Hi, The use of RET vs BR also has microarchitectural side effects. AFAIU, RET should always be paired with an earlier BL/BLR to avoid interfering with branch prediction.
So depending on the circumstances, either one of these should be addressed: * Clarify that this is actually a function return , and RET should be used anyway, regardless of BTI. * Keep BR and add BTI J landing pads where appropriate, if this wasn't really a function return.
