egcs cvs'd between 980214 8:00 and 9:13 UTC on m68k-next-nextstep3:Success

[Toon Moene]

I managed to cvs -z 9 co egcs yesterday 980214 between 9 and 10:13  
local time (UTC + 1).

The subsequent build succeeded without major complaints, although  
of course the new -W -Wall options gave rise to a lot of warnings.

Running c-torture-1.45 showed one test failure to be eliminated  
with respect to the previous snapshot I built (980129):

Now I want to do the same with the 1.0.2 release branch - what -r  
tag do I specify for that ?

Cheers,

Cool.  You'll probably find that subsequent updates will run much
faster than the initial checkout :-)

Yup.  I squashed another handful, and, with so many folks fixing
them, I suspect we'll have it down to managable size relatively
quickly.

I have 8 patches for egcs 1.0.2. I have sent 3 of them, which have
yet to be acked. Should I send my other 5 or should I wait for
the backlog to be cleared first?

Thanks.

Please wait for the backlog to clear.

Also, are this *critical* patches?  Some of the stuff I've seen go
by look more complex than I would prefer for 1.0.2.

One of them is definitely critical. egcs 1.0.1 is broken on x86 at
least with long double. I don't know what else is not working
right. Basically egcs 1.0.1 turns

if (exp1 && exp2)

into

if (exp1)

under certain conditions. As for others, they make it to work on glibc
2.1 and fix some libstdc++ bugs.

BTW, most of them are already in the main trunk. Only 2 patches are
new.

Thanks.

I'd hesitate to call a long double bug critical -- few folks use
long double on a regular basis.

I cannot use egcs 1.0.x to compile glibc 2 since it uses long double
in many places. That is how I noticed the bug. It is hard to convince
anyone to use egcs 1.0.x if they want to use glibc 2, who happen to
be Debian, RedHat and SUSE.

I gather that there is controversy about spending a lot of effort to
fix "long double" in a minor release.  I would think that if these
changes will not affect code that does not use long double they will
at least do no harm, and not being able to build glibc does make us
look bad.

Here is the patch I have been talking about. It was installed
in egcs evev before egcs 1.0.1 was released.

You are twice wrong: the patch below doesn't match the ChangeLog entry, and
the patch that goes with the ChangeLog entry was installed in egcs-1.0.1.

I was wrong. Sorry for that. I was very frustrated since egcs 1.0.1
miscocmpiled glibc 2. It appears that the patch really came from

I apologize for having sent that patch to Kenner only, not to this list.

egcs-1.0.1 has a bug which wasn't present in gcc-2.7.2.
A "testl $64,%eax" or "testb $64,-4(%ebp)" is omitted. This kind of bug
occurs in particular when DImode variables are used. Please find below
a problem report and a fix.

 Hm, as HJ said this affects all glibc2 users who try to compile it
 with egcs.... I don't know why but somehow it worked on my system...

The test cases were added in glibc 2.1. You might not noticed the bug.
But it is there. It is fixed in 1.0.2 now.

egcs-ers

I've just downloaded egcs1.0.2 and installed it on solaris2.5.1.  So
far I'm able to compile and install it and compile some code usings egcs.
I've compiled some of my own code + the STL test suite distributed by
MegaByte (STL adaption previously maintrained by Moscow Computing Center).

Before continuing, config.guess => sparc-sun-solars2.5.1

config command:
../configure --prefix=/fou/c4share/lib/egcs --enable-haifa \
             --program-prefix="egcs-" \
             --includedir=/fou/c4share/include/tcl7.5 \
             --includedir=/fou/c4share/lib/tk4.1

The includedir was added in an attempt to let the config command
find my local tcl & tk installation (without any success it seems :-( )

I should also say that I used native sun compilers (cc v4.2) and
gnumake v3.69, and I downloaded the whole installation, including
the dejagnu version you have provided.

There are however some issues I'd like to address

Build, Test & Install
=====================

     * make -k check didn't run any testsuites in the gcc area, and
       the only part being tested seems to be libio.  Anyway, the test
       completes after 4 min on an Ultra-30 which tells me that not very
       much has been tested.  Do these tests require a full install of
       dejagnu?  configure in dejagnu ended up with
       "... no X based programs will be installed."

     * there are a few compiler warnings, both when building stage1 using
       native sun cc, and when building stage{N} using stage{N-1}.

     * although I provided a program-prefix to configure, the programs
       installed still have the standard names (gcc, g++ etc), I'd expected
       egcs-gcc, egcs-g++ etc.

     * rtti - is there any reason why typeinfo.h is not shipped with egcs?
       I noticed that typeinfo.h was part of libg++2.7.2, but not in 2.8.x!!

FYI, I'm going to use egcs mostly to check for ANSI compliance in my own
code + experiment with recently added features since the other compilers
I'm using are lagging ANSI a bit more than you ...

"make check" from the toplevel should have run the testsuite in
the gcc directory.

Probably the first thing to do is for you to run running it within
the gcc directory yourself.  That may tell us why it failed to run
from the toplevel directory.

Yes.  We are working on these.

Known bug.  A patch (or even analysis) for the bug would be greatly
appreciated :-)

EGCS doesn't know anything about tcl/tk, so this isn't going to do anything
useful anways.

Dejagnu uses tcl/expect, but using your local copy is probably not a good
idea.  We know it works with the libraries included in the dejagnu package.
We don't know if it works with your local versions of the libraries.

     * make -k check didn't run any testsuites in the gcc area, and
       the only part being tested seems to be libio.  Anyway, the test
       completes after 4 min on an Ultra-30 which tells me that not very
       much has been tested.  Do these tests require a full install of
       dejagnu?  configure in dejagnu ended up with
       "... no X based programs will be installed."

What kind of output did you actually get?  I can't help if I have no idea
what output you got.  There probably is something wrong, but I have no idea
what.

You can ignore the dejagnu configure warning.  `make check' does not invoke
any X based programs, so the fact that they aren't built is not a problem.

     * there are a few compiler warnings, both when building stage1 using
       native sun cc, and when building stage{N} using stage{N-1}.

You can ignore the warnings.

In general, it may not be possible to make the source code warning free for
all possible compilers for all configurations.

We deliberately added -Wall to the stage2/stage3 builds to help find bugs,
and we are slowly in the process of adding patches to eliminate the gcc
warnings.

     * although I provided a program-prefix to configure, the programs
       installed still have the standard names (gcc, g++ etc), I'd expected
       egcs-gcc, egcs-g++ etc.

Offhand, I don't know.  I haven't tried using this option.

     * rtti - is there any reason why typeinfo.h is not shipped with egcs?
       I noticed that typeinfo.h was part of libg++2.7.2, but not in 2.8.x!!

I don't know.

Sigh.  It would be great if dejagnu could be verified to work with
standard tcl/expect installations, because these are installed standard in
most Linux distributions, most others have Tcl already, and it would
greatly cut down the size of the dejagnu distribution.  If you're worried
about errors, dejagnu can inquire about the Tcl and expect version on
startup and refuse to run, or warn, if an unverified version has been
detected.

Of course this requires a volunteer.

Use <typeinfo>, not <typeinfo.h>.

	Then I tried to run make -k check from the solaris2.5.1/gcc dir without any
	success.

What do you mean by no success?  Did you get an error?  What was that error?
You still haven't shown us any of the output from that `make -k check' command.
I'd need to see the output before I could comment on why it failed.
