Hi, Got a small bugfix here regarding BTIs and trampolines.
If two functions require trampolines, and the first has BTI enabled while the
second doesn't, the generated template will be lacking a BTI instruction.
This patch fixes this by always adding a BTI instruction, which is safe as BTI
instructions are ignored on unsupported architecture versions.
I don't have write access, so could someone commit for me?
Bootstrapped and tested on aarch64 with no regressions.
