14 years agoAdjust to recent changes to gnulib bootstrap.
Paul Eggert [Fri, 8 Oct 2010 18:10:06 +0000 (11:10 -0700)] 
Adjust to recent changes to gnulib bootstrap.

* .cvsignore, build-aux/.cvsignore, doc/.cvsignore, etc/.cvsignore:
* examples/calc++/.cvsignore, lib/.cvsignore, m4/.cvsignore:
* po/.cvsignore, runtime-po/.cvsignore, src/.cvsignore:
* tests/.cvsignore: Remove; I don't use CVS to maintain Bison
anymore and don't know of anybody else who does.  If someone needs
these files, they can resurrect them.
* .gitignore, build-aux/.gitignore, doc/.gitignore, lib/.gitignore:
* m4/.gitignore, po/.gitignore, runtime-po/.gitignore:
Omit leading '/', since bootstrap omits it.
Adjust file names to match current contents better.
* bootstrap: Sync from gnulib: this contains the new gnulib_mk_hook
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.
* README-hacking: Renamed from HACKING, since gnulib bootstrap now
uses that convention.

M4's output pipe was not being drained upon fatal errors during

on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a

where the default disposition for SIGPIPE is ignore instead of
terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
then reported it.  However, there's some sort of race condition,

15 years agoFix handling of yychar manipulation in user semantic actions.

Fix handling of yychar manipulation in user semantic actions.

The problem was that yacc.c didn't always update the yychar
translation afterwards.  However, other skeletons appear to be
fine.  glr.c appears to already translate yychar before every
use.  lalr1.cc does not define yychar and does not document its
replacement, yyla, for users.  It does provide yyclearin, but
that does not manipulate yyla and thus requires no translation
update.  In lalr1.java, yychar is out of scope during semantic
actions.
* NEWS (2.5): Document.
* data/yacc.c (YYBACKUP): Don't bother translating yychar into
yytoken here.

yytoken, and add comments explaining this approach.
* tests/actions.at (Destroying lookahead assigned by semantic
action): New test group checking that translation happens before
lookahead destructor calls at parser return.  Previously,
incorrect destructors were called.
* tests/conflicts.at (%error-verbose and consistent
errors): New test group checking that translation happens at
syntax error detection before the associated verbose error
message and the associated lookahead destructor calls.  While
the destructor call is fixed by this patch, the verbose error
message is currently incorrect due to another bug (see
comments in test group), so this is an expected failure for now.
