@nathanchance

Hope you will provide a pre-release of 19.1.0-rc1 as SLIM toolchain on kernel.org when it is released?

Yes, I plan to.

[nathanchance]

LLVM 19.1.0-rc1 released: https://github.com/llvm/llvm-project/releases/tag/llvmorg-19.1.0-rc1

I am building toolchains for kernel.org now.

[dileks]

@nathanchance
Thanks for uloading!

Can you move all prereleases (RCx) to a prereleases (plural) directory?

Only keep the latest stable SLIM toolchains in the root directory and move all previous stable releases to a archives directory, please?

Thanks.

[nathanchance]

I'd rather not complicate the maintenance of the folder structure for myself at this point but I'll consider cleaning up -rc builds once the stable ones are available.

[dileks]

It's up to you.

When you do a cleanup, please consider:

[ Documentation/process/changes.rst ]
 Clang/LLVM (optional)  13.0.1           clang --version

@nathanchance

Are there any extra patches for Linux v6.10-rc4+ required to build with LLVM 19.1.0-rc3?

[nathanchance]

I think https://git.kernel.org/linus/2bac084468847cfe5bbc7166082b2a208514bb1c might be the only one needed for 6.10. It is not needed for 6.11-rc1+, as it landed then.

[dileks]

@nathanchance
Thanks!
Typo: That should be Linux v6.11-rc4 not v6.10-rc4.

[dileks]

INFO: Yes, I was able to build Linux v6.11-rc4 and v6.11-rc5 with LLVM/Clang v19.1.0-rc3 successfully.

Tomorrow, Tuesday 03-Sep-2024 is the release-date of 19.1.0 FINAL, let's see.

[dileks]

LLVM 19.1.0-rc4 released:

https://github.com/llvm/llvm-project/releases/tag/llvmorg-19.1.0-rc4
https://discourse.llvm.org/t/llvm-19-1-0-rc4-released/81039

From @tobiashieta

I have decided to do another RC and release RC4 today, there are some important commits that we still wait for and the
number of changes are pretty huge.

For RC4->Final - I will be VERY conservative with the patches we accept. So please note this if you want to submit a patch.

Today 15-Oct-2024 we all expect LLVM version 19.1.2.

@nathanchance
Thanks for the quick uploads of previous SLIM LLVM-19 toolchains to kernel.org.

@nathanchance
I wanted to switch with the new SLIM toolchain to Linux version 6.12-rc3+.
You happen to know of missing patches from upstream for x86-64 arch?

You will need https://git.kernel.org/gregkh/char-misc/c/506a1ac4c4464a61e4336e135841067dbc040aaa if you build with -Werror. It should be in 6.12-rc4 now that it is in Greg's tree. Otherwise, I am not aware of any other necessary patches, that is the only one I am applying on top of 6.12-rc3.

@nathanchance

With one day delay we finally have LLVM version 19.1.3.
Can you build a new SLIM toolchain on kernel.org?
Thanks.

Upstream announcement:

LLVM 19.1.3 Relased!

As it concerns release 19.1.4

Potential ABI break in 19.1.3

[dileks]

LLVM 19.1.4 Release Update

Quote:

The schedule is that we should release 19.1.4 today. But unfortunately I haven’t had time to work on the release backlog and GitHub changed how rebasing works so I have to rework my script for merging fixes.

In order to not rush a release I am going to push 19.1.4 until next week so I have time to merge changes in a orderly fashion.

That means 19.1.4 will be released the 19th of November.

I am sorry for the delay.
