omitted an adjustment of the #line value used for code-file. Fix that.

YYPATCH #define's to make test-outputs easier to compare #line's (report
by Tom Shields)
2014-04-06 Thomas E. Dickey <tom@invisible-island.net>
* reader.c: fix for valgrind
(the calloc's are intentional - valgrind reported use of uninitialized memory)

add rules to generate byacc and btyacc parser skeleton files independently
* aclocal.m4: CF_PROG_AWK - add to byacc's configure script

protect $2 from substitution, for luit's "$(manext)"
CF_XOPEN_SOURCE
for Solaris (tested with gcc/g++ 3.4.3 on Solaris 10 and gcc/g++ 4.5.2
on Solaris 11), suppress the followup check for defining _XOPEN_SOURCE
because it is not needed, as well as because g++ 4.7.3 (no package,
used in Sage for Solaris 10) has some unspecified header breakage which
is triggered by the duplicate definition.

modify so skeleton-source is determined by configure options rather than by
having developer rename yaccpar.skel.old to yaccpar.skel

more merging of Tom Shield's btyacc changes. In the merge, I moved the
symbol_pval inside the btyacc ifdef's and added some more btyacc ifdefs
2014-04-03 Thomas E. Dickey <tom@invisible-island.net>

merge-in 3/4 of btyacc's changes, deferring those which change test-outputs.
Tom Shield's changes split-out copy_string() and copy_comment() functions
to simplify some logic, as well as adding btyacc-only chunks
* makefile.in: build mstring.o, needed for changes in reader.c
* output.c:
merge-in all of btyacc's changes which do not change byacc's test-output.
Some of the merge uses ifdef-changes which I applied to ongoing resync,
e.g., the introduction of PER_STATE.

modified new options to act like those in my other configure-scripts, e.g.,
showing what option is being tested, and the resulting value. Put the
definitions in config.h rather than in the makefile.

PARKING LOT ISSUES:
-------------------
- verify debian packaging still works?
- there are no #line directives in y.tab.i, other than those that come
from the input file and the skeleton file; to fix this, would need to
count output lines in externs_file and add 'write_externs_lineno()'
similar to 'write_code_lineno()'
- if there are no defined symbols, the .tab.h file isn't empty (weird case,
may not be worth fixing)
- consider: treat []-actions identical to {}-actions if not processing a
backtracking parser (avoids test case error)?
BTYACC CHANGES CURRENTLY DEFERRED, BY FILE:

- adopt '%include' changes
- adopt '%define'/'%ifdef'/'%endif'
- adopt -E flag to print preprocessed grammar to stdout

================================================================================
new files:
----------
skel2c
- modified from btyacc distribution: don't generate #include defs.h
- extended syntax recognized to include '%% insert VERSION here', generating
the defines for YYMAJOR, YYMINOR and YYPATCH at that point
- made generated tables type 'const char *const' to match skelton.c from
byacc-20130925 baseline
- added code to append text for write_section() to end of generated skeleton.c
- remove conversion of tab to \t in generated skeleton.c
- extended syntax recognized to include '%%ifdef', '%%ifndef', '%%else' and
'%%endif'; used in yaccpar.skel to bracket code that is specific to
backtracking
yaccpar.skel.old
- created from skeleton.c in byacc-20140101 baseline; use of this skeleton
will create a version of skeleton.c that is close to that in the
byacc-20140101 baseline
- eliminated 'body_3' and 'trailer_2' skeleton segments - no need to generate
yyerror() invocation dynamically; YYERROR_CALL() is already generated
earlier, and so can be used in the skeleton to simplify
- added 'const' to types in '%% tables' section to match what skel2c,
start_int_table() and state_str_table() generate
- added a few cosmetic changes (e.g., added some additional comments,
reworded debugging output to match yaccpar.skel, changed yygrowstack()
to return YYENOMEM for 'out of memory' error, rather than -1, to match
yaccpar.skel; changed yyparse() return value from 1 to 2 for the
'out of memory' error to match yaccpar.skel)
- added '#ifndef'/'#endif' around '#define YYINITSTACKSIZE 200' to allow
the value to be changed at compile time
- changed 'printf(' to 'fprintf(stderr, '; added stack depth (yydepth) to
debugging output from yaccpar.skel
- use 'YYINT' rather than 'short' for integer table types
