...I'm sorry, what? Fatal errors are normal for you people? Seriously? 
I've been compiling my own kernel since 2004, I've never seen one. I'd 
like some explanation on this.

If you already know it's broken, there's no point testing it. Why are 
you so desperately trying to ignore it? Are you getting paid to be here 
or are you this stupid for free?

Have you tried calling an ambulance on Android lately? I can reboot my 
Huawei with schedtool on Termux. Unrooted, stock. THE LINUX KERNEL IS 
MEASURED IN HUMAN LIVES.

How many times do you need to ignore an obvious compiler bug until you 
hope it away?

llvm+clang compiles with cmake. In "Release" mode, cmake helpfully 
appends a -O3 for you, which is the kind of "optimization" where the 
compiler deliberately misinterprets the programmer's intention to 
declare an UB, and then uses its godlike might to decide the target of 
an explicit constcast is unreachable. If you recompile systemd with the 
result, it will not understand your password anymore. This was 
yesterday. The day before, it errored out on m4 with some undefined 
linkage into compiler-rt. WITH AN EXPLICIT --rtlib=libgcc FLAG ON A 
GCC-BASED DISTRO

#!/bin/sh
exec /usr/bin/gcc "${@}" -O2

...or did you find a third broken compiler somewhere?

Why not? You seem to be doing just fine.

Ask OpenBSD for a toolchain, see if it works. Or better yet, ask them to 
build the kernel for you.

This has already been Reviewed-by.

I'm rejecting both these morons as invalid. Please review everything 
they've been doing lately.

Yo, Linus! What the fuck is this shit?  I'm tempted to I don't care 
which one of these whiny little bitches cut your dick off and stuffed it 
into your mouth. Either spit it out or swallow and shit it out, but we 
can't afford this.

Source-based Linux is dead. Gentoo is a cronjob spewing out endless 
broken stage3's, and every single Exherbo dev has unsubscribed from 
their own mailing list. I'm the last one standing. I've spent the last 
two weeks trying to review the damage. I'm not going to package it 
either, but you need to know why. Also, I've quit my job because I 
couldn't sleep for four days straight.

I'm typing this in Thunderbird because fucking KONSOLE SEGFAULTED WHEN I 
TYPED VIM. I do not feel at home on a binary distro, and I cannot build 
a browser on a real one. I would like to explain politely, under the 
[foxfire] tag. Anyone who does not want to know why I think it likely 
that some Gentoo+ maintainers have literally committed suicide, feel 
free to filter it out.

Should you happen to agree with some of my opinions, I'd like you to 
revert every single "fix" for "undefined behavior" that was merged for 
clang. The C standard committee does not define the result because they 
have no idea whether it makes sense in context AND THEY KNOW IT. I mean 
seriously, why do these need a lawyer to know whether or not const is 
just a helpful suggestion in a UNIX KERNEL?

And we build with -std=gnu -fgnu-keywords -fuck-your-pdf (I mean, did 
you get at least this far?). We don't have any more flags to tell you 
you're not in Kansas, Dorothy. You don't give us more.

There's nothing undefined about the concept of "Linux boots on MIPS". 
THERE IS LITERALLY NO OTHER DEFINITION OF A KERNEL AND IT WORKS WHEN I 
BUILD THE TOOLCHAIN. If you fucked it up, that's not our problem.

cmake+llvm builds with -Wno-maybe-uninitialized. They can't even fix 
their warnings, so they hide it. This is not a compiler, it's a random 
number generator.

I came here as a last, desperate stance to get organized and shovel the 
shit back in the horse, and this is what I find. Oh well. At least it 
will be educational.
