* doc/bison.texinfo (Locations Overview): Rename node to...
(Locations): ... this, which is its section name. Update menus to
match that and not to use the title `Tracking Locations', which is
a different section.
* doc/bison.texinfo (Locations): Rename node to...
(Tracking Locations): ... this, which is its section name, and
update all cross references. The trouble is that there is another
node about locations. Its section name is `Locations', which was
easily confused with the node name of this node. Moreover, its
node name is `Locations Overview', which was mistakenly used to
label some cross references to this node.
* doc/bison.texinfo (Named References): Rename section to match
the node name, and update all cross references. Don't use the
acronyms RHS and LHS given that we don't expand them anywhere in
the manual. Try to use @samp and @code properly. Mention that
named references are experimental as we've already stated in NEWS.
(Destructor Decl): Expand the only remaining use of RHS or LHS.

* NEWS (2.5.1): Document.
* doc/bison.texinfo (Named References): Because it discusses
locations in addition to semantic values, move this subsection out
of the section `Defining Language Semantics', where locations have
not yet been introduced, to be a new section after the following
section, `Tracking Locations'.
* README-hacking (Updating a submodule): Give advice on how to
determine the versions of gnulib and autoconf to which we should
update.
(Release Procedure): Note that submodules should be updated.
* bootstrap.conf (gnulib_modules): Rename pipe to spawn-pipe as
suggested in updated gnulib NEWS.
* gnulib: Choose a stable snapshot according to advice in Bison's
README-hacking.
* po/POTFILES.in (lib/pipe.c): Rename to...
(lib/spawn-pipe.c): ... this.
* src/output.c: Update to include spawn-pipe.h.
* submodules/autoconf: Update to latest for improvement in m4.m4
that excludes M4 with buggy strstr. The only other changes to
files that we use are copyright updates.

* src/conflicts.c (conflicts_print): Suppress conflict report
based on -Wno-conflicts-sr and -Wno-conflicts-rr, and treat
conflicts as errors if -Werror.
* src/getargs.c (warnings_flag): Initialize with
warnings_conflicts_sr and warnings_conflicts_rr as well.
(warnings_args, warnings_types): Add entries for
warnings_conflicts_sr and warnings_conflicts_rr.
(usage): Update.
* src/getargs.h (enum warnings): Add entries for
warnings_conflicts_sr and warnings_conflicts_rr.
* tests/conflicts.at (-W versus %expect and %expect-rr): New test
group.
* tests/local.at (AT_BISON_CHECK_NO_XML): Update now that the
conflict report can produce a "warnings being treated as errors"
message. Also, check that stderr is now fully scrubbed by -Wnone
when the exit status is 0.

* doc/bison.texinfo (Bison Options): Document.
* src/complain.c, src/complain.h
(warn_at, warn_at_indent, warn): Suppress warning if -Wno-other.
(midrule_value_at): New warning function, similar to yacc_at in
that it's controlled by its own warning category.
* src/getargs.c (warnings_flag): Initialize to warnings_other.
(warnings_args, warnings_types): Add entry for warnings_other.
(usage): Update.
* src/getargs.h (enum warnings): Add entry for warnings_other.
* src/gram.c (grammar_rules_useless_report): If -Wno-other, then
don't print useless rules.
* src/reader.c (symbol_should_be_used): Rather than adjusting the
return value based on whether midrule value warnings are enabled,
accept a new parameter for telling the caller whether true is
being returned for a potential midrule warning.
(grammar_rule_check): Use midrule_value_at for midrule value
warnings, and continue to use warn_at for all other warnings. Let
them check whether the warnings are enabled.
* tests/local.at (AT_BISON_CHECK): Update documentation.
(AT_BISON_CHECK_NO_XML): Check that -Wnone and --warnings=none
disable all warnings exercised in the test suite.
* doc/bison.texinfo (Mystery Conflicts): Rename node to...
(Mysterious Conflicts): ... this, which is already the section
title and the name used in the index. Update all cross-references
to this node. Also, don't imply that R/R conflicts are the only
kind of mysterious conflict.
States that shift the error token do not have default reductions,
and GLR disables some default reductions, so "all" was a misnomer.
* doc/bison.texinfo (%define Summary): Update.
(Default Reductions): Update.
* src/print.c (print_reductions): Update.
* src/reader.c (prepare_percent_define_front_end_variables):
Update.
* src/tables.c (action_row): Update.
* tests/input.at (%define enum variables): Update.
* tests/reduce.at (%define lr.default-reductions): Update.
And clean up all other documentation of the features described
there.
* NEWS (2.5): Tweak wording of lr.type and parse.lac entries a
bit, update the cross-references to the manual, and point out that
LAC has caveats. Don't be so adamant that IELR+LAC=canonical LR.
That is, as the referenced section in the manual documents, LAC
does not fix infinite parsing loops on syntax errors.
* doc/bison.texinfo: Consistently drop the "(1)" suffix from LALR,
IELR, and LR in @cindex.
(%define Summary): Condense the entries for lr.default-reductions,
lr.keep-unreachable-states, lr.type, and parse.lac into brief
summaries, and cross-reference the appropriate subsections of
Tuning LR. For parse.lac, mention that it's only implemented for
deterministic parsers in C.
(Error Reporting): When mentioning %error-verbose, mention LAC,
and add cross-reference to the LAC section.
(Tuning LR): New section with an extended version of the
documentation removed from %define Summary. Change all
cross-references in the manual to point here instead of there.
(Calc++ Parser): When mentioning %error-verbose, mention LAC, and
add cross-reference to the LAC section.
(Table of Symbols): In %error-verbose and YYERROR_VERBOSE entries,
add cross-references to Error Reporting.
(Glossary): Capitalize entry titles consistently. Add definitions
for "defaulted state" and "unreachable state". Expand IELR
acronym in IELR's entry.
* doc/bison.texinfo (Mystery Conflicts): Cross-reference
bibliography instead of citing publications directly.
(Generalized LR Parsing): Likewise.
(Bibliography): New section. Not all entries are cross-referenced
yet, but that will come in future patches.
* doc/bison.texinfo (Local Variables): Move this after the
LocalWords, since the latter are looked for in the whole document,
while the former are looked for only at its end.
Require american spell checking.
(cherry picked from commit e944aaff36)
* doc/bison.texinfo (%define Summary): Reword so it reads well as
a separate section. For example, add an intro, and move most of
the text outside of the @deffn so it is not indented so far.
(%code Summary): Likewise.
(Table of Symbols): Reword %code entry to match the %code entry in
Decl Summary.
Suggested by Akim Demaille at
<http://lists.gnu.org/archive/html/bison-patches/2009-05/msg00013.html>.
* doc/bison.texinfo (Decl Summary): Extract most of the %define
entry into...
(%define Summary): ... this new subsection, and update all
cross-references. For readability of the patches, rewriting of
the text so it makes sense as a separate subsection will come in a
later patch. Moreover, the majority of the text describing the
various new LR features should likely move to another new section
somewhere.

