I want to hack 64bit portion

There is no information in this regard or tutorial

For example, in 32bit portion

 mov r0, r7 -> 381C

 nop -> C046

 bx lr ---> 7047

 In 64bit instruction and corresponding to the hexadecimal

 mov r0, r7 -> 64bit instruction -> hex

 nop -> 64bit instruction -> hex

 bx lr -> 64bit instruction -> hex

 

Please guide me or give suggestions, thank you

I think MOV R0, R7 in ARM64 is MOV W0, W19 or MOV W0, W20

 

And for NOP AND RET (RET is BX LR in ARM64), use the converter: http://armconverter.com
