joaomoreira added a comment. Regarding https://github.com/ClangBuiltLinux/linux/issues/1737:
Weirdly enough, I double-tested the behavior for -flto=thin + -mibt-seal; the kernel did boot fine on my setup, but when dumped/grep'ed for ENDBRs, it had ~500 less ENDBRs throughout the binary. Considering that LTO-based optimizations applied with -flto=thin should have also been applied with -flto (which means, things like dead-code elimination should be symmetrical in both generated binaries), and also given the confirmation that -flto=thin won't properly keep address-taken details across translation units, my understanding is that -mibt-seal must be disabled when -flto=thin. Thus, submitted the patch even though I was not able to reproduce the bad behavior.
