GCC-3.2.2 pre-release (second iteration)

GCC-3.2.2 pre-release (second iteration)

[Gabriel Dos_Reis]

I uploaded 3.2.2 pre-release (second iteration) tarballs on the FTP
server as

     ftp://gcc.gnu.org/pub/gcc/snapshots/gcc-*3.2.2-20030129.*

As usual, please donwload and test them.  Report problems to me and
fill GNATS  PRs.

Unfortunately these tarballs are missing some RTEMS fixes.  They will
get in for the third (and hopefully final) iteration.

Thanks,

-- Gaby

I just tested on GNU/Linux, and I am seeing new failures since yesterday's
tarball (yesterday I had no unexpected gcc or g++ failures, and now
there are a total of 11, from 5 distinct tests).  See

http://gcc.gnu.org/ml/gcc-testresults/2003-01/msg01306.html

It's an "up2date" Red Hat 7.2 box with binutils-2.13.1.

Could someone else run the tests and try to verify this?

Numbers from 

  http://gcc.gnu.org/ml/gcc-testresults/2003-01/msg01325.html

are indicating something different -- which puzzles me.  
I just ran a full bootstrap + regression testsuite and saw two
failures related to C99 format specifiers on en i868-pc-linux-gnu.

I'm bootstrapping on another host.  

I'll keep you informed as things evolve.

Joe, Paolo --

I'm also seeing those failures with the tarball I uploaded but not 
on current version of gcc-3_2-branch (which will be the next
iteration).  

I looked into the failures and cannot find out which patches could
have possibly caused those failures.  All failures seem to be
"syntax error".  I'm inclined to conlude that the environment I used
to prepare the second iteration (which is at work) might be insane [it
is the one which started the reduce/reduce conflit thread]. 

I would like you run the testsuite again but for current CVS
gcc-3_2-branch and report the results.  Thank you very much for your
time.

Hi Gaby!

Everything is clear, now. I'm still seeing those spurious regressions, 
to wit

but they are *all* due to the Bison version I'm using: the very same issue
("parse error" -> "syntax error") that a few days ago led me to propose a
patch for mainline. For some reason, the current 3.2.2 branch when fed the
C testsuite triggers few more new posix "syntax error" from the 
Bison-generated
parser than mainline (and also some C++ ones which, of course are not 
relevant
for mainline). For instance:

I've been having trouble with subversions.gnu.org's CVS server today;
"cvs update" hangs indefinitely halfway through.  After repeated attempts
I think I have a 3_2_branch copy that is caught up, but I cannot
get contrib/gcc_update to complete.  I've never had this difficulty
before.

Any ideas?

Thank you very much for this detailed analysis.  I also accpet you offer.
That will make it possible for me to look at other queued patches.

Since we're in the same timezone, I understand what you're going to do
now and I guess you understand what I would like to do now (but it is
too late ;-).

Gabriel, just a heads up. the tarball does indeed appear to be broken.

Building from the tarball shows the failures whereas building from CVS is
fine for me:-

tarball:
http://gcc.gnu.org/ml/gcc-testresults/2003-01/msg01382.html

CVS:
http://gcc.gnu.org/ml/gcc-testresults/2003-01/msg01325.html


It is probably the bison thing as Paolo suggested. But I thought the
maintainer scripts were supposed to adjust the timestamps so as not to rely
on the bison in the user's environment. Dunno.

In that case, run

contrib/gcc_update --touch

before making tarballs.  This will update the times of dependent files
to be newer than those that are depended on (I'm not certain if it
gets everything, but it can't hurt).

Just one more piece of info for you:-


tarball:
gcc/c-parse.c  says   /* A Bison parser, made by GNU Bison 1.875.  */

CVS
gcc/c-parse-c  says   /* A Bison parser, made from c-parse.y
                         by GNU bison 1.35.  */


I have bison 1.75 installed on my system, In other words, when I compile from
CVS, gcc/c-parse.c is not being regenerated (like I would expect). The
gcc_update script is adjusting the timestamps for the generated files for
me. I wonder why this is not true for your build environment?

That i probably because I wasn't running gcc_update as suggested by

The maintainer scripts work fine.  The tarballs generated by the release
script include Bison-generated files generated by the person who ran the
script; when a user builds the tarball, the version of Bison they have is
irrelevant as the timestamps are correct.  When building from CVS, the
user's Bison version is relevant - but the Bison-generated files will only
be regenerated when the source file changes in CVS, not when you upgrade
Bison if the source file doesn't change.  Bison-generated files do not go
in CVS.

The release script already runs contrib/gcc_update --touch.

Just a guess: you applied a patch that modified a parser, then you did a
build to test it.  This build picked up your version of bison.
contrib/gcc_update --touch only does a touch.

They didn't.  gcc_update --touch has nothing to do with Bison generated
files since they're not in CVS and gcc_update deals with files in CVS; the
timestamps on Bison-generated files are correct by virtue of being
generated in a build after the tree has been checked out and gcc_update
--touch run.  The only thing that could be considered "wrong" is having
Bison 1.875 installed when generating the prerelease, which necessitates
the "syntax error" testsuite changes, rather than an older version that's
been tested for longer with the 3.2 series (e.g., whatever version was
used for the 3.2.1 release).

Firstly, there is no way I could have known that GCC's testsuite will be
affected by recent version of Bison as there is no mention of which
Bison should be used for GCC (pre)releases.

Secondly, I used my office environment -- not because I wanted to be

It's a good thing that you discovered this, actually.

Others won't know this either, so it will be a good thing to fix the tests
so that they won't be broken if they see "syntax error" instead of "parse
error".
