[parisc-linux] glibc-2.3.3: a warning with gcc-3.3 become an error with gcc-3.5

[Joel Soete]

Hi all,

As the title mail said, the following warning with gcc-3.3:
../sysdeps/hppa/fpu/feupdateenv.c: In function `feupdateenv':
../sysdeps/hppa/fpu/feupdateenv.c:31: warning: assignment of read-only member
`__status_word'

become an error with gcc-3.5:
../sysdeps/hppa/fpu/feupdateenv.c: In function `feupdateenv':
../sysdeps/hppa/fpu/feupdateenv.c:31: error: assignment of read-only member
`__status_word'
make[2]: *** [/Develop/parisc-linux/build/glibc/math/feupdateenv.o] Error
1
make[2]: Leaving directory `/Develop/parisc-linux/sources/glibc-2.3.3-20040301/math'
make[1]: *** [math/others] Error 2
make[1]: Leaving directory `/Develop/parisc-linux/sources/glibc-2.3.3-20040301'
make: *** [all] Error 2

And regarding the definition of feupdateenv():
int
feupdateenv (const fenv_t *envp)
[snip]

I couldn't blame gcc.

So I would suggest to use sysdeps/mips/fpu/feupdateenv.c as model:
int
feupdateenv (const fenv_t *envp)
{
  int temp;

  /* Save current exceptions.  */
  _FPU_GETCW (temp);
  temp &= FE_ALL_EXCEPT;

  /* Install new environment.  */
  fesetenv (envp);

  /* Raise the safed exception.  Incidently for us the implementation
     defined format of the values in objects of type fexcept_t is the
     same as the ones specified using the FE_* constants.  */
  feraiseexcept (temp);

  /* Success.  */
  return 0;
}

but replacing:
 * 'int temp;' by 'fenv_t *temp;'
 * '_FPU_GETCW (temp);' by 'fegetenv(temp);' (as we don't have _FPU_GETCW()
)

But not sure it's the best solution.

Thanks in advance for all advise,
    Joel

"saved exception" or "safe exception"?

Joel,

Could you lookup the C99 specification please?

This is required to set the flags. Please review the specfications.

AFAIK, this is not correct, the spec says that it will be an OR of the
raised exceptions, e.g. an OR of the raised flags. 

Calling feraiseexcept could fault the program.

Yeah, this is bad, because 'envp' is const, and we shouldn't be changing
its value.

Why do you use "new_env" at all? Just use saved_env. Then you don't have
to have a silly loop to copy the exceptions, they'll already be there.
Then you can call fesetenv(&saved_env);

The reason is very simple: I just begin with glibc and my knowledge is still at stone age in this field.
This is an evidence that sun appears red in the early morning or at the end of the evening but white for the rest of a suny day, why?
The same here, hppa don't need feraiseexcept() but the alpha, i386, ia64, m68k, mips, (ppc), s390 and sparc need and I don't yet 
understand why ;)

Because our feraiseexcept() is different from theirs?

Right now I reach to build glibc completely (with just a warning less ;) )
This c110 is unfortunately too slow to let me complete the make -k check now, I will so continue tomorrow ;)

[parisc-linux] [PATCH] glibc-2.3.3 error with debian unstable compiler...

That's a typo that *every* other arch has because they copied the code
from i386, I think rth was the only one anal enough to fix the spelling
mistake ;)

I snatched the C99 spec and fixed our implementation based on my reading
of the current code, other arch code, and the spec. The correct
feupdateenv is provided below.

I'm sending this upstream to debian, so we can build again.

Carlos,

I just apply your patch against the glibc cvs dated 20040405 (yesterday for
me).
It compiles well with last updated gcc (3.3.3-6 dpkg iirc) :)

I just complete the 'make -k check' (on chroot disk) which finished with
nothing more then well known bug :)

... And the compile (always in the chroot disk) of the last k-2.6.5-pa3 just
finishes with success :)

hth,
    Joel

Carlos,

Last week I encounter some pb to co last cvs, sorry.