The Bison manual's names for various files associated with a Bison
parser has devolved into inconsistency. This patch makes the
naming consistent for the most important files. First, it chooses
"grammar file" over "input file". The former appears to be more
traditional in the Bison manual, and Bison has other input
files (skeletons). Second, it chooses "parser implementation
file" over names like "parser file", "parser source file", "parser
source code file", and "parser output file". The new name makes
it clearer where Bison generates the main parser implementation,
and it is easily distinguishable from "parser header file".
* doc/bison.texinfo: Implement throughout.
* doc/bison.texinfo (Introduction): Don't imply that only Robert
Corbett, Richard Stallman, and Wilfred Hansen have contributed to
Bison. However, I don't have time to write a full history, so
just point readers to THANKS and ChangeLog.
* doc/bison.texinfo (Introduction): Say that IELR(1) and canonical
LR(1) are experimental. Mention Java. Normally experimental
features probably shouldn't be mentioned in the introduction.
However, if Bison's limitations to LALR(1), C, and C++ are so
important that they should be mentioned here, then it's important
to point out that Bison is beginning to escape those limitations.
Moreover, these particular experimental features have very little
chance of being removed.
* src/getargs.c (usage): Say that IELR(1) and canonical LR(1) are
experimental.
This cleans up our previous fixes for a bug whereby Bison
discarded `.field' in `$-1.field'. The previous fixes were less
restrictive about where a dash could appear in an identifier, but
the restrictions were hard to explain. That bug was reported and
this final fix was originally suggested by Paul Hilfinger. This
also fixes a remaining bug reported by Paul Eggert whereby Bison
parses `%token ID -123' as `%token ID - 123' and handles `-' as an
identifier. Now, `-' cannot be an identifier. Discussed in
threads beginning at
<http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00000.html>,
<http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00004.html>.
* NEWS (2.5): Update entry describing the dash extension to
grammar symbol names. Also, move that entry before the named
references entry because the latter mentions the former.
* doc/bison.texinfo (Symbol): Update documentation for symbol
names. As suggested by Paul Eggert, mention the effect of periods
and dashes on named references.
(Decl Summary): Update documentation for unquoted %define values,
which, as a side effect, can no longer start with dashes either.
* src/scan-code.l (id): Implement.
* src/scan-gram.l (id): Implement.
* tests/actions.at (Exotic Dollars): Extend test group to exercise
bug reported by Paul Hilfinger.
* tests/input.at (Symbols): Update test group, and extend to
exercise bug reported by Paul Eggert.
* tests/named-refs.at (Stray symbols in brackets): Update test
group.
($ or @ followed by . or -): Likewise.
* tests/regression.at (Invalid inputs): Likewise.
(cherry picked from commit 82f3355eaf)
* NEWS (2.5): Make some minor improvements to wording, and format
entries more consistently.
* doc/bison.texinfo (Language and Grammar): Point out that IELR
and canonical LR are experimental features.
(Decl Summary): In list of %define variables, make wording more
consistent. Improve discussion of using LALR for GLR.

Omit leading '/', since bootstrap omits it.
Adjust file names to match current contents better.

installed just for us.
* bootstrap.conf (excluded_files): Don't exclude codeset.m4,
glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now
needed somehow. Don't have time to look into why.
(gnulib_modules): Change malloc to malloc-gnu. Do we really assume
the GNU malloc behavior, where malloc (0) != NULL unless we're
out of storage? If not, we can omit malloc-gnu; but for now I left
it in to be safe.
(vc_ignore): Remove.
