Don't use std::endl, it flushes uselessly, and is considered bad
style.
Building C++ parsers with -Wsuggest-attribute=const and
-Wsuggest-attribute=noreturn triggers warning in generated code.
* data/lalr1.cc: Call b4_attribute_define.
(debug_stream, debug_level): Flag as pure.
* tests/headers.at (Several parsers): There are now more YY macros
that "leak".
* tests/local.at (AT_NAME_PREFIX): Also match api.namespace.
(AT_MAIN_DEFINE): Take it into account.
* tests/c++.at, tests/headers.at: Use AT_NAME_PREFIX.
(AT_CHECK_NAMESPACE): Rename as...
(AT_TEST): this.
Reported by Théophile Ranquet.
* tests/glr-regression.at: Rewrite some test cases so that AT_PARSER_CHECK,
which runs valgrind, is exposed with the parser, not with "echo".
* tests/local.at, tests/regression.at, tests/headers.at:
Use AT_PARSER_CHECK for generated parsers.
Does not work on Solaris 10. Reported by Dennis Clarke.

* tests/headers.at (Several parsers): Use Perl instead.
While at it, run it only once, on all the generated headers.
Adjust to YY_NULL be defined in position.hh.
Reported by Rob Vermaas' Hydra build farm on x86_64-darwin 10.2.0 with
G++ 4.6.3.
* tests/headers.at (Several parsers): Include AT_DATA_SOURCE_PROLOGUE
in the files to compile.
* data/location.cc: Do not include twice string and iostream (once
by position.hh, and then by location.hh).
* README-hacking (Typical errors): Some hints for other maintainers.

* configure.ac (XSLTPROC): New substitution.
* Makefile.am (maintainer-xml-check): New phony target invoking...
* tests/Makefile.am (maintainer-xml-check): ... this new phony target
invoking make maintainer-check with BISON_TEST_XML=1.
* tests/atlocal.in (XSLTPROC): New.
* tests/local.at (AT_BISON_CHECK): New macro to (1) instruct Valgrind
not to report reachable memory when Bison is expected to have a
non-zero exit status and (2) to compare XML/XSLT output with --graph
and --report=all output for every working grammar when
BISON_TEST_XML=1.
(AT_BISON_CHECK_NO_XML): Likewise, but skip XML checks.
(AT_BISON_CHECK_XML): New.
(AT_QUELL_VALGRIND): New.
* tests/testsuite.at (ORIGINAL_AT_CHECK): Remove this and...
(AT_CHECK): ... don't redefine this since this was the old way to
quell Valgrind.
* tests/actions.at: Rewrite all AT_CHECK invocations for bison as
AT_BISON_CHECK invocations.

(Big triangle): Use AT_BISON_CHECK_NO_XML instead since this grammar
tends to hang xsltproc.
(Big horizontal): Likewise.
(whether successful or failed) so that yypush_parse can be invoked
again to start a new parse using the same yypstate.
* tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
check multiple yypull_parse invocations on the same yypstate. For pull
mode, extend to check multiple yyparse invocations.
(Exploding the Stack Size with Alloca): Extend to try with
%push-pull-parser.
(Exploding the Stack Size with Malloc): Likewise.
* tests/calc.at (Simple LALR Calculator): Don't specify
%skeleton "push.c" since %push-pull-parser implies that now.
* tests/headers.at (export YYLTYPE): Don't check for the push
declarations. Otherwise, this test case can't be used to see if push
mode can truly emulate pull mode.
* tests/input.at (Torturing the Scanner): Likewise.
* tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
(AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
AT_YACC_IF, which now includes the case of push mode since %skeleton
need not be used for push mode. This will be more intuitive once
push.c is renamed to yacc.c.
instead of passing a yylexp argument to yypull_parse, and don't
generate yypull_parse or yyparse unless %push-pull-parser is declared.

* data/bison.m4 (b4_pull_if): New.
* data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
* data/push.c: Improve M4 quoting a little.
(b4_generate_macro_args, b4_parenthesize): Remove.
(yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
any time a pull parser is requested.
Don't #define this as a wrapper around yypull_parse. Instead, when
both push and pull are requested, make it a function that does that
same thing.
(yypull_parse): If there's a b4_prefix, #define this to
b4_prefix[pull_parse] when both push and pull are requested.
Don't define this as a function unless both push and pull are
requested.
Remove the yylexp argument and hard-code yylex invocation instead.
* etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
%push-parser.
* src/getargs.c (pull_parser): New global initialized to true.
* getargs.h (pull_parser): extern it.
* src/output.c (prepare): Insert pull_flag muscle.
* src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
(prologue_declaration): Set both push_parser and pull_parser = true for
%push-pull-parser. Set push_parser = true and pull_parser = false for
%push-parser.
* src/scan-gram.l: Don't accept %push_parser as an alternative to
%push-parser since there's no backward-compatibility concern here.
Scan %push-pull-parser.
* tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
instead of %push-parser.
* tests/headers.at (export YYLTYPE): Make yylex static, and don't
prototype it in the module that calls yyparse.
* tests/input.at (Torturing the Scanner): Likewise.
* tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
* data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
(yypull_parse): New function wrapping yypush_parse.
(yyparse): New #define wrapping yypull_parse.
* tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
is declared.
* tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
prototype yylex in the module that calls yyparse, and don't prototype
yyparse there. Otherwise, the yyparse expansion won't compile.
* tests/input.at (Torturing the Scanner): Likewise.
