NullChecks= 1

Enable or disable code generation for null checks.

Global null check support is enabled by default when il2cpp.exe is launched from the Unity editor.

Disabling this will prevent NullReferenceException exceptions from being thrown in generated code. In *most* cases, code that dereferences a null pointer will crash then. Sometimes the point where the crash happens is later than the location where the null reference check would have been emitted though.

ArrayBoundsChecks= 2

Enable or disable code generation for array bounds checks.

Global array bounds check support is enabled by default when il2cpp.exe is launched from the Unity editor.

Disabling this will prevent IndexOutOfRangeException exceptions from being thrown in generated code. This will allow reading and writing to memory outside of the bounds of an array without any runtime checks. Disable this check with extreme caution.

DivideByZeroChecks= 3

Enable or disable code generation for divide by zero checks.

Global divide by zero check support is disabled by default when il2cpp.exe is launched from the Unity editor.

Enabling this will cause DivideByZeroException exceptions to be thrown in generated code. Most code doesn't need to handle this exception, so it is probably safe to leave it disabled.