yaccpar.skel
- renamed from btyaccpa.ske, merged with btyacc-c.ske
- modified from btyacc distribution to match the latest byacc-20140101
skeleton structure & data structures
- make local functions static
- change "virtual memory exceeded" to "memory exhausted" for bison
compatibility
- change debug output generation from printf/puts/putc onto stdout to use
fprintf/fputs/fputc onto stderr; include
stack depth and whether or not in trial parsing
- changed types of generated string tables to be 'const pointer to const char'
- check all malloc()/realloc() return values, ensure return value of
yyparse() = 2 if parsing failed due to memory exhaustion
- change YYDBPR() macro to YYSTYPE_TOSTRING(); define semantics as delivering
a char* value representing a semantic value (e.g., yylval or yyval, or the
contents of an entry on the semantic stack); additional parameter passed:
grammar symbol # (to assist interpretation of semantic value)
- change YYPOSN to YYLTYPE and yyposn to yylloc (position corresponding to
yylval) for bison compatibility; add yyloc (corresponding to yyval)
- move default definition of YYLTYPE into output.c, generating a typedef
- add '#if defined(YYLTYPE) || defined(YYLTYPE_IS_DECLARED)'/'#endif' around
all lines specific to position processing
- add '#if defined(YYDESTRUCT_CALL)'/'#endif' around all lines specific to
semantic & position stack processing to reclaim memory associated with
discarded symbols
- add '%%ifdef YYBTYACC'/'%%endif' around all lines specific to backtrack
parsing; converted by skel2c into '#if defined(YYBTYACC)'/'#endif'
- distinguish between "yacc stack overflow" and "memory exhausted" situations
- consolidated termination cleanup code; introduced yyreturn, set to 2 after
labels yyoverflow/yyenomem, set to 1 after label yyabort, set to 0 after
label yyaccept; all termination cases jump to label yyreturn, which does
any cleanup then returns yyreturn value
- replaced YYDELETEVAL & YYDELETEPOSN user-supplied macro capability by
implementation of byacc-generated yydestruct() as defined by bison
compatible %destructor mechanism
- moved invocation of 'YYREDUCEPOSNFUNC' macro to immediately prior to, rather
than after, execution of final rule action (so that, at some future
date, implementation extensions can be added to enable custom calculation
of locations associated with non-terminals within rule actions); deleted
unnecessary flag 'reduce_posn'; deleted 'YYCALLREDUCEPOSN' macro; deleted
C++ variant of 'YYREDUCEPOSNFUNC' invocation
- adopt approach similar to bison for default computation of yyloc; change
macro 'YYREDUCEPOSNFUNC' name to 'YYLLOC_DEFAULT' for bison compatibility;
added 'yyerror_loc_range[2]' to hold start & end locations for error
situations that pop the stack
- use 'YYINT' rather than 'short' for integer table types, and for indexing
parser tables
readskel.c
http://www.verisign.com/index.html- replaced error() with fprintf()
mstring.h
- moved contents of mstring.h to defs.h - mstring.h is obsolete
mstring.c
- replaced include of mstring.h with defs.h
- changed 'START' to 'HEAD' to remove conflict with 'START' used for
the start symbol defined in defs.h
modified byacc files:
---------------------
skeleton.c
- skeleton.c is now generated from the appropriate skeleton file by 'skel2c'
configure.in
- added configuration for --enable-btyacc option; if 'yes' add '-DYYBTYACC'
to DEFINES in makefile.in; --enable-btyacc defaults to 'no'
- added configuration for --with-max-table-size option; if present,
overrides the value of MAXTABLE defined in defs.h
- regenerate configure using autoconf
makefile.in
- added mstring.c to C_FILES
- added mstring$o to OBJS
- added @DEFINES@ as value of DEFINES make variable
- added new make variable SKELETON with value 'yaccpar.skel'
- added rule to generate skeleton.c from $(SKELETON), depending on skel2c
and makefile
- added rm -f skeleton.c distclean rule
- moved dependency on makefile from only main$o & skeleton$o to $(OBJS),
since if ./configure is run changing, for example, from --enable-btyacc
to --disable-btyacc, all files must be recompiled to ensure a clean
executable
- add @MAXTABLE@ for optional '-DMAXTABLE=nnn' if configured using
--with-max-table-size=nnn
- changed 'cd test && rn 0f test-*'to 'rm -f $(testdir)/test-*'
test/run_test.sh
- ???
test/run_make.sh
- ???
