[Bug fortran/33271] nint_2.f90 abort compiled with -O0
--- Comment #5 from michelin60 at gmail dot com 2007-09-03 13:49 ---
(gcc a.c -lm -W -Wall; try with -O0 and -O1, I expect it will fail only at
-O0).
One last question: in your build tree, you should have a file named
${builddir}/${target_triplet}/libgfortran/config.h. How does it define the
macros HAVE_LLROUND, HAVE_LLROUNDF, HAVE_LLROUNDL, HAVE_LROUND, HAVE_LROUNDF
and HAVE_LROUNDL?
Let me start off by saying that today is a holiday and that tomoorow I am back
at work and traveling, I am not allowed to use __any__ business assets for GCC
connected activity.
That last question seems beyond my ken. I am running glibc-2.6.1
(the latest official). The GCC tree is just the fairly current svn without any
changes by myself. I am a chemical engineer and computers, compilers are just
tools as far as I am concerned. I certainly do not use the latest for
production work (I have about a dozen compilers that I can make active at any
given time. This is my home machine and completely disconnected from my
company.
We just had an extensive power outage and we just recovering. I will try and
run that program today? the question is with which C compiler ( the latest
Trunk, gcc-4.3.0? 4.1.current? 3.3.6 ? or 3.4.6? and even the junky 4.2.1) I am
not prepared to give you a choice of glibc as going back to earlier versions is
generally discouraged and rather risky.
Regarding the last question just look in your own current svn tree.
You might also look at PR33271 or PR33277 for my latest fiasco with Pinski. He
appears to owe his job to Dr. Edelsohn and was just hanging around a school
where a relative is a department head for several years. (this is documentable)
Do not try to recruit me as a maintainer because I would __never__ consider
working in an organization as politiized and poorly run as GCC. Mark Mitchel is
just not allowed to act as a real release manager.
The exception is the fortran group (minus Kargl). Where Paul Thomas has been
doing herculean work. I would love to see at least part of that work in 4.1.x
as 4.2.x and 4.3.x are completely messed up with things like decimal float
(major marketing tool of IBM). By the way the latest gcc on AIX is 3.3.1. Thus,
the IBM marketing types are pratically stating that they want to see gcc-4
hobbled.
Now if you do not want to work with me any more, just let me know. I am am
pretty hard boiled from the US corporate world and can spot the gcc
manipulations from a mile away.

[Bug middle-end/33277] [4.3 Regression] Bootstrap check failures ICE's
--- Comment #5 from michelin60 at gmail dot com 2007-09-02 15:23 --- I am beginning to enjoy this: There are about 34 hours between the first indication of failure on regress an my report. There are about 8 hours between my report and the first acknowledgment by GCC. This came by master of obfuscation and arbitrariness: Mr Pinski. The management motto at GCC seems to be: Do as I say, do not do as I do There is one person on the steering committee, who has real experience in building and managing a grou of professionals. His name is Mark Mitchell of Codesourcery. There is another member, acting as chairman, who is decidedly mis-using GCC for the interest of one company. His name is Dr. Edelsohn of IBM. This is not my statement I posted, acknowledged by GGC, proof in an earlier posting PR3316. That posting caused Mr. Pinski to flaunt a few more rules of comity, ownership of intellectual property (the posting), etc. There is ample confirmation provided for this misuse of GCC by using Google to for Scott Handy IBM. Mr Handy is pretty far up in IBM management. Well as long as my name appears as poster of reporter I reserve the right to say whatever I please within the rules governing defamation and avoidance of foul language like used habitually by Mr. Pinski. -- michelin60 at gmail dot com changed: What|Removed |Added CC||dje at watson dot ibm dot ||com, mark at codesourcery ||dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33277
[Bug middle-end/33283] [4.3 Regression] gcc.c-torture/execute/930921-1.c fails at -O1 and above now
--- Comment #3 from michelin60 at gmail dot com 2007-09-02 18:57 ---
Well here it is for interfering with Mr Guenther doing the reasonable thing.
This arbitrariness and unwarranted interference led me to do this.
It is also interesting to look a the GCC.mailing.list for June and July to
realize what is really going on within GCC
Mr. Mark Mitchell was overruled on his misgivings regarding the status of
gcc-4.2.0 . Hence gcc-4.2.0 is not really serviceable and can not even compile
glibc on some architectures. The linux distributors are staying away from
gcc-4.2.0 save for SUSE. However, SUSE made it impossible to find out
readily which gcc version compiled their executables and libraries. Thus a
statement that their latest available beta or release candidate compiler is
gcc-4.2.x is not verifiable.
What follows is a verbatim copy of PR33271 tentatively suppressed by Mr.
Pinski, who appears to be a protege of Dr. Edelsohn.
The summary results are pretty obvious:
FAIL: gcc.c-torture/execute/930921-1.c compilation, -O1 (internal compiler

