Bison News
----------
Changes in version 2.3, 2006-06-05:
* GLR grammars should now use `YYRECOVERING ()' instead of `YYRECOVERING',
for compatibility with LALR(1) grammars.
* It is now documented that any definition of YYSTYPE or YYLTYPE should
be to a type name that does not contain parentheses or brackets.
Changes in version 2.2, 2006-05-19:
* The distribution terms for all Bison-generated parsers now permit
using the parsers in nonfree programs. Previously, this permission
was granted only for Bison-generated LALR(1) parsers in C.
* %name-prefix changes the namespace name in C++ outputs.
* The C++ parsers export their token_type.
* Bison now allows multiple %union declarations, and concatenates
their contents together.
* New warning: unused values
Right-hand side symbols whose values are not used are reported,
if the symbols have destructors. For instance:
exp: exp "?" exp ":" exp { $1 ? $1 : $3; }
| exp "+" exp
;
will trigger a warning about $$ and $5 in the first rule, and $3 in
the second ($1 is copied to $$ by the default rule). This example
most likely contains three errors, and could be rewritten as:
exp: exp "?" exp ":" exp
{ $$ = $1 ? $3 : $5; free ($1 ? $5 : $3); free ($1); }
| exp "+" exp
{ $$ = $1 ? $1 : $3; if ($1) free ($3); }
;
However, if the original actions were really intended, memory leaks
and all, the warnings can be suppressed by letting Bison believe the
values are used, e.g.:
exp: exp "?" exp ":" exp { $1 ? $1 : $3; (void) ($$, $5); }
| exp "+" exp { $$ = $1; (void) $3; }
;
If there are mid-rule actions, the warning is issued if no action
uses it. The following triggers no warning: $1 and $3 are used.
exp: exp { push ($1); } '+' exp { push ($3); sum (); };
The warning is intended to help catching lost values and memory leaks.
If a value is ignored, its associated memory typically is not reclaimed.
* %destructor vs. YYABORT, YYACCEPT, and YYERROR.
Destructors are now called when user code invokes YYABORT, YYACCEPT,
and YYERROR, for all objects on the stack, other than objects
corresponding to the right-hand side of the current rule.

Incorrect numbers of expected conflicts are now actual errors,
instead of warnings.
* GLR, YACC parsers.
The %parse-params are available in the destructors (and the
experimental printers) as per the documentation.
* Bison now warns if it finds a stray `$' or `@' in an action.
* %require "VERSION"
This specifies that the grammar file depends on features implemented
in Bison version VERSION or higher.
* lalr1.cc: The token and value types are now class members.
The tokens were defined as free form enums and cpp macros. YYSTYPE
was defined as a free form union. They are now class members:
tokens are enumerations of the `yy::parser::token' struct, and the
semantic values have the `yy::parser::semantic_type' type.
If you do not want or can update to this scheme, the directive
`%define "global_tokens_and_yystype" "1"' triggers the global
definition of tokens and YYSTYPE. This change is suitable both
for previous releases of Bison, and this one.
If you wish to update, then make sure older version of Bison will
fail using `%require "2.2"'.

Packaging hints for binary package distributors
===============================================
Although the source of the bison package comes as a single package,
in distributions of binary packages the installed files should
be split into two packages:
bison-runtime
Contents: Runtime libraries and programs.
Audience: Anyone who wants to run internationalized programs
that contain Bison-generated parsers.
bison
Contents: Tools and documentation for developers that use Bison.
Audience: Anyone who wants to develop programs that use parsers.
Dependencies: requires bison-runtime.
The 'bison-runtime' binary package is much smaller than the 'bison'
binary package. It should be included in any distribution that
contains localized programs that use the diagnostics contained in
Bison-generated parsers.
If you want to install both packages at the same time, you simply do
at the toplevel directory:
./configure
make
make install
After installation, the file
$prefix/share/locale/*/LC_MESSAGES/bison-runtime.mo
belongs to the bison-runtime package; all other installed files belong
to the bison package.

This is a test release of this package. Using it more or less
implicitly signs you up to help us find whatever problems you report.
The documentation still needs more work. Suggestions welcome.
Patches even more welcome.
Please send comments and problem reports about this test release to
[email protected]. This program will get better only if you report
the problems you encounter.
Please, *do not package this*, *do not distribute it* widely, it is
not ready for full scale use. Because it is not fully functional, if
you distribute this package, we will be buried under bug reports from
panicked users. We don't have time to spend on this, and nor do the

