Thanks.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106671 was closed as
invalid pointing to the same commit in llvm. What's going on here?
Where's the corresponding feature request for GCC?

TBH I'd missed that that got closed, basically it's what's in the report
there - the GCC people really dislike the idea of adding landing pads
and want to see veneers added by the linker to fix up issues where
they're missing.

At the least, I could imagine there being a `-fno-omit-bti-pads` or
whatever for the kernel to opt into this behavior.

That would be useful.
