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

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

ARM64:
C++: 
MOV             W0, #0x63

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 :/

BX LR?
 
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.
