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:
|
||||
-------------------------------------------
|
||||
|
||||
push.skel
|
||||
- skeleton for a 'push' parser
|
||||
- needs to be upgraded match the structure of yaccpar.skel
|
||||
|
||||
defs.h
|
||||
- adopt '%include' changes
|
||||
- adopt '%define'/'%ifdef'/'%endif'
|
||||
- adopt -E flag to print preprocessed grammar to stdout
|
||||
|
||||
error.c
|
||||
- adopt '%include' changes
|
||||
- NOTE: there is a btyacc change that might be worth adopting in byacc
|
||||
[FileError() refactoring to eliminate duplicated code in most of the
|
||||
error message functions]
|
||||
|
||||
main.c
|
||||
- adopt '%define' changes
|
||||
- adopt '-DNAME' command line option to define preprocessor variable NAME
|
||||
- adopt -E flag to print preprocessed grammar to stdout
|
||||
- adopt '-S skeleton_file' command line option to select an alternate parser
|
||||
skeleton file
|
||||
- the skeleton file named by the -S flag is used as provided to open the
|
||||
file; consider a change to this behavior to check whether the named file
|
||||
has a path prefix, and if not, look in 'installation' directory if the
|
||||
file is not found in the working directory
|
||||
|
||||
output.c
|
||||
- adopt '%include' changes
|
||||
|
||||
reader.c
|
||||
- adopt '%include' changes
|
||||
- adopt '%define'/'%ifdef'/'%endif' changes
|
||||
- adopt -E flag to print preprocessed grammar to stdout
|
||||
- NOTE: there is a btyacc change that might be worth adopting in byacc
|
||||
[copy_string() & copy_comment() refactoring to eliminate duplicated
|
||||
code in copy_text() and copy_union()]
|
||||
|
||||
warshall.c
|
||||
- NOTE: there is a btyacc change that might be worth adopting in byacc
|
||||
[shifting 'mask' incrementally rather than literal '1' by a variable
|
||||
amount each time thru the loop]
|
||||
|
||||
|
||||
================================================================================
|
||||
|
||||
|
||||
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
|
||||
- adopt error functions from inherited attribute processing; added new error
|
||||
functions
|
||||
- added keyword code LOCATIONS for %locations
|
||||
- added keyword code DESTRUCTOR for %destructor
|
||||
- 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
|
||||
declared as 'short'
|
||||
|
||||
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

|
||||
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.
