Where can I get gcc-ia64 updates? I was trying to compile the linux-ia64 kernel to use with the ski simulator and got an error message that the version of gcc-ia64-000216 (?)  was too old.

Regards
Progress

That message is wrong for IA-64.  It is removed by the IA-64 Linux
patch.  Did you apply that patch on top of the offical kernel sources?
If not, you need to do so.  It can be found at:

	ftp.kernel.org/pub/linux/kernel/ports/ia64/

I used to maintain a copy of gcc sources on ftp.cygnus.com, but that machine
has been down for 2 weeks now, and I haven't gotten any answer as to when it
will be back up.  That version of gcc was getting pretty old though, and
wasn't being actively maintained anymore.

If you have any recent OS distribution from any Linux vendor, then you can
get a good copy of gcc from there.  They all have source RPMS of gcc, which are
all pretty much the same compiler that I was maintaining on ftp.cygnus.com.
For instance, on ftp.redhat.com, or any mirror, you can find this in
/pub/redhat/beta/fisher/en/SRPMS/ia64/SRPMS/gnupro-1117-6.src.rpm

If you want a completely up-to-date copy of gcc, then you have to get it
from the FSF.
For gcc: <http://gcc.gnu.org>
For binutils (as/ld/etc): <http://sources.redhat.com/binutils>
However, these are development versions, and if you use them, you
need to be prepared to deal with occasional instabilities.  Also, there
are some known bugs that need to be fixed before these will be widely used.
E.g. there are kernel miscompilation problems to fix.

Since you are trying to build a kernel for ski simulator, I assume you
are looking for a cross-compiler for x86 host. You can find it at
<ftp://puffin.external.hp.com/pub/ia64/gcc-2.96-ia64-000717-snap001117-build3.tar.gz>.
Untar it from root directory and it will untar under opt/ia64.

Oops, it appears that the old assembler didn't support this
instruction.  I didn't realize that because I didn't start using it
until recently.

An easy workaround would be the following. In
arch/ia64/kernel/entry.h, change the first line of:

	#if defined(CONFIG_ITANIUM_ASTEP_SPECIFIC) || defined(CONFIG_ITANIUM_B1_SPECIFIC)
	# define MOVBR(type,br,gr,lbl)	mov br=gr

to

	#if 1
	# define MOVBR(type,br,gr,lbl)	mov br=gr

I think that should get you around the assembler problem.
Alternatively, you could upgrade the toolchain using the tar ball that
Khalid pointed you to.