This week and can apply your patch against the glibc cvs dated 20040419 (just
some hunk failled because in the uptream: great).

I just complete the 'make -k check' (on chroot disk) which finished with
just one more error then well known ones:
make[2]: *** [/Develop/parisc-linux/build/glibc/stdio-common/tst-rndseek.out]
Error 1
make[1]: *** [stdio-common/tests] Error 2

... And the compile (always in the chroot disk) of the last k-2.6.6-rc1-pa0
works still fine and even boot well on a b180.

hth,
    Joel

I'm seeing an extra error with realtime signal delivery tst-timer4, but
not this error. I'm working on fixing tst-timer4, can you find out why
tst-rndseek fails?

What does tst-rndseek.out say? I don't see this error?

Cheers,
Carlos.

Yes, the default timeout is too short, add a TIMEOUTFACTOR of 5 or more.

Re: [parisc-linux] RE: [PATCH] glibc-2.3.3 error with debian unstable compiler...

[Joel Soete]

Hello Carlos,

Here is my weekly test: cvs 20040426.
Nothing new to mention: always well known errors collected after make -k
check. I just build a 2.6.6-_rc2_-pa2 (for the fun) without pb (which boot
fine on my b180)

Cheers,
    Joel

PS: 
> Yes, the default timeout is too short, add a TIMEOUTFACTOR of 5 or more.

This time I put TIMEOUTFACTOR=4 in the chroot root profile and seems to be
enough to bypass timeout errors :)

You aren't seeing a failure in tst-timer4?
Can you verify this by running tst-timer4 by hand and sending the output
ot the list?

c.

Re: [parisc-linux] RE: [PATCH] glibc-2.3.3 error with debian unstable compiler...

[Joel Soete]

> You aren't seeing a failure in tst-timer4?

uhm ... No (definitely :^)

> Can you verify this by running tst-timer4 by hand and sending the output
> ot the list?
Yes naturally, here there are:

# ./tst-timer4 
clock_gettime returned timespec = { 1083087449, 554351000 }
clock_getres returned timespec = { 0, 10000000 }
# echo $?
0

Well duno if results are right (first line different on each test but the
second is constant with or without TIMEOUTFACTOR)?

Don't hesitate with more questions ;)

Okay, it's a 64-bit kernel problem them. What kernel are you running
right now?

a merged 2.6.6-rc1-pa2 and upstream 2.6.6-rc2 :) 32bits build with lastest
gcc-3.3, binutils (debian unstable) and libc6 (cvs 20040426 + your patches
:)

I also have a b2k on which I can try to build 64bits kernel with gcc-3.0?

Certainly: I just rebuild my own merge of 2.6.6-rc1-pa6 and 2.6.6-rc3 with
gcc-hppa64 (from ftp.p-l.org) and reboot my b2k with it and effectively the
result of tst-timer4 is a bit different:
# ./tst-timer4
clock_gettime returned timespec = { 1083142973, 718981000 }
clock_getres returned timespec = { 0, 10000000 }
*** sig1_sigval.sival_ptr (nil) != 0xbff00690
*** sig2_sigval.sival_ptr 0 != 163
# echo $?
0

It does help, we have a padding problem in siginfo, I never had enough
test cases to prove the __SI_RT parts were in the right place. This goes
to show that what you can't test is probably wrong.

I have to work on this today...

I trust it is not related but btw I encounter another strange pb with this
kernel:
I launch a find on a big disk and get severall messages:
find: /a/dir/of/mine: Input/Output error
...

the same when ls -l /a/dir/of/mine (I/O error)

well this is a merge of our 2.6.6-rc1-pa6 and upsteam 2.6.6-rc3 64bits.
if i reboot with 2.6.6-rc1-pa0 32bits no pb.

So i will try to rebuild 2.6.6-rc1-pa6 alone in 64bit and see if the pb is
there or in my merge?

Cheers,
    Joel

Well,

That must be something wrong in my merge 2.6.6-rc1-pa6 works fine. I will
wait the p-l merge.
