New, default to 1.
* data/yacc.c, data/glr.c, data/location.cc: Use them.
* NEWS, doc/bison.texinfo: The initial column and line are 1 by
default.
* tests/calc.at: Adjust.
<http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
* data/c++.m4 (b4_define_location_comparison): New boolean %define
declaration indicating whether filename_type has an operator==. If
filename_type is `std::string', it defaults to `1', `0' otherwise.
* data/location.cc: Iff b4_define_location_comparison is `1', add
operator== and operator!= for class position and for class location.
Some minor fixes.
* src/scan-action.l: Remove unused file.
* src/symtab.c (symbol_printer_set): Use printer_location not
destructor_location.
* src/symtab.h (struct symbol): Replace incorrect source comment for
printer members.
* tests/input.at (Incompatible Aliases): Update output with correct
printer location.
skeletons here, so we don't have to put it in each skeleton. All
uses changed. Wrap the copyright notice, in case it is longer
than 80 columns. Replace comma by newline after title.
the copyright notice. Use more-regular format for titles and
copyright notices.
* data/glr.cc: Likewise.
* data/location.cc: Likewise.
* data/yacc.cc: Likewise.
* doc/bison.texinfo (Conditions): Document this.
* NEWS: likewise. Upgrade version to 2.2.
The test suite already exercize these cases.
* data/c++.m4 (b4_namespace): New.
* data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
* data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
* data/yacc.c, data/glr.c: Remove a useless `[]'.
* doc/bison.texinfo: Document it.
(Option Cross Key): Use @multitable in all formats. It looks
nicer, even in TeX outputs.
(Rules): Use the same code whatever the output type is.
* tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
(_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
* tests/calc.at: Use it, instead of hard coding `yy'.
* data/glr.cc (b4_parse_param_orig): New.
(b4_parse_param): Improve its definition, and bound it more
clearly in the skeleton.
(b4_epilogue): Append, instead of prepending, in order to keep
#line consistency.
Simplify the generation of auxiliary functions: locations and
purity are mandated.
(b4_global_tokens_and_yystype): Honor it.
* data/location.cc (c++.m4): Don't include it.
* tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF
and AT_SKEL_CC_IF.
* tests/calc.at (AT_CHECK_CALC): Rely on AT_SKEL_CC_IF instead of
AT_LALR1_CC_IF.
Be sure to initialize the first position's filename.
(AT_CHECK_CALC_LALR1_CC): Add %location and %defines, they are
mandated anyway.
(AT_CHECK_CALC_GLR_CC): New.
Use it to exercise glr.cc as a lalr1.cc drop-in replacement.
it's no longer just a file.
* data/glr.c: Grant a special exception for C GLR parsers, that
reads like the already-existing exception for C LALR(1) parsers.
* data/glr.cc: Likewise.
* data/lalr1.cc: Likewise.
* data/location.cc: Likewise.
* data/yacc.c: Reword the "written by" statement to clarify that
it was the parser skeleton, not the entire output file.
* data/glr.c: Written by Paul Hilfinger.
* data/glr.cc: Written by Akim Demaille.
* data/lalr1.cc: Likewise.
* data/location.cc (position::initialize, location::initialize): New.
(position::position, location::location): Define only if
b4_location_constructors is defined.
* data/lalr1.cc (b4_location_constructors): Define it for backward
compatibility.
* doc/bison.texinfo (Initial Action Decl): Use initialize.
(xlc and xlC_r) reported by John P. Hartmann.
* data/location.cc (initial_column, initial_line): Remove.
All uses replaced by 0 and 1.
* src/scan-gram.l (gram_wrap): Redefine to avoid bug in flex 2.5.31
that xlc complains about.
* src/scan-skel.l (skel_wrap): Likewise.
