Subject: [EXTERNAL] Re: [PATCH v2 00/28] Add support for Clang LTO
Hey Ian,
It was nice to meet you at Linux plumbers. You might want to take a look at
this series. It implements builds of the Linux kernel with LTO. It would be
good to get eyes on it and help review it from f

Hey Ian,
It was nice to meet you at Linux plumbers. You might want to take a
look at this series. It implements builds of the Linux kernel with
LTO. It would be good to get eyes on it and help review it from folks
working on this from the GCC angle. The series has some configs that
split where

You are right Peter, my apologies.

Please don't nest series!

FWIW, this gives me a happy booting x86 kernel:
# cat /proc/version
Linux version 5.9.0-rc3+
This patch series adds support for building x86_64 and arm64 kernels
with Clang's Link Time Optimization (LTO).
In addition to performance, the primary motivation for LTO is
to allow Clang's Control-Flow Integrity (CFI) to be used in the
kernel. Google has shipped millions of Pixel devices