defs.h
- moved contents of mstring.h to defs.h - mstring.h is obsolete
- added <limits.h> to get the various system defined machine limits;
changed definitions of MAXCHAR, MAXSHORT, MINSHORT & BITS_PER_WORD to use
defines from <limits.h>; changed definitions of BIT and SETBIT to use
value of BITS_PER_WORD
- added typedef for __compar_fn_t, conditioned on _COMPAR_FN_T being
undefined (at least for Mac OSX environment)
- adopt new symbol class values ACTION and ARGUMENT
- adopt changes/additions used by inherited attribute processing
- clean up locations of extern function definitions to match where they
actually live in source files

- added extern decl for 'int locations'; true if %locations present
- added extern decl for 'int backtrack'; initialized to 0 (= false), set to
1 (= true) if -B flag is present
- added extern decl for 'int destructor'; true if at least one %destructor
present in grammar spec file
- define 'YYINT' as the smallest C type that can be used to address a
table of size 'MAXTABLE'; define 'YYINT' based on the value of
'MAXTABLE' using the standard system type size definitions from <limits.h>;
define 'MAXYYINT' and 'MINYYINT' accordingly
- change 'Value_t' and 'Index_t' to 'YYINT' from 'short'
- allow 'MAXTABLE' to be defined by '-DMAXTABLE=nnn' at compile-time
closure.c
- changed print_closure(), print_EFF() and print_first_derives() to 'static';
added fwd declarations
- changed 'short' to 'Value_t' (in some instances, 'Value_t' was already
used for variables/parameters that were related to variables/parameters
declared as 'short'
error.c
- adopt error functions from inherited attribute processing; added a few
additional inherited attribute error functions
graph.c
- changed 'short' to 'Value_t' (in some instances, 'Value_t' was already
used for variables/parameters that were related to variables/parameters
declared as 'short'
lalr.c
- changed MAXSHORT to MAXYYINT
lr0.c
- changed MAXSHORT to MAXYYINT
- changed 'short' to 'Value_t' (in some instances, 'Value_t' was already
used for variables/parameters that were related to variables/parameters

main.c
- changed 'short' to 'Value_t' (in some instances, 'Value_t' was already
used for variables/parameters that were related to variables/parameters
declared as 'short'
mkpar.c
- backtracking attempts to resolve shift/reduce and reduce/reduce conflicts
output.c
- generate prefix & YYPREFIX defines into externs file (-i, .tab.i) and
code file (-r, .code.c); generate into output file (.tab.c) only if not
using -r option; eliminates doubled output of prefix aliases if -r with
no -i in y.tab.c and y.code.c or if -r & -i in y.tab.i and y.code.c
- changed types of generated string tables to be 'const pointer to const char'
- adopt backtracking as an alternative in cases where otherwise we have a
conflict in the parsing actions (3, rather than 2, choices)
- wrap defines file with (where "yy" is value of 'symbol_prefix')
#ifndef __yy_defines_h_
#define _yy_defines_h_
<defines>
#endif
- avoid writing %%xdecls skeleton section twice if -r used
- eliminated 'body_3' and 'trailer_2' skeleton segments - no need to generate
yyerror() invocation dynamically; YYERROR_CALL() is already generated
earlier, and can be used in the pareser skeleton
- if -P flag (pure_parser), add yylloc as 2nd parameter to yylex()
(declaration & call)
- change YYPOSN to YYLTYPE and yyposn to yylloc (position corresponding to
yylval) for bison compatibility; add yyloc (corresponding to yyval)
- generate yylloc parameters for yylex & yyerror if %locations present
- add location as 1st parameter to declaraion & invocation of yyerror() if
%locations present
- output backtrack parsing tables if -B flag is present
- added generation of yystos[] with output_accessing_symbols() to allow
translation from a parser internal state number to the corresponding
grammar symbol number [0 .. nsyms) of the accessing symbol of that parser
state; used in the generated code for YYDESTRUCT_CALL() &
YYSTYPE_TOSTRING() to enable the correct semantic value union tag to be
determined when executing the implementation of YYDESTRUCT_CALL() or
YYSTYPE_TOSTRING() (similar to yystos[] in bison)
- added to output_prefix(): yystos; yycindex & yyctable if compiling
backtracking; yyloc & yylloc if %locations used
- extended yyname[] to include all grammar symbols, not just the terminal
symbols: '$end', 'error', '$accept', all non-terminals, including internally
generated non-terminals for embedded actions in rules, and 'illegal-symbol'
(which bison spells '$undefined'); '$end' already defined as a symbol 0,
rathern than adding 'end-of-file' as the name of symbol 0; added
'illegal-symbol' from byacc-20140101 (NOTE: the comment in the code that
says byacc does not predefine '$end' and '$error' is incorrect; however,
both bison and byacc spell '$error' as 'error')
- added generation of #define YYTRANSLATE() from byacc-20140101, but changed
the definition for the undefined symbol case because it is no longer in
yyname[YYMAXTOKEN+1] but rather occurs after the last non-terminal symbol;
added #define YYUNDFTOKEN to contain the index in yyname of 'illegal-symbol'
- generate YYLTYPE in output_ltype() as a struct like for bison rather than
using #define in yaccpar.skel
- added 'write_code_lineno' invocation at start of 'output_prefix'
- added 'write_code_lineno' invocation at start of 'output_pure_parser'
- added 'write_code_lineno' invocation prior to generation of #include
for externs file
- added 'write_code_lineno' invocation after 1st 'write_section(fp, xdecls)'
- added '++outline;' prior to output of '#define YYTRANSLATE' - this was
actually causing almost all of the invocations of 'write_code_lineno' to
put out the correct #line directive
- corrected 'write_code_lineno' - the line number in a #line directive is
the number of the next line, not the number of the #line line
