<http://lists.gnu.org/archive/html/bison-patches/2007-11/msg00021.html>.
* 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.
* tests/c++.at: Likewise.
* tests/calc.at: Likewise.
* tests/conflicts.at: Likewise.
* tests/cxx-type.at: Likewise.
* tests/existing.at: Likewise.
* tests/glr-regression.at: Likewise.
* tests/headers.at: Likewise.
* tests/input.at: Likewise.
* tests/java.at: Likewise.
* tests/output.at: Likewise.
* tests/push.at: Likewise.
* tests/reduce.at: Likewise.
* tests/regression.at: Likewise.
* tests/sets.at: Likewise.
* tests/skeletons.at: Likewise.
* tests/synclines.at: Likewise.
* tests/torture.at: Likewise.
(Big triangle): Use AT_BISON_CHECK_NO_XML instead since this grammar
tends to hang xsltproc.
(Big horizontal): Likewise.
<http://lists.gnu.org/archive/html/help-bison/2007-09/msg00016.html>.
* data/c++.m4: (b4_namespace_ref, b4_namespace_open,
b4_namespace_close): New macros that interpret the %define variable
"namespace" so its value can contain "::" to indicate nested
namespaces.
* data/glr.cc (b4_namespace): Don't define, and replace all uses with
the above macros.
* data/lalr1.cc (b4_namespace): Likewise.
* data/location.cc (b4_namespace): Likewise.
* doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
inside a new table in the general %define entry. Document `%define
namespace' there as well. Point the %name-prefix entry to it since it
explains it more completely in the case of C++.
(C++ Bison Interface): Mention `%define namespace' instead of
%name-prefix.
(Table of Symbols): Remove the `%define push_pull' entry. The %define
entry suffices.
* tests/c++.at (Relative namespace references): New test case.
(Absolute namespace references): New test case.
(Syntactically invalid namespace references): New test case.
* tests/input.at (C++ namespace reference errors): New test case.
(parser::state_type, parser::semantic_type, parser::location_type):
Private, not public.
(parser::parse): Return ints, not bool.
Returning a bool introduces a problem: 0 corresponds to false, and
it seems weird to return false on success. Returning true changes
the conventions for yyparse.
Alternatively we could return void and send an exception.
There is no clear consensus (yet?).
(state_stack, semantic_stack, location_stack): Rename as...
(state_stack_type, semantic_stack_type, location_stack_type): these.
Private, not public.
* tests/c++.at: New.
* tests/testsuite.at, tests/Makefile.am: Adjust.
