[parisc-linux] 64-bit compiler millicode update

[Paul Bame]

This affects people building 64-bit kernels after willy's (not yet
available) changes, whereupon the $$mulI millicode routine becomes
needed.

New cross compilers will soon be available, but if you just want to
get the millicode change and no others, replace your 64-bit libgcc.a
with [ftp|http]://puffin.external.hp.com/pub/parisc/binaries/libgcc.a.gz

The full xc with this change and also the recent glibc changes is now 
available at,

[parisc-linux] C100 Self-Hosting

[Greg Ingram]

I tried to self-host on my C100 with the recent root filesystem from
ISIEE.  The first problem was I needed the CVS bins.  I grabbed the
sources from Debian and the build went without a hitch.  I've posted a
tarball of (I hope) all of the relevant bits here:

	http://www.symsys.com/~ingram/linux/parisc/cvs.tar.gz

I checked out the linux and palo sources, configured the kernel and made
dependancies.  I ran into the following problems with 'make palo':

1)  arch/parisc/Makefile specifies the cross-compiler

I guess most people are using the cross-compiler so maybe it should stay
that way for now.  Anyway, once I commented out that line the kernel build
took off.

2)  conflicting types for mem{cmp|cpy|set} built-ins 

Lots and lots of warnings.  Should I add -fno-builtin?

3)  conflicting types for off_t in <stdio.h> and "linux/types.h"

I was able to dodge this error by defining '__off_t_defined' right before
including <stdio.h> in palo/lib/elf32.c.

And now [ drumroll ] the build succeeds and the self-built kernel boots.  

Woohoo!

No.  I haven't heard any complaints about my proposed change to fix the
warnings, so I'm going to commit it.

There's something wrong with the compiler:

/opt/palinux/lib/gcc-lib/hppa-linux/2.97/tradcpp0: /lib/libc.so.6:
	version `GLIBC_2.2' not found (required by
	/opt/palinux/lib/gcc-lib/hppa-linux/2.97/tradcpp0)

we're trying to track it down.  in the meantime, use your current toolchain
and the libgcc.a from /opt/palinux/lib/gcc-lib/hppa64-linux/2.97/

OK, the problem was that I built the xc on a system running Debian unstable 
which has glibc 2.2.2. So the xc didn't work on systems with an older glibc. 
I'd always gotten away with it up until now. So from now on I will build all 
xc's on a system no newer than the Debian stable release (currently potato, 
glibc 2.1.3).

I have placed a new xc at,

ftp://puffin.external.hp.com/pub/parisc/binaries/LinuxX86/xc-20010305.tar.gz

This xc includes Alan Modra's recent merge to upstream 20010204.