- changed MAXSHORT to MAXYYINT; changed 'high' local static from 'int' to
'long' so that it can get higher than 'MAXYYINT' without machine-dependent
behavior; changed related formats from '%d' to '%ld'
- generate 'YYINT' rather than 'short' for integer table types
- generate YYDESTRUCT_DECL & YYDESTRUCT_CALL macros, similar to YYERROR_DECL
and YYERROR_CALL macros, that can be redefined by user, if desired, to add
additional parameters to yydestruct() (and even change the 'yydestruct'
function name)
- if at least one %destructor present, generate yydestruct(); 1st parameter
is a string indicating the context in which yydestruct() is invoked
(e.g., discarding input token, discarding state on stack, cleanup when
aborting); 2nd parameter is the internal grammar symbol number [0..nsyms)
of the accessing symbol of the parser state on the top of the stack; 3rd
parameter is a pointer to the semantic value to be reclaimed associated
with the grammar symbol in the 2nd parameter; if %locations is defined,
the 4th parameter is a pointer to the position value to be reclaimed
associated with the grammar symbol in the 2nd parameter
reader.c
- adopt []-actions, similar to {}-actions; {}-actions are only executed when
not in trial mode, but []-actions are executed regardless of mode
- adopt new symbol class values ACTION and ARGUMENT
- adopt inherited attributes (syntax resembles arguments to non-terminal
symbols)
- adopt keyword table lookup from btyacc, modified to handle equivalence
of '-' and '_' in spelling of keywords
- adopt refactoring of tag table creation into cache_tag() for use in
multiple locations
- added new error functions in place of btyacc's generic error() function
- changed '0' to 'NULL' for pointer initialization
- reworked for-loop at end of get_line (part of DEFERRED '%ifdef/%endif' change)
- added %locations directive for bison compatibility to enable position
processing
- added decl for 'int locations'; true if %locations present
- added decl 'int backtrack'; initialized to 0 (= false), set to
1 (= true) if -B flag is present
- process %locations if present, set location = 1
- only process []-actions and only generate 'if (!yytrial)' prefix for
{}-actions if backtracking is enabled
- add decl for 'int destructor'; true if at least one %destructor is present
- add %destructor directive to enable semantic & position stack processing to
reclaim memory associated with discarded symbols
- process bison compatible %destructor (set destructor = 1); support @$ in
%destructor code to reference the position value if %locations is defined
- changed 'short' to 'Value_t' (in some instances, 'Value_t' was already
used for variables/parameters that were related to variables/parameters
declared as 'short'
- if %locations present, support @N and @$ syntax as for bison to reference
the locations associated with the N-th rhs symbol and the lhs symbol,
respectively
symtab.c
- initialize fields added to 'struct bucket' for non-terminal symbol
inherited attributes
verbose.c
- for parse states with conflicts, the contents of the y.output file include
the trial shift and/or trial reduce actions
- added output to the end of the verbose report showing the correspondance
between grammar symbol #, internal parser symbol #, and grammar symbol name
- changed 'short' to 'Value_t' (in some instances, 'Value_t' was already
used for variables/parameters that were related to variables/parameters
declared as 'short'
yacc.1
- added options 'P', 'V', 'y' and '-o output_file' to the yacc command
synopsis (already covered in the description section)
- added options 'B', 'D' and 'L' to the yacc command synopsis; added text in
the description section
- added %locations description to the extensions section

Tom Shields, March 17, 2014
NOTE: README.BTYACC needs to be re-written (or another README file created)
to explain how the extensions were adopted into the byacc-20140101 baseline.
bytacc changes adopted; see README.BTYACC for details.
------------------------------------------------------
Changes to the skeleton to send debugging output to stderr.
Changes to the types of the grammar tables from 'short' to 'int' if
MAXTABLE is defined to be > MAXSHORT for generation of large grammar tables
for large grammars. This can be set with the invocation of configure
using the --with-max-table-size=N option
Changes to add syntactic sugaring for definition and semantic processing
of inherited attributes associated with non-terminal symbols on the rhs of
rules. Inherited attributes are implemented as {}-actions, and as such may
introduce reduce/reduce conflicts. The advantage over manual {}-actions is
that checking is performed on the number and types of inherited attributes,
and the positions on the semantic stack are automatically calculated.
Identical actions produced by the inherited attribute syntax are collapsed
into a single action, reducing reduce/reduce conflicts.
The %type specification is extended to define the types of inherited
attributes associated with non-terminal symbols on the lhs of rules, in
addition to its original purpose in yacc for specifying the type of the
symbol itself on the parser's value stack. In order to permit the two
aspects to be used independently, the <type> specification following
%type is optional.
Added a mechanism to the parser skeleton for computing and propagating
the text position of grammar symbols if %locations directive is present in
the grammar specificaion, or if yacc is invoked with the -L flag. Includes
support for "@$" and "@N" (for N an integer) in actions to refer to symbol
locations.
Added a bison compatible %destructor directive to define a memory
management mechanism to the parser skeleton that enables cleanup of semantic
values and text positions associated with the parsing stack that are
automatically discarded during error processing.
