Tutorial Returning Int64/long in ARMv7/ARM64

[AndnixSH]

As requested by some modders.
I used Unity to compile my own il2cpp game just to check the lib lol

C#:

return 99l;

ARMv7:

MOV             R0, #0x63 ; 'c'
MOV             R1, #0
BX              LR

63 00 A0 E3  00 10 A0 E3  1E FF 2F E1

ARM64:

MOV             W0, #0x63
RET

60 0C 80 52  C0 03 5F D6

---------------------------------------------------------------------------------------------------------------



C#:

return 999999l;

ARMv7:

MOV             R0, #0x423F
MOV             R1, #0
MOVT            R0, #0xF
BX              LR

3F 02 04 E3  00 10 A0 E3  0F 00 40 E3  1E FF 2F E1

ARM64:

MOV             W0, #0x423F
MOVK            W0, #0xF,LSL#16
RET

E0 47 88 52  E0 01 A0 72  C0 03 5F D6

return? mean like keep value or just add value? or what?

Keep value

 

[GreatBigPanda]

what about just a return, like if I have a method that is damage I just want to put a return on it so it does nothing but in ARMv7 I cant find it anything that can give me a ARMv7 return cause the online hex converter can convert it :/

 

[PadaHama]

can you help me return #1 (long) in arm

BX LR?

@AndnixSH if i use 7f 04 a0 e3 1e ff 2f e1 in arm7 ,it's really work?

Try it and let me know if it works or not

yes it should

I already got it a while back but thanks for replying

Need to know how to do int16 or a short variable.
This is good info if I ever need to work with a long variable.

If you can do this for short I'll be in your debt haha. Seriously though I'm failing miserably and can't compile code to check it myself or I would. I'm just a c# guy.

Thanks for this

What about a particular string ?

 

[HazkeLs]

Does anyone have some code for x64 that returns a large value in String and another to return an Int ?, Thanks in advance!
