Hi Tamar,
Using -falign-loops=5 indeed brings back the performance.
The adrp instruction has same address (0x4ae784) by setting -falign-loops=5
(which reduces misalignment to 4) with/without a2f4be3dae0. So I guess this is
really code-alignment issue ?

(Also in our latest builds the regression has seemingly gone away without any
adjustments to code alignment)

Thanks,
Prathamesh