The following is only available if configure is invoked with the
--enable-btyacc=yes:
Changes to enable backtracking with semantic disambiguation, if yacc is
invoked with the -B flag. A yacc parser disambiguates shift/reduce conflicts
by choosing to shift, and reduce/reduce conflicts by reducing using the
earliest grammar rule (in the grammar specification). A btyacc parser handles
a conflict by remembering the current parse point and entering into trial parse
mode. In trial parse mode, the parser tries each of the conflicting options
until the first successs or until all options are exhausted. If the parser
runs into an error while in trial parse mode, it backtracks to the most recent
conflict point and tries the next alternative. If the parser finds a
successful parse, it backtracks to the point where it first entered trial parse
mode and continues with normal parsing, using the action at the start of the
successful trial path. Success in trial parse mode is achieved either by
successfully reducing the start symbol at the end of input or by invocation of
YYVALID (or YYVALID_NESTED). Semantic disambiguation is supported within
[]-actions, which are always executed, with invocation of YYERROR to terminate
a trial path or YYVALID (and YYVALID_NESTED). Yacc {}-actions are only
executed during normal parsing.
btyacc changes deferred:
------------------------
The -S command line flag to enable use of an alternate parser skeleton,
read from an external file.
Preprocessor statements: %define, %ifdef/%endif, %include.
btyacc changes rejected:
------------------------
The yyerror_detailed() option for error messages is replaced by the
byacc feature for specifying options paramters to yyerror().
C++-specific features in the parser skeleton.

The original README from btyacc is below.
The backtracking enhancements to byacc have been merged into Thomas Dickey's
byacc baseline.
The %include and %define/%ifdef enhancements described below are not currently
incorporated.
-------------------------------------------------------------------------------
BTYACC -- backtracking yacc
===========================
BTYACC was created by Chris Dodd using ideas from many
places and lots of code from the Berkeley Yacc
distribution, which is a public domain yacc clone put
together by the good folks at Berkeley. This code is
distributed with NO WARRANTY and is public domain.
It is certain to contain bugs, which you should
report to: chrisd@collins.com.
Vadim Maslov of Siber Systems <vadik@siber.com>
considerably modified BTYACC to make it suitable
for production environment.
Several people have suggested bug fixes that
were incorporated into BtYacc.
See the README.BYACC files for more about
Berkeley Yacc and other sources of info.
http://www.siber.com/btyacc/ is the current home of BtYacc.
It is provided courtesy of Siber Systems http://www.siber.com/.
Version 3.0 changes
-------------------
by Vadim Maslov
Changes mostly occurred in btyaccpa.ske file that
contains the parsing shift/reduce/backtrack algorithm.
Version 3.0 innovations focus on:
- text position computation and propagation,
- industrial-strength error processing and recovery.
** Added mechanism for computing and propagating
text position of tokens and non-terminals.
Compilers often need to build AST trees such that every node
in a tree can relate to the parsed program source it came from.
The following applications are very likely to need this:
- debuggers that show actual source of the debugged program,
- source-to-source translators that want
unchanged parts of the tree to generate the unchanged code.
The new YYPOSN mechanism added in this version of BtYacc
helps you in automating the text position computation
and in assigning the computed text positions to the AST.
This mechanism is successfully used in commercial
parsers and source-to-source translators.
In standard Yaccs every token and every non-terminal
has an YYSTYPE semantic value attached to it.
In this new version every token and every non-terminal
also has an YYPOSN text position attached to it.
YYPOSN is a user-defined type that can be anything and
that has a meaning of text position attached to
token or non-terminal.
In addition to semantic value stack BtYacc now maintains
text position stack. Behavior of the text position stack
is similar to the behavior of the semantic value stack.
If using text position mechanism,
you need to define the following:
YYPOSN Preprocessor variable that contains C/C++ type of
the text position attached to
every token and non-terminal.
yyposn Global variable of type YYPOSN.
The lexer must assign text position of
the returned token to yyposn, just like it assigns
semantic value of the returned token to yylval.
YYREDUCEPOSNFUNC
Preprocessor variable that points to function that
is called after the grammar rule reduction
to reduce text positions located on the stack.
This function is called by BtYacc to reduce text
positions. The function is called immediately after
the regular rule reduction occurs.
The function has the following prototype:
void ReducePosn(YYPOSN &ret,
YYPOSN *terms,
YYSTYPE *term_vals,
int term_no,
int stk_pos,
int yychar,
YYPOSN &yyposn,
UserType extra);
The function arguments are:
- ret
Reference to the text position returned by
the rule. The function must write the computed
text position returned by the rule to ret.
This is analogue of the $$ semantic value.
- term_posns
Array of the right-hand side rule components
YYPOSN text positions. These are analogues of
$1, $2, ..., $N in the text position world.
- term_vals
Array of the right-hand side (RHS) rule components
YYSTYPE values. These are the $1,...,$N themselves.
