Depends on how the compiler feels at the moment :) -- it might keep
it in the register it comes in (for it actually is the first
argument, $r3).
At least, for today, whilst we still run on a decent architecture...
for example the code:
-(id) init {
self = [self initSpecial];
return self;
}
should alter everything in exactly the same way as:
-(id) init {
return [self initSpecial];
}
Exactly. Note also that the former is *needed* in case of more
complex initialization:
-init {
self=[self initSpecial]; // also may need to check for nil
depending on the following code
[self whatever];
return self;
}