From phr Tue Jul 8 10:36:19 1986

From: phr (Paul Rubin)
To: riferguson%[email protected], tower
Subject: Re: Bison documentation?
The main difference between Bison and Yacc that I know of is that
Bison supports the @N construction, which gives you access to
the starting and ending line number and character number associated
with any of the symbols in the current rule.
Also, Bison supports the command `%expect N' which says not to mention
the conflicts if there are N shift/reduce conflicts and no reduce/reduce
conflicts.
The differences in the algorithms stem mainly from the horrible
kludges that Johnson had to perpetrate to make Yacc fit in a PDP-11.
Also, Bison uses a faster but less space-efficient encoding for the
parse tables (see Corbett's PhD thesis from Berkeley, "Static
Semantics in Compiler Error Recovery", June 1985, Report No. UCB/CSD
85/251), and more modern technique for generating the lookahead sets.
(See "Efficient Construction of LALR(1) Lookahead Sets" by F. DeRemer
and A. Pennello, in ACM TOPLS Vol 4 No 4, October 1982. Their
technique is the standard one now.)

it will be important for the various bits to define their needs in

# This skeleton produces a C++ class that encapsulates a C glr parser.
# This is in order to reduce the maintenance burden. The glr.c
# skeleton is clean and pure enough so that there are no real
# problems. The C++ interface is the same as that of lalr1.cc. In
# fact, glr.c can replace yacc.c without the user noticing any
# difference, and similarly for glr.cc replacing lalr1.cc.
#
# The passing of parse-params
#
# The additional arguments are stored as members of the parser
# object, yyparser. The C routines need to carry yyparser
# throughout the C parser; that easy: just let yyparser become an
# additional parse-param. But because the C++ skeleton needs to
# know the "real" original parse-param, we save them
# (b4_parse_param_orig). Note that b4_parse_param is overquoted
# (and c.m4 strips one level of quotes). This is a PITA, and
# explains why there are so many levels of quotes.
#
# The locations
#
# We use location.cc just like lalr1.cc, but because glr.c stores
# the locations in a (C++) union, the position and location classes
# must not have a constructor. Therefore, contrary to lalr1.cc, we
# must not define "b4_location_constructors". As a consequence the
# user must initialize the first positions (in particular the
# filename member).

Frequently Asked Questions about Bison:
----------------------------------------------------------------------
Q1. Is Bison Y2K compliant?
A1. If you're looking for a guarantee or certification, I can't
provide it. With a little thought you can answer this one for
yourself, though. (Hint: does a parser generator rely on the
date or time for anything?) If you're still confused, see
http://www.gnu.org/software/year2000.html for more information.
----------------------------------------------------------------------
Q2. I can't build Bison because "make" complains that "msgfmt" is not
found. What should I do?
A2. Like most GNU packages with internationalization support, that
feature is turned on by default. If you have problems building
in the "po" subdirectory, it indicates that your system's
internationalization support is lacking. You can re-configure
Bison with "--disable-nls" to turn off this support, or you can
install GNU gettext from ftp://ftp.gnu.org/gnu/gettext/ and
re-configure Bison. See the file "ABOUT-NLS" for more
information.
----------------------------------------------------------------------
Q3. I'm having trouble using Bison. Where can I find help?
A3. First, read the fine manual which comes with bison. Beyond that,
you can send mail to <[email protected]>. This mailing list is
intended to be populated with people who are willing to answer
questions about using and installing Bison. Please keep in mind
that (most of) the people on the list have aspects of their lives
which are not related to Bison (!), so you may not receive an
answer to your question right away. This can be frustrating, but
please try not to honk them off; remember that any help they
provide is purely voluntary and out of the kindness of their
hearts.
----------------------------------------------------------------------
Q4. I found a bug. What should I include in the bug report?
A4. Before you send a bug report, make sure you are using the latest
version. Check ftp://ftp.gnu.org/pub/gnu/bison/ or one of its
mirrors. Be sure to include the version number in your bug
report. If the bug is present in the latest version but not in a
previous version, try to determine the most recent version which
did not contain the bug.
If the bug is parser-related, you should include the smallest
grammar you can which demonstrates the bug. The grammar file
should also be complete (i.e., I should be able to run it through
Bison without having to edit or add anything). The smaller and
simpler the grammar, the easier it will be to fix the bug.
Include information about your compilation environment, including
your operating system's name and version and your compiler's name
and version. If you have trouble compiling, you should also
include a transcript of the build session, starting with the
invocation of `configure'. Depending on the nature of the bug,
you may be asked to send additional files as well (such as
`config.h' or `config.cache').
Patches are most welcome, but not required. That is, do not
hesitate to send a bug report just because you can not provide a
fix.
Send bug reports to <[email protected]>.
----------------------------------------------------------------------
Q5. Will Bison ever have C++ support?
A5. Yes, it's in the works. Things are very chaotic right now, but
what little information floats around is posted to the bug-bison
mailing list. If you're interested in testing C++ support when
it becomes available, please consider subscribing to the list,
especially if you are willing to beta test other releases as
well.
----------------------------------------------------------------------
Q6. What is involved in being a beta tester?
A6. It's not terribly involved. Basically, you would download a test
release, compile it, and use it to build and run a parser or two.
After that, you would submit either a bug report or a message
saying that everything is okay. It is important to report
successes as well as failures because test releases eventually
become mainstream releases, but only if they are adequately
tested. If no one tests, development is essentially halted.
Beta testers are particularly needed for operating systems to
which I do not have access. I currently have easy access to
Linux (x86 glibc 2.1), Solaris (SPARC) 2.6 and 2.7, and HP-UX
10.20. Reports about other operating systems are especially
welcome.
----------------------------------------------------------------------
Q7. How do I join the help-bison and bug-bison mailing lists?
A7. See http://www.gnu.org/ (the section about "GNU mailing lists")
for more information.

