Hi Matthias,

again you helped me a lot.

I recalled that I had success in the early days of llvmlinux with...

CONFIG_PARAVIRT=n

...as suggested by Steve Rostedt.

This needed some more hackish kconfig kungfu these days - patches attached.

In the end I could boot into a 4.14.37-1-iniza-llvmlinux kernel
(kernel-config and dmesg-log attached).

Concerning your analysis...

Is this a clang-bug?
Or can this be solved in the linux-kernel code?
What are your suggestion?
And can you help on getting this fixed with the help of your Chromium
team and/or bring it to the right persons?

IMHO an analysis like you did might help, too.
I am not an expert in this area to say it is good/correct but I could
follow and read it like a thriller.
Where is Lieutenant Columbo when you need him :-)?

Moreover, a test-case can be helpful, e.g. "Is clang clobbering RCX?"
when it's a clang-bug.

I tried to find some suitable test-case myself.

The clang-source has a test-dir, but this is new to me.

I tried to run a single test like test/Sema/asm.c in [1] with
llvm-tools Debian-package which ships "lit.py" script.

Not sure if this is a suitable for x86-64 (amd64) as the first line says...

// RUN: %clang_cc1 %s -Wno-private-extern -triple i386-pc-linux-gnu
-verify -fsyntax-only

root# cd /path/to/clang-source

root# python /usr/lib/llvm-7/build/utils/lit/lit.py -sv test/Sema
lit.py: /usr/lib/llvm-7/build/utils/lit/lit/TestingConfig.py:101:
fatal: unable to parse config file
'/path/to/clang-source/test/lit.cfg.py', traceback: Traceback (most
recent call last):
File "/usr/lib/llvm-7/build/utils/lit/lit/TestingConfig.py", line

config.test_format = lit.formats.ShTest(not llvm_config.use_lit_shell)
AttributeError: 'NoneType' object has no attribute 'use_lit_shell'

Not sure if you have any experiences in this area, but I think asking
on llvm-dev is a good idea.

If we have a reproducible test-case we could ask on llvm-dev?

In the case of linux-kernel...
Ask Linux/x86 folks for a test-case to see if the compiler clobbers RCX?
Show your analysis to Linux/(x86)/KVM folks?

Some ideas.

I believe you, really.
Can you give me your kernel-config?
What is the setting of CONFIG_PARAVIRT?

Thank you.
