get, and another time in symbol_check_defined to
record the fact that a code_props is used (so that we can reported
unused ones). Let the former use the latter.
I would probably use "mutable" in C++ and keep these guys const,
but this is C. And casting away constness triggers warnings.
* src/scan-code.h, src/scan-code.l (code_props_none): Is not const.
* src/symtab.h, src/symtab.c (symbol_code_props_get): The symbol
is not const.
(symbol_check_defined): Use it.
Because I'm using a VPATH build with an absolute srcdir, I have
GRAM__USERS_AKIM_SRC_GNU_BISON_SRC_PARSE_GRAM_H. Before, I was using
a relative srcdir, and had GRAM_______SRC_PARSE_GRAM_H (coming from
../../). Let it be GRAM_SRC_PARSE_GRAM_H.
* tests/bison.in: Do not depend on the value of $top_srcdir for
Bison itself.
If we were to use relative paths from .c to .y, we would not have
this problem.
* data/glr.c, data/glr.cc, data/lalr1.cc, data/lalr1.java, data/yacc.c:
Since the previous commit, b4_tokens_define and the like no longer need
b4_tokens.
* src/output.c (token_definitions_output): Remove.
output: use the token list to define the yytokentype
There are currently two systems used to pass information about tokens to
m4: the original one, and another, which is used for instance for
printers and destructors, variants etc. Move to using only the latter.
* data/bison.m4 (b4_symbol_map, b4_token_visible_if)
(b4_token_has_definition, b4_any_token_visible_if, b4_token_format): New.
* data/c++.m4, data/c.m4, data/glr.c, data/java.m4: Adjust to use them.
* origin/maint:

since, of course YYSTYPE_IS_TRIVIAL is defined. Instead we could
define YYSTYPE_IS_TRIVIAL as PREFIX_STYPE_IS_TRIVIAL only when the
later is defined, but let's avoid stacking CPP on top of M4: rather, use
* data/glr.c, data/yacc.c: Use YYSTYPE_IS_TRIVIAL, YYSTYPE_IS_DECLARED,
YYLTYPE_IS_TRIVIAL and YYLTYPE_IS_DECLARED under their api.prefix-renamed
name.
The testsuite in master has shown weird errors for the "Mulitple
Parsers" tests: the caller of p5.parse() received some apparently
random value, while tracing p5.parse() showed that the function was
consistently returning 0.
It happens when mixing several parser headers, some generated without
%debug, others with. In particular the C++ parser was generated with
%debug, i.e., with:
#ifndef YYDEBUG
# define YYDEBUG 1
#endif
and compiled separatedly. Yet, its header was included after the one
of another parser, this time without %debug, i.e., with
#ifndef YYDEBUG
# define YYDEBUG 0
#endif
in its header. As a result, the parser was compiled with YYDEBUG set,
but its header was used without. Since the layout of the objects are
then completely different, boom.
Therefore, do not change the value of YYDEBUG. Rather, use it as a
default value for <API.PREFIX>DEBUG.
* data/c.m4 (b4_YYDEBUG_define): New.
(b4_declare_yydebug): Rename as...
(b4_yydebug_declare): this, for consistency.
* data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c: Use it.