- term_no
Number of the components in RHS of the reduced rule.
Equal to size of arrays term_posns and term_vals.
Also equal to N in $1,...,$N in the reduced rule.
- stk_pos
YYSTYPE/YYPOSN stack position before the reduction.
- yychar
Lookahead token that immediately follows
the reduced RHS components.
- yyposn
YYPOSN of the token that immediately follows
the reduced RHS components.
- extra
User-defined extra argument passed to ReducePosn.
Typically this function extracts text positions from
the right-hand side rule components and either
assigns them to the returned $$ structure/tree or
if no $$ value is returned, puts them into
the ret text position from where
it will be picked up by the later reduced rules.
YYREDUCEPOSNFUNCARG
Extra user-defined argument passed to
the ReducePosn function. This argument can use
any variables defined in btyaccpa.ske.
** Added code to btyaccpa.ske that automatically cleans up
semantic semantic values and text positions of tokens
and non-terminals that are discarded and deleted as
a result of error processing.
In the previous versions the discarded token and non-terminal
semantic values were not cleaned that caused quite severe
leaks. The only way to fix it was to add garbage collection
to YYSTYPE class.
Now BtYacc skeleton calls delete functions for semantic
values and positions of the discarded tokens and
non-terminals.
You need to define the following functions that BtYacc
calls when it needs to delete semantic value or text position.
YYDELETEVAL
User-defined function that is called by BtYacc
to delete semantic value of the token or non-terminal.
The user-defined function must have the prototype:
void DeleteYYval(YYSTYPE v, int type);
v is semantic value to delete,
type is one of the following:
0 discarding token
1 discarding state
2 cleaning up stack when aborting
YYDELETEPOSN
User-defined function that is called by BtYacc
to delete text position of the token or non-terminal.
The user-defined function must have the prototype:
void DeleteYYposn(YYPOSN p, int type);
v is semantic value to delete,
type is one of the following:
0 discarding token
1 discarding state
2 cleaning up stack when aborting
** User can define "detailed" syntax error processing
function that reports an *exact* position of
the token that caused the error.
If you define preprocessor variable YYERROR_DETAILED in
your grammar then you need define the following
error processing function:
void yyerror_detailed(char *text,
int errt,
YYSTYPE &errt_value,
YYPOSN &errt_posn);
It receives the following arguments:
text Error message.
errt Code of the token that caused the error.
errt_value Value of the token that caused the error.
errt_posn Text position of token that caused error.
** Dropped compatibility with C.
Compatibility with C became increasingly difficult
to maintain as new features were added to btyaccpa.ske.
So we dropped it. If anybody wants to make the new version
compatible with C, we would gladly accept the changes.
Meanwhile we expect that you use C++ to write grammar
actions and everything else in grammar files.
Since C is (in a sense) subset of C++, your C-based
grammar may work if you use C++ compiler to compile it.
Version 3.0 bugs fixed
----------------------
Matthias Meixner <meixner@mes.th-darmstadt.de> fixed a bug:
BtYacc does not correctly handle typenames, if one typename
is a prefix of another one and if this type is used after
the longer one. In this case BTYacc produces invalid code.
Version 2.1 changes
-------------------
by Vadim Maslov
** Added preprocessor statements to BtYacc that are similar
in function and behavior to C/C++ preprocessor statements.
These statements are used to:
- Introduce modularity into a grammar by breaking it
into several *.y files and assembling different
grammars from the *.y modules using %include and %ifdef.
- Have several versions of the same grammar
by using %ifdef and $endif.
- To include automatically generated grammar fragment.
For instance, we use %include to include
automatically generated list of tokens.
Preprocessor statements are:
%define <var-name>
Define preprocessor variable named <var-name>.
%ifdef <var-name>
If preprocessor variable named <var-name>
is defined by %define, then process the text from
this %ifdef to the closing %endif.
%endif
Closing bracket for %ifdef preprocessor statement.
Only one nesting level of %ifdef-%endif is allowed.
%include <file-name>
Process contents of the file named <file-name>.
If <file-name> is a relative name, it is looked up
in a directory in which btyacc was started.
Only one nesting level of %include is allowed.
Version 2.0 changes
-------------------
by Vadim Maslov
** Changed 16-bit short numbers to 32-bit int numbers in
grammar tables, so that huge grammar tables (tables that
are larger than 32768 elements) resulting from huge
grammars (Cobol grammar, for instance) can work correctly.
You need to have 32-bit integer to index table bigger than
32768 elements, 16-bit integer is not enough.
The original BtYacc just generated non-working tables
larger than 32768 elements without even notifying about
the table overflow.
** Make error recovery work correctly when error happens
while processing nested conflicts. Original BtYacc could
infinitely cycle in certain situations that involved error
recovery while in nested conflict.