There is only on category, namely rs6000, both in the config tree and in the
MAINTAINERS LIST, so do expect the submitters to devine any other name dujour.
Also if the supposedly scarce manpower available can process hundreds of
pretty irrelevant GPL3 and whitespace elimination patches ( even for an already
released 4.2.x series) then submitters should not be harassed about submitting
superfluous details.
GPL3 has been dismissed by the world. Just look at the trade press, slashdot,
dig, and others.
There is neither adequate management for the steering committee down nor other
than lip-service to quality control. This and recent submissions by the
Debian-gcc-team prove the point.

--- Comment #14 from michelin60 at gmail dot com 2007-08-31 14:52 ---
FAIL: gfortran.dg/nint_2.f90 -O0 execution test
This one is annoying, I think I had it fixed (I saw it on numerous targets, and
fixed it on most... I believed it was fixed on all targets). If you are willing
to get this fixed, please open a PR specifically for this problem, adding the
relevant output from ${builddir}/gcc/testsuite/gfortran/gfortran.log.
Additionally, you might want to compile and run the testcase outside of the
testsuite framework, see what happens and put that into the bugreport.
Hopefully, I can work on fixing that with you (asking you to perform any
further inquiries).
PS: most developers of gfortran are also end-users of the compiler, and
volunteers. Most of us are academic or private researchers. Writing this long
explanation took 30 minutes of my working day, and thus impacted my own
resarch, so please consider it seriously. (I also am a working in physical
chemistry, have a few friends working with Michelin.)
Thank you for your detailed and informative response. Glad to work with sombody
in the physical sciences. I was/am not smart enough to get into physical
chemistry. My family background is Northern Italy and any connection to the
French branch must have occurred centuries ago.
Let us start with the easiest one for me as this is the last working day of my
vacation, I cannot give access to to my dual G4 machine as my Internet
connection does not allow outside initiated connection. I will immediately
gather data on nint_2.f90 and open an PR.
Thanks again

Could you compile with -O0 -fdump-tree-original and attach the
nint_3.f90.003t.original file (or similarly named)? Could you also run with
-O1 -fdump-tree-optimized and attach nint_3.f90.115t.optimized (or similarly
named)?
No problem but some questions:
A) I see that you and others put a number of patches and regenerations. Do you
want me to rebootstrap and then do it? If an earlier version is acceptable do
you want using the test command as amended per above can I do outside of the
gcc tree?
If outside the tree I can do it right now. I also hope that the attachment
process works again. personally I had no problems until PR33252. I presume you
are in Europe with a 6 hour time difference.
I will do it on nint_2.f90 right now to try the attachment nint_3.f90 migh have
been a slip on your part. They are small thus not attached.

