ac695f7df5 * data/lalr1.cc (yy::Position::lines, yy::Position::columns, 
yy::Location::lines, yy::Location::columns): Rename arguments
to avoid shadowing; this removes a warning generated by GCC 3.3.

26ec81e097 Don't pass C-only options to g++. 
Fix YYFILL in GLR parsers to conform to the C standard.
Fix infinite loops in yacc.c, and add a test case.

c6ae27df0b * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate 
YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
This fixes a problem reported by John Bowman when the Compaq/HP
Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
-ansi -Wall -gall).
* data/yacc.c (union yyalloc): Likewise.
(YYCOPY): Do not evaluate __GNUC__ unless it is defined.

6b2584b7a2 Require a semicolon after a grammar declaration, in the interest of 
possible future changes to the Bison input language.
Do not allow a stray semicolon at the start of the grammar.
Allow one or more semicolons after any rule, including
just before "|" as required by POSIX.

caf37a3666 %parse-param support for lalr1.cc. 
* data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
b4_cc_constructor_calls, b4_cc_constructor_call,
b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
definitions.
(yy::b4_parser_class_name::b4_parser_class_name): Take extra
parse-param arguments.
(yy::b4_parser_class_name): Declare instance variables to
hold parse-param arguments.
* tests/calc.at: s/value/semantic_value/ because value clashes
with a member of yy::b4_parser_class_name.  Adjust C++ code
to handle %parse-param.  Enable %parse-param test in C++.

537636c7e5 Fix "Bison blows chunks on empty file" bug. 
Work around SunOS 4.1.4 porting problem with <sys/resource.h>.
Don't check for sys/wait.h twice, with two different algorithms.

snapshot of Bison didn't build on Solaris 7 due to strnlen problems.

c47495657b * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to 
generate verbose error messages.
Use the number of tokens as an upper bound in yytname, as it
cannot be a non terminal.

22e304a6da Write a test the yycheck overrun reported by Andrew Suffield. 
* tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
Use them to exercise yycheck overrun.
Based on Andrew Suffield's grammar.

9c2b381f79 Minor improvements to today's scan-gram.l bugfix. 2003-03-02 06:56:06 +00:00
Akim Demaille
0433ba88f9 * src/scan-gram.l (code_start): Always initialize it when entering 
into yylex, as SC_EPILOGUE is activated *before* the corresponding
yylex invocation.  An alternative would be making it static, but
then it starts with the second %%'s beginning, instead of its end.
 2003-03-01 10:55:31 +00:00
Paul Eggert
b305ea6918 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work

but let's keep mentioning them for now.  Put <> around email
addresses.  Add copyright notice.

f939fc12fe * data/lalr1.cc: Use temporary variables instead of casts to 
change integer types.

95923bd6a6 * doc/bison.texinfo: Use "location" consistently to refer to @n, 
to avoid confusions with lalr1.cc's notion of Position.
Suggested by Paul Eggert.

Akim Demaille
2cdc240eeb * data/lalr1.cc (position.hh): Make sure "columns" never pushes 
before initial_columns.
(location.hh): Use consistent variable names when defining the
operator<<.
Use "last" so that we subtract from Positions, not from unsigned.

AT_YACC_IF.
Redefine AT_YYERROR_SEES_LOC_IF using it.
(_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
not defined.
Don't use the location in yy::Parser::error_ and
yy::Parser::print_ when not %locations.
Activate more lalr1.cc tests.
 2003-02-20 08:14:27 +00:00
