[parisc-linux] HPPA NPTL Support committed to libc-ports, help needed!

[Carlos O'Donell]

parisc-linux,

I've committed a first cut NPTL port for hppa to libc-ports.
Please help build and test the port!

You will need:
binutils head cvs newer than 2006-05-24.
gcc cvs head newer than 2005-07-05 with TLS turned on.
libc-ports cvs head newer than 2006-07-14
glibc cvs head to match libc-ports.

I don't have a recipe for building this yet, but it should be coming next.
If someone wants to adapt the following file, that would be great:
http://cvs.parisc-linux.org/build-tools/build-tls-tools?rev=1.7&view=markup

In essence:
- Build binutils
- Install binutils
- Build gcc with tls on, and using previous binutils (i.e. set your PATH)
- Install gcc locally.
- Build glibc with --enable-addons=ports,nptl (Set your PATH to new
gcc/binutils)
- Run make, make -k check.

Start looking at failures :)

Cheers,
Carlos.

I have check to <http://buildd.debian.org/build.php?arch=hppa&pkg=gcc-4.1>

and afaik debian gcc-4.1 release >= 4.1.1-6 should be ok
(iirc no gcc configure option to build it with tls support but a check if used binutils supports it)

[snip]
bzip2: missing
binutils: already installed (2.17-1 >= 2.16.1cvs20051214 is satisfied)
binutils-hppa64: missing
[snip]

(still need to check if this pb:
<http://lists.parisc-linux.org/pipermail/parisc-linux/2006-May/029185.html>
is not any more in 4.1.1, i will advise?)

FWIW, I'm seeing the following FAILs with gcc head built with binutils 
head (from yesterday)

glibc built and running make check now..

GCC is slower than it used to be...

This is a known regression.  See
<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26244>.
