The initial location might be used if the parser starts by an empty
reduction, so really ensure proper initialization of the initial
location. The previous approach fails for PostgreSQL, which uses

With help from Théophile Ranquet.
* data/yacc.c (b4_declare_scanner_communication_variables): Be sure
to initialize yylloc, even when its structure is unknown.
(yyparse): Simplify the call to b4_dollar_pushdef.
* tests/actions.at (Initial location): Check of similar pattern
as in the case of PostgreSQL.
* origin/maint:
tests: close files in glr-regression
xml: match DOT output and xml2dot.xsl processing
xml: factor xslt space template
graph: fix a memory leak
xml: documentation
output: capitalize State
Make the DOT produced by XSLT processing equivalent to the one made with the
--graph option.
* data/xslt/xml2dot.xsl: Stylistic changes, and add support for reductions.
* doc/bison.texi (Xml): Update.
* src/graphviz.c (conclude_red): Minor stylistic changes to DOT internals.
(output_red): Swap enabled and disabled reductions output, for coherence
with XSLT output.
* src/print_graph.c (print_core): Minor stylistic change to States' output.
(print_actions): Swap order of output for reductions and transitions.
* tests/local.at (AT_BISON_CHECK_XML): Ignore differences in order.
* tests/output.at: Adjust to changes in DOT internals.
The XML output combined with the XSL Transformations provided in data/ are
incredibly useful, they should be documented.
* doc/bison.texi (Xml): New node.
* origin/maint:
maint: address syntax-check errors.
tests: use valgrind where appropriate

translated.
* doc/bison.texi: Fix incorrect @pxref use.
* po/POTFILES.in: Add missing file.
* src/print_graph.c: Remove useless include.
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.

While at it, run it only once, on all the generated headers.
Adjust to YY_NULL be defined in position.hh.

Running "maintainer-release-check" on OS X with Clang 2.9 fails,

(AT_QUELL_VALGRIND): Skip tests that cannot work because of compilers

do it.
Use a $printer.
Change some testing input to be easier to distinguish (instead of always
"0 0" for instance).
There are several issues to address here. One is that yylloc should
be initialized when possible. Another is that the push parser needs
to update yypushed_loc when the user modified it. And if the parser
starts by a reduction of an empty, it uses the first location on the
stack, which, therefore, must also be initialized to this initial
location.
This is getting complex, especially since because initializing a
global (impure interface) is different from initializing a local
variable. To simplify, the local yylloc is not initialized during its
definition.
* data/c.m4 (b4_yyloc_default_define): Replace by...
(b4_yyloc_default): this.
Adjust dependencies.
* data/glr.cc: Initialize yylloc.
* data/yacc.c (b4_declare_scanner_communication_variables):
Initialize yylloc during its definition.
Don't define yyloc_default.
(yypush_parse): The location formal is not const, as we might
initialize it.
(yyparse): Define yyloc_default.
Use it before running the user initial action.
Possibly update the first location on the stack, and the pushed
location after the user initial action.
* tests/actions.at (Initial locations): Check that the initial
location is correct.
* data/c.m4 (b4_yy_location_print_define): New.
Now issues "short" locations, e.g., "1.1" instead of "1.1-1.1".
Was initially a function, but then we face "static but unused"
warnings.
Simpler as a macro.
* tests/local.at, data/glr.c, data/yacc.c: Use it instead of duplicating.
* tests/actions.at: Adjust expectations.
* data/yacc.c: Fuse the initializations of yyssp, yyss and the like.
Remove an obsolete comment: we do initialize these initial stack
members (in some cases).
