Curious about all this branch trampoline talk. Do you have data to show
negative impact with things as-is?

Also, was powerpc/32 broken then without this? The commit log seems to
suggest so, but I don't think that's the case. How was this issue noticed?

Are there other future CPU families being planned where this is all true for
as well? Are they goin to be 32-bit as well?