More detailed explanation: when we have nested conflicts
(conflict that happens while trial-processing another
conflict), it leads btyacc into NP-complete searching of
conflict tree. The ultimate goal is YYVALID operator that
selects a particular branch of that tree as a valid one.
If no YYVALID is found on the tree, then error recovery
takes over. The problem with this is that error recovery
is started in the same state context that exists on the
last surveyed branch of the conflict tree. Sometimes this
last branch may be of zero length and it results in
recovering to exactly the same state as existed before
entering the conflict. BtYacc cycles then.
We solved this problem by memorizing the longest path in
the conflict tree while browsing it. If we ever get into
error recovery, we restore state that existed on the
longest path. Effectively we say: if we have an error,
let us move forward as far as we possibly could while we
were browsing the conflict tree.
** Introduce YYVALID_NESTED operation in addition to
simply YYVALID. When we have a nested conflict (conflict
while processing in trial mode for another conflict), we
want to relate YYVALID to a particular level of conflict
being in trial.
Since we mostly anticipate only 2-level nested conflicts
YYVALID_NESTED tells the parser to satisfy only the
internal conflict. Therefore, in 1-level conflict
situation YYVALID_NESTED acts like a regular YYVALID, but
in 2-level conflict it is a no-op and the other YYVALID
for outer conflict will be searched for.
** Improved handling of situation where /tmp directory is
missing. Original btyacc just died quietly when /tmp
directory was missing. We added code that states the
problem explicitly. While on UNIX /tmp directory is always
present, it may be missing on WIN32 systems, therefore
diagnosing this situation is important.
Version 1.0 changes: BackTracking
=================================
by Chris Dodd
BTYACC is a modified version of yacc that supports
automatic backtracking and semantic disambiguation to
parse ambiguous grammars, as well as syntactic sugar for
inherited attributes (which tend to introduce conflicts).
Whenever a btyacc generated parser runs into a
shift-reduce or reduce-reduce error in the parse table, it
remembers the current parse point (yacc stack and input
stream state), and goes into trial parse mode. It then
continues parsing, ignoring most rule actions. If it runs
into an error (either through the parse table or through
an action calling YYERROR), it backtracks to the most
recent conflict point and tries a different alternative.
If it finds a successful parse (reaches the end of the
input or an action calls YYVALID), it backtracks to the
point where it first entered trial parse mode, and
continues with a full parse (executing all actions),
following the path of the successful trial.
Actions in btyacc come in two flavors -- {}-actions, which
are only executed when not in trial mode, and []-actions
which are executed regardless of mode. There are also
inherited attributes, which look like arguments (they are
enclosed in "()") and act like []-actions.
What this buys you:
* No more lexer feedback hack. In yacc grammars for C, a
standard hack, know as the "lexer feedback hack" is used
to find typedef names. The lexer uses semantic
information to decide if any given identifier is a
typedef-name or not and returns a special token. With
btyacc, you no longer need to do this; the lexer should
just always return an identifier. The btyacc grammar then
needs a rule of the form:
typename: ID [ if (!IsTypeName(LookupId($1))) YYERROR; ]
While the hack works adequately well for parsing C, it
becomes a nightmare when you try to parse something like
C++, where treating an ID as a typedef becomes heavily
dependent on context.
* Easy disambiguation via simple ordering. Btyacc runs
its trials via the rule "try shifting first, then try
reducing by the order that the conflicting rules appear in
the input file". This means you can deal with semantic a
disambiguation rule like:
[1] If it looks like a declaration it is, otherwise
[2] If it looks like an expression it is, otherwise
[3] it is a syntax error
[Ellis&Stroustrup, Annotated C++ Reference Manual, p93]
To deal with this, you need only put all the rules for
declarations before the rules for expressions in the
grammar file.
* No extra cost if you do not use it. Backtracking is
only triggered when the parse hits a shift/reduce or
reduce/reduce conflict in the table. If you have no
conflicts in your grammar, there is no extra cost, other
than some extra code which will never be invoked.
* C++ and ANSI C compatible parsers. The parsers produced
by btyacc can be compiled with C++ correctly. If you
"#define" YYSTYPE to be some C++ type with constructor and
destructor, everything will work fine. My favorite is
"#define YYSTYPE SmartPointer", where SmartPointer is a
smart pointer type that does garbage collection on the
pointed to objects.
BTYACC was originally written to make it easy to write a
C++ parser (my goal was to be able to use the grammar out
of the back of the ARM with as few modifications as
possible). Anyone who has ever looked at Jim Roskind
public domain C++ yacc grammar, or the yacc-based grammar
used in g++ knows how difficult this is. BTYACC is very
useful for parsing any ambiguous grammar, particularly
ones that come from trying to merge two (or more) complete
grammars.