/* alloca.c -- allocate automatically reclaimed memory
(Mostly) portable public-domain implementation -- D A Gwyn
This implementation of the PWB library alloca function,
which is used to allocate space off the run-time stack so
that it is automatically reclaimed upon procedure exit,
was inspired by discussions with J. Q. Johnson of Cornell.
J.Otto Tennant <jot@cray.com> contributed the Cray support.
There are some preprocessor constants that can
be defined when compiling for your specific system, for
improved efficiency; however, the defaults should be okay.
The general concept of this implementation is to keep
track of all alloca-allocated blocks, and reclaim any
that are found to be deeper in the stack than the current
invocation. This heuristic does not reclaim storage as
soon as it becomes invalid, but it will do so eventually.
As a special case, alloca(0) reclaims storage without
allocating any. It is a good idea to use alloca(0) in
your main control loop, etc. to force garbage collection. */

#ifndef VERIFY_H
# define VERIFY_H 1
/* Each of these macros verifies that its argument R is nonzero. To
be portable, R should be an integer constant expression. Unlike
assert (R), there is no run-time overhead.
There are two macros, since no single macro can be used in all
contexts in C. verify_true (R) is for scalar contexts, including
integer constant expression contexts. verify (R) is for declaration
contexts, e.g., the top level.
Symbols ending in "__" are private to this header.
The code below uses several ideas.
* The first step is ((R) ? 1 : -1). Given an expression R, of
integral or boolean or floating-point type, this yields an
expression of integral type, whose value is later verified to be
constant and nonnegative.
* Next this expression W is wrapped in a type
struct verify_type__ { unsigned int verify_error_if_negative_size__: W; }.
If W is negative, this yields a compile-time error. No compiler can
deal with a bit-field of negative size.
One might think that an array size check would have the same
effect, that is, that the type struct { unsigned int dummy[W]; }
would work as well. However, inside a function, some compilers
(such as C++ compilers and GNU C) allow local parameters and
variables inside array size expressions. With these compilers,
an array size check would not properly diagnose this misuse of
the verify macro:
void function (int n) { verify (n < 0); }
* For the verify macro, the struct verify_type__ will need to
somehow be embedded into a declaration. To be portable, this
declaration must declare an object, a constant, a function, or a
typedef name. If the declared entity uses the type directly,
such as in
struct dummy {...};
typedef struct {...} dummy;
extern struct {...} *dummy;
extern void dummy (struct {...} *);
extern struct {...} *dummy (void);
two uses of the verify macro would yield colliding declarations
if the entity names are not disambiguated. A workaround is to
attach the current line number to the entity name:
#define GL_CONCAT0(x, y) x##y
#define GL_CONCAT(x, y) GL_CONCAT0 (x, y)
extern struct {...} * GL_CONCAT(dummy,__LINE__);
But this has the problem that two invocations of verify from
within the same macro would collide, since the __LINE__ value
would be the same for both invocations.
A solution is to use the sizeof operator. It yields a number,
getting rid of the identity of the type. Declarations like
extern int dummy [sizeof (struct {...})];
extern void dummy (int [sizeof (struct {...})]);
extern int (*dummy (void)) [sizeof (struct {...})];
can be repeated.
* Should the implementation use a named struct or an unnamed struct?
Which of the following alternatives can be used?
extern int dummy [sizeof (struct {...})];
extern int dummy [sizeof (struct verify_type__ {...})];
extern void dummy (int [sizeof (struct {...})]);
extern void dummy (int [sizeof (struct verify_type__ {...})]);
extern int (*dummy (void)) [sizeof (struct {...})];
extern int (*dummy (void)) [sizeof (struct verify_type__ {...})];
In the second and sixth case, the struct type is exported to the
outer scope; two such declarations therefore collide. GCC warns
about the first, third, and fourth cases. So the only remaining
possibility is the fifth case:
extern int (*dummy (void)) [sizeof (struct {...})];
* This implementation exploits the fact that GCC does not warn about
the last declaration mentioned above. If a future version of GCC
introduces a warning for this, the problem could be worked around
by using code specialized to GCC, e.g.,:
#if 4 <= __GNUC__
# define verify(R) \
extern int (* verify_function__ (void)) \
[__builtin_constant_p (R) && (R) ? 1 : -1]
#endif
* In C++, any struct definition inside sizeof is invalid.
Use a template type to work around the problem. */
/* Verify requirement R at compile-time, as an integer constant expression.
Return 1. */
# ifdef __cplusplus
template <int w>
struct verify_type__ { unsigned int verify_error_if_negative_size__: w; };

# else
# define verify_true(R) \

trailing ';'. */
