Patches from Redhat gcc 3.2

Patches from Redhat gcc 3.2

[Alan Willis]

  Which of the 69 patches in the redhat gcc-3.2 rpm from RH8 provide the
functionality needed for the __thread keyword, and anything else needed for
nptl to work correctly.  Also, are any modifications needed to glibc 2.3?
Also, I do not wish to make my system unusable with 2.4.x kernels,.. if I
build glibc with --enable-kernel=current, will that make glibc unusable with
2.4.x kernels?  I've been using 2.5 for a while now,. but I do want a sane
recourse.  Is this line also correct: --enable-addons=nptl,nptl_db, where
I've untarred the nptl dirs under in the main glibc directory.

   I'm trying to set up an environment where I can use nptl on gentoo.

Any assistance is most welcome :o)

Thanks in advance,

I usually say what glibc version you need in the announcement.  The
stock 2.3 was fine for 03.  The next code drop will need more changes
which aren't in an official release yet.  For the time being you should
consider the CVS head as always working.  That's what I'm using internally.

You mean you are building glibc on a system running 2.5?  That certainly
makes the glibc unusable on 2.4 systems.  It's the purpose of the whole
exercise.

How we will handle this in the end is another question.  ld.so already
has some functionality which can help and that's probably what we will use.

Never mentioned nptl_db in this context.  It's included automatically if
nptl is named.

I am using glibc 2.3 compiled with gcc 3.2, and no problems at all.
Just pay atention to your binutils version if you want prelinking.
Well, due to some changes in glibc I was unable to run binary statically
linked against glibc 2.2.X, so I had to recompile root bash...

The ones with "tls" in the title.  There were at least 5 the last time
I checked.  Alternaltly, check out either gcc-3_2-rhl8-branch or mainline
from gcc.gnu.org.

Cool, I think I'll wait for 2.3.1.

I suspected as much but I wanted to be sure.

Thank you Roland.  I will probably end up installing RH8 anyway, for the
patches to gcc.  Do binutils need to be rebuilt / linked against glibc?
I doubt it, but I figure it's better to just ask.
