Hi Etienne. Have a good day
So far, I found some instructions that your cycle count module can't analyze. I don't know why.
Please check and give me some explanations:
vbic.i16 d0, #1 ; 0x0001
vbic.i32 q2, #1 ; 0x00000001
vmov.i16 q0, #1 ; 0x0001
vmov.i16 d0, #1 ; 0x0001
vmvn.i16 q1, #1 ; 0x0001
vmvn.i16 d1, #1 ; 0x0001
vorr.i16 q0, #1 ; 0x0001
vorr.i16 d0, #1 ; 0x0001
