I forget; is the target of EX treated as a data access or as an

The 256-byte cache line containing the target instruction is loaded into
I-cache.
So, this would seem to point towards putting the target near the
instruction, if you can, or at least no more than 244 bytes away (worst
case, maybe a bit less), or possibly grouping frequently executed
targets together using Martin T's. favorite LOCTR assembler instruction
and hoping that the line stays in cache.
Thoughts?
