I just tried that and there is still no output. I have
append="rd.lvm.lv=maroon/usr console=uart,mmio,0xf8050000"
in elilo.conf (and confirmed that it got installed that way in
\EFI\gentoo\elilo.conf). In a test with 3.12.7-gentoo compiled with
gcc-4.5.4, I could see the commandline being seen this way by the
kernel. The same version, cleaned, rebuilt with gcc-4.7.3, does not
output anything at all and reboots after a few seconds.

Bother.
Perhaps you could try to find which code is the problem by doing
a mix-n-match building some parts of the kernel with gcc-4.5.4
and some with gcc-4.7.3. I'd start off with using the old compiler
for arch/ia64/kernel/* (perhaps arch/ia64/mm/* too) and the new
compiler for everything else. If that works, then "bisect" by adding
more files to the 4.7.3 list.
This assumes the problem is localized in a ".c" file. If the issue
is with some static inline function from a .h file - well, things will
be much harder :-(

Thanks for your suggestion. How do I do that properly?
I think the following will not work, because changing CC will cause
arch/ia64/kernel to be rebuild, right?
# make -C arch/ia64/kernel CC=gcc-4.7.3
# make CC=gcc-4.5.4
And what would you suggest to add after ia64/kernel and ia64/mm? I do
not know much about the parts of the kernel that run at this early
stage.

yes - you'd have to fake Kbuild/make into thinking you were using the same compiler
all the time. I don't know if there is a "proper" way to do that. I'd do it by writing
a shell script "mycc" that in pseudo-code looks like:
---------
#!/bin/bash
USECC=gcc-4.7.3
# Look to see if we have a ".c" file argument on a special list
for i
do case "$i" in
*.c)
if grep -s "^$i$" ~/special
then
USECC=gcc4.5.4
fi
;;
esac
done
$USECC "$@"
----------
Then start with:
$ find arch/ia64/kernel arch/ia64/mm -name "*.c" > ~/special
$ make CC=mycc

Not a clue. If My guess that the problem is in those arch specific files, then
you have a list of ~64 to play with ... bisection would get you to one (if just
one is the root of the problem) in six builds.
If I'm wrong ... well the full list of files built in a typical configuration
is a couple of thousand. So eleven builds.
If the problem is in a static inline" - well none of this will help :-(

H.J.
Would the approach below help debug an issue with why ia64 kernel is completely[*]
broken with gcc-4.7.3, but works with gcc-4.5.4?
If not - do you have a better suggestion on how to narrow the scope of the
problem.

Hi,
Did you compile kernel with -O2 or -O1 optimization?
For some time now, ia64 kernels behave strangely and this might be due
to gcc optimization. Have a look at [1] (long). As a quick summary,
you can jump directly to comment #106 [2].
Although reported on Debian BTS, I've performed tests on Gentoo and
found similar problems (also reported in [1]).
I don't know exactly when problems first appear, but I can generate
broken kernels with gcc 4.5 (tested on Gentoo). So, the problem is not
limited to gcc 4.7, as implied in comment #116 too [3].
And as I was stating in comment #106, given a working kernel
configuration, simply changing one setting from built-in to built as a
module can lead to a non-working kernel.
But what really surprised me the most is that I didn't found any clear
allusion to this issue on linux-ia64 list, except a quick comment I
made in a post, back in March 2012 , during kernel 2.6.38 development
cycle [4]!
All the questions I had in comment #106 [2] are still valid and remain
unanswered.
So, I would be interested if Intel/hp developers (Tony? Hongjiu?
Fenghua?) can add comments to clarify how ia64 kernel development
works and how is it possible that this issue isn't affecting every
ia64 users.

I build latest Linus and linux-next kernels to keep on top of Linux changes
that break ia64. But I do this on top of a distro-installed system and
use whatever default gcc version comes with it. Currently using gcc 4.3.4
which hasn't had any problems.

Thanks Tony, this clarifies a little bit. So at least we know that gcc
4.3.4 is fine... but old ;-)
May I ask you what do you mean by "distro-installed" system? Do you
have a custom distro at Intel? Is it base on or a fork of a known one?

Hello everyone!

Thanks for that hint!
-O1 boots with output (the default is -O2 and does not work, and -Os or
CONFIG_CC_OPTIMIZE_FOR_SIZE does not work either).
I get an oops, though:
[ 56.305585] Unable to handle kernel NULL pointer dereference (address
000000000000003c)
[ 56.305842] modprobe[896]: Oops 8821862825984 [1]
Logs attached. The same config worked with gcc-4.5.4.
I assume it is best to first make -O1 work and then progress to -O2 later?

Depends on whether you have a need to debug this on gcc4.6
It seems that newer gcc (4.8.2) works again (see the Mikael/Mikulas
thread on "ski" on this mailing list. I also managed to build a kernel
with gcc 4.8.2 and boot it on my rx2600.

Tony, is GDB working correctly with your gcc 4.8.2-compiled kernel?
Indeed, one noticeable evidence of optimization's breakage is GDB
stopping with SIGTRAP at address 0 as soon as GDB's run command is
executed [1].

Seems ok. Tested using "GNU gdb (GDB) SUSE (7.5.1-0.7.29) I took a
"Hello World" program. Set a breakpoint at "main". Started running.
It stopped at the breakpoint. "s" stepped a line and printed the
Hello World. "c" continued until child terminated.
Kernel is the latest linux next (tag = next-20140124).