--- Comment #6 from michelin60 at gmail dot com 2007-08-31 01:43 --- (In reply to comment #5) First off don't CC anyone unless there is a real reason to like you know they caused the issue. Second most of the rest of the failures are PR 33225 anyways. First of all I CC'd Dr. Edelsohn because I mentioned him and he was the acting on PR33168, you chimed in about 24 hours later. Even you mention somebody involved by name it is common curtesy to make that person aware of that mention. Second I mentioned Mark Mitchell because he, as relesae manager, put a stop to backporting definitely aggravating productive use of GCC. Third you mentioning PR33168 out of context instead of PR33225 was just plain dumb so I CC'd Burnus because he seems to be working pretty hard to make gfortran usable. Last but not least, there are even two ICE's (mayalias) in the test results that I did not feel making an issue of. Result, do not force me to contact these people directly when you do not take the pain of even reading submissions. -- michelin60 at gmail dot com changed: What|Removed |Added CC||dje at watson dot ibm dot ||com, mark at codesourcery ||dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33252
[Bug fortran/33252] GCC-4.3.0 Bootstrap testsuite error increase
--- Comment #10 from michelin60 at gmail dot com 2007-08-31 04:33 --- (In reply to comment #7) Subject: Re: GCC-4.3.0 Bootstrap testsuite error increase Second I mentioned Mark Mitchell because he, as relesae manager, put a stop to backporting definitely aggravating productive use of GCC. This is the trunk we are talking about, I am seriously thinking you need to understand what that means. There is no backporting, it is And again, this is the trunk we are talking about, not some release branch and we are not even in stage 3 yet so there will be issues. It was just fixed so update and try again. Yes we know about those, if did a quick search, you would find that I filed the bug about those before I added those testcase. Regarding the last quote I am led to believe that Mr. Pinski is taking undue credit. PR30758 (marked as a duplicate) is the first addressing the re-appearance of mayalias. there are another 5 PR, all appearing before Mr. Pinski's filing. This reminds me of what happened regarding PR33125 (filed by myself) and PR33126. Neither made to the bug list; neither has been officially closed. Anyhow the patch submitted seems to have resolved the issue. I updated, and I am now bootstrapping with check. I am sure Mr Delisle patch originally worked and passed tests; but, that some other later patch gave rise to what I, and seemingly others, saw in PR33252. I took issue with Mr. Pinski's confusing PR32225 with PR33125 not Mr Delisle volunteer work. Now to the more confusing issue of backporting. I managed to find the following: IMO, for the Fortran front end, regressions-only is an inappropriate criterion for this sort of mode, given that the front end does not have a long history for the wrong-code and ICE-on-valid bugs to be regressions against. I think that's less true than it used to be. It's true that gfortran is new-ish, and I've given the Fortran team a lot of flexibility in past release cycles. But, congratulations are in order: gfortran is now a real Fortran compiler and people really are using it! But, regressions, wrong-code, and ICEs isn't a bad criteria for this intermediate lockdown. I do expect Fortran to honor the regressions-only rule once the 4.3 release branch has been made. Thanks, -- Mark Mitchell CodeSourcery [EMAIL PROTECTED] Mr Kargl explains what happened from an maintainer's and release manager's view but does not provide a paliative to the user. G77 relative to g90 is relatively much more out of date than C1989 to C1994. Anyhow, if memory serves, there was significant back-porting from 4.3 to 4.2.x to to solve some memory usage problems.

You submitted the bug. Let the GCC developers decide how best to triage and analyse the bug. David Well David here is an interesting quote: IMO the most notorious case is how the gcc development is held hostage by Edelsohn and maybe IBM as a whole by requesting that everything always works perfectly well on AIX. How often has one seen this patch breaks AIX, back it out. It cannot reasonably be expected that everybody tests on AIX. It is an proprietary OS running on proprietary and expensive hardware which not many people have access to. The overall development speed could be significantly improved by dropping the AIX requirement which, in some form or another, has been agreed upon by the steering committee. AIX is irrelevant in general today, i.e., the situation changed. And the people in the steering committee are too nice to just tell the very small minority causing the problem to take a hike. --- Comment #7 From Andrew Pinski 2007-07-23 18:42 [reply] --- (In reply to comment #6) Well David here is an interesting quote: Lets put it this way, this quote is true but it is held hostage in a good way. You don't want broken code in your compiler do you? This is what David and AIX does for GCC, they prevent bad code from being in GCC. Have you looked into what has been found via compiling on AIX? Lots of bugs. Who wants bugs in their compiler? Anyways as I have mentioned before, I am 99% sure this is ___NOT___ related to the powerpc back-end at all. And next time please don't CC anyone unless you are sure at what patch caused the issue. Also don't you can't expect a response within 24 hours, GCC developers are busy with their day jobs. --- Comment #8 From Andrew Pinski 2007-07-23 18:56 [reply] --- Working on a reduced testcase but when I quickly looked into it, PRE was messing up the variables that have abnormal set so this is unrelated to the rs6000 back-end. --- Comment #9 From Andrew Pinski 2007-07-23 21:31 [reply

--- Comment #11 from michelin60 at gmail dot com 2007-07-23 23:17 --- Very interesting Using a colleague's i686 machine vfprintf.c did not fail with recent gcc-4.3. This led to further research prompting not only the CC's but also the quote. Dr. Edelsohn metioned triage but there are no triage officers in the MAINTERNER list. Also it might be useful to spell out the rights of submitters. It might discourage submissions which are quite onerous to conform to the already stated requirements. From his webpage Mr. Berlin is a lawyer specializing in intellectual property and is also an author. He might want to provide some legal advice on conflicts of interest. The quote is specific to glibc and AIX. Potentially the AIX contortions forced upon glibc by Dr. Edelsohn could have caused the specific problem reported, not affecting i686. As an aside the officers of kernel.org (Torvalds, Morton) spell out quite clearly how they are not liable to any interpretation of conflict of interest. -- michelin60 at gmail dot com changed: What|Removed |Added CC||dje at watson dot ibm dot ||com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32865
