[parisc-linux] Glibc 2.3.2 failures and possible fixes?

[parisc-linux] Glibc 2.3.2 failures and possible fixes?

[Carlos O'Donell]

John, Tausq,

Succeeded in building glibc 2.3.2 with syscall cancellation support, but
I'm pretty sure it's wrong.

The current list of failures includes:

iconvdata/bug-iconv3.out

- This is a new one.

math/test-fenv.out
math/test-float.out
math/test-double.out
math/test-ifloat.out

- We've had the math test failures for a while, would you like it if I
  tried building glibc with gcc head? It's been so long I've forgotten
  if this was really the delayed fp stuff that I fogot to implement :}
  Will get around to testing this more near the end of April.

stdlib/tst-strtod.out
stdlib/bug-strtod.out

- These are not so new, but indicate problems.

libio/tst-mmap-eofsync.out
libio/tst-mmap-fflushsync.out

- New kernel with Tausq's mmap flushing changes should make these go
  away... have to go into the office to install a new kernel.

dlfcn/default.out
dlfcn/tststatic.out

- New, possibly related to syscalls.

posix/annexc.out

- Expected.

linuxthreads/ex8.out
linuxthreads/ecmutex.out
linuxthreads/ex14.out
linuxthreads/ex15.out
linuxthreads/bug-sleep.out
linuxthreads/tst-cancel1.out
linuxthreads/tst-cancel2.out
linuxthreads/tst-cancel3.out
linuxthreads/tst-cancel4.out
linuxthreads/tst-cancel5.out
linuxthreads/tst-cancel6.out
linuxthreads/tst-popen.out
linuxthreads/tst-popen2.out
linuxthreads/tst-cancel-static.out
linuxthreads/tst-cancel-wrappers.out
rt/tst-shm.out
rt/tst-clock.out
rt/tst-aio.out
rt/tst-aio64.out
rt/tst-aio2.out
rt/tst-aio3.out
rt/tst-aio4.out
rt/tst-aio5.out
rt/tst-aio6.out
rt/tst-aio7.out

- I broke a lot of stuff... :}

elf/vismain.out
elf/neededtest.out
elf/neededtest2.out
elf/neededtest3.out
elf/neededtest4.out
elf/circleload1.out

- These have been around for a while, any idea about how to fix them?

Cheers,
Carlos.

I think this is the mismatch in sizeof(long double) problem again.

They've certainly been around since I was hacking on glibc ...

I am less luky.

I grab src of glibc-2.3.2 from ftp.gnu and aply your patches and try to rebuild
on an unstable debian (update this 20030324).

unfortunately I got the following err:

I also find:

                           Elf32_Addr *const reloc_addr)

Thanks for advise,
    Joel

I noticed that a couple of libstdc++ tests that used to fail because
of the long double mismatch are fixed with 2.3.1-14 :)

Are you testing with 3.3?  Some elf tests in the binutils suite
were failing because of the need to canonicalize function pointers.
There were also some tests that failed because we absolutely need
'-fPIC' for tests with shared libraries.  I'd be interested to know
what's causing these.

Really? I didn't even put in patches for -14? :) This is all strictly
from upstream glibc.

I can rebuild it using 3.3 and see if this goes away. Right now I'm
building with 3.2.3. I sure hope getting rid of these is as easy as
building with 3.3!

On a second note, I've completely revamped the sysdep-cancel support
since I must have been smoking crack when I wrote it... so I'm going to
compile another round that should come out much better (hopefully
removing all the linuxthread failures).

Thanks for the feedback!

Missing patch. My bad. 
I'll update in a few hours with a new sysdep-cancel patch.

Thanks for testing Joel!

Don't worry.

I will waiting for :)

You know how much am i interested. I know my knowledge is limited but I try
to do my best. 

Always wellcome and thanks for your attention,

[parisc-linux] glibc 2.3.2 patches updated, still no working sysdep-cancel

[Carlos O'Donell]

>I'll update in a few hours with a new sysdep-cancel patch.

Patches updated:
http://www.baldric.uwo.ca/~carlos/glibc-2.3.2-patches.tar.gz

Still no luck on getting sysdep-cancel to work. I'll need another pair
of eyes to look at the assembly in sysdep-cancel.h