Limitations of the backtracking: Currently, the generated
parser does NO pruning of alternate parsing paths. To
avoid an exponential explosion of possible paths (and
parsing time), you need to manually tell the parser when
it can throw away saved paths using YYVALID. In practice,
this turns out to be fairly easy to do. A C++ parser (for
example) can just put a [YYVALID;] after every complete
declaration and statement rule, corresponding to pruning
the backtracking state after seeing a ';' or '}' -- there
will never be a situation in which it is useful to
backtrack past either of these.
Inherited attributes in btyacc:
Inherited attributes look a lot like function arguments to
non-terminals, which is what they end up being in a
recursive descent parser, but NOT how they are implemented
in btyacc. Basically they are just syntactic sugar for
embedded semantic actions and $0, $-1, ... in normal yacc.
btyacc gives you two big advantages besides just the
syntax:
1. it does type checking on the inherited attributes,
so you do not have to specify $<type>0 and makes sure
you give the correct number of arguments (inherited
attributes) to every use of a non-terminal.
2. It "collapses" identical actions from that are produced
from inherited attributes. This eliminates many
potential reduce-reduce conflicts arising from
the inherited attributes.
You use inherited attributes by declaring the types of the
attributes in the preamble with a type declaration and
declaring names of the attributes on the lhs of the yacc
rule. You can of course have more than one rule with the
same lhs, and you can even give them different names in
each, but the type and number must be the same.
Here is a small example:
/* lhs takes 2 inherited attributes */
%type <t1> lhs(<t1>, <t2>)
stuff(<t1>, <t2>)
%%
lhs($i1, $i2) : { $$ = $i1 }
| lhs($i1, $i2) stuff($1,$i2) { $$ = $2; }
This is roughly equivalent to the following yacc code:
lhs :
{ $$ = $<t1>-1; }
| lhs [ $<t1>$ = $-1; ] [ $<t2>$ = $<t2>0; ] stuff
{ $$ = $4; }
;
See the file "test/t2.y" for a longer and more complete
example. At the current time, the start symbol cannot
have any arguments.
Variant parsers:
Btyacc supports the -S flag to use a different parser
skeleton, changing the way that the parser is called and
used. The skeleton "push.skel" is included to produce a
"passive" parser that you feed tokens to (rather than
having the parser call a separate yylex routine). With
push.skel, yyparse is defined as follows:
int yyparse(int token, YYSTYPE yylval)
You should call yyparse repeatedly with successive tokens
of input. It returns 0 if more input is needed, 1 for a
successful parse, and -1 for an unrecoverable parse error.
Miscellaneous Features in ver. 1.0
----------------------------------
by Chris Dodd
The -r option has been implemented. The -r option tells
Yacc to put the read-only tables in y.tab.c and the code and
variables in y.code.c. Keith Bostic asked for this option so
that :yyfix could be eliminated.
The -l and -t options have been implemented. The -l
option tells Yacc not to include #line directives in the code
it produces. The -t option causes debugging code to be
included in the compiled parser.
The code for error recovery has been changed to
implement the same algorithm as AT&T Yacc. There will still
be differences in the way error recovery works because AT&T
Yacc uses more default reductions than Berkeley Yacc.
The environment variable TMPDIR determines the directory
where temporary files will be created. If TMPDIR is defined,
temporary files will be created in the directory whose
pathname is the value of TMPDIR. By default, temporary files
are created in /tmp.
The keywords are now case-insensitive. For example,
%nonassoc, %NONASSOC, %NonAssoc, and %nOnAsSoC are
all equivalent.
Commas and semicolons that are not part of C code are
treated as commentary.
Line-end comments, as in BCPL, are permitted. Line-end
comments begin with // and end at the next end-of-line.
Line-end comments are permitted in C code; they are converted
to C comments on output.
The form of y.output files has been changed to look more
like those produced by AT&T Yacc.
A new kind of declaration has been added.
The form of the declaration is
%ident string
where string is a sequence of characters beginning with a
double quote and ending with either a double quote or the
next end-of-line, whichever comes first. The declaration
will cause a #ident directive to be written near the start
of the output file.
If a parser has been compiled with debugging code, that
code can be enabled by setting an environment variable.
If the environment variable YYDEBUG is set to 0, debugging
output is suppressed. If it is set to 1, debugging output
is written to standard output.
Building BtYacc
---------------
by Chris Dodd and Vadim Maslov
We used GCC and GNU make to compile BtYacc both on UNIX and
WIN32 paltforms. You are welcome to try different
combinations of makes and compilers. Most likely it will
work, but it may require Makefile changes.
There is no config script.
Just type "make" and it should compile.
AWK. If you want to change file btyaccpa.ske (backtracking
parser skeleton), you will need awk to compile it into
skeleton.c file. We used GNU AWK (gawk) version 3.0.
It is known that using older versions of gawk
may create problems in compilation, because older awks
have problems with backslashes at the end of a line.
For MSDOS, there a "makefile.dos" that should do the trick.
Note: makefile.dos was not tested for a long time.
The result of compilation should be a single executable called
"btyacc" which you can install anywhere you like;
it does not require any other files in the distribution to run.
