* 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.
* data/glr.c: Use American spacing, for consistency.
* data/glr.cc: Likewise.
* data/lalr1.cc: Likewise.
* data/yacc.c: Likewise.
* data/yacc.c: Reformat comments slightly.
* doc/bison.texinfo: Replace "non-" with "non" when that makes sense,
for consistency. Fix some spelling errors and reword recently-included
text slightly.
* tests/cxx-type.at: Cast results of malloc, for C++.
* data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
Prepend /*ARGSUSED*/, for lint's sake.
* data/glr.c (YYUSE): Properly parenthesize, and use an alternate
definition if 'lint' is defined.
(YYID): New macro (or function, if lint).
All uses of /*CONSTCOND*/0 replaced by YYID(0).
* data/yacc.c: Likewise.
* data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
(yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
* data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
is C++ only.
* data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
* data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
Use YYID(0) rather than 0, for lint.
(yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
(yysyntax_error): Rewrite to avoid lint warnings about parenthesization.
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/c.m4 (b4_parse_param_for, b4_parse_param_use): New.
* data/glr.c, data/glr.cc: Use them.
* data/glr.c (YYUSE): Have a C++ definition that supports
non-pointer types.
