If you need to modify the resulting EA, then you also need to make a copy for 0.
Hey, didn't properly get what you meant here.
Did you mean : Since I'm using a tcg_constant for 0, if the EA is to be modified later,
this constant would be an issue, in which case, I should make a copy for it ??
Yes.
Considering that, there are no tcg level modifications with this EA.
Ok, good.
However, the
underlying helper method, which considers this EA as a target_ulong type does modify it,
which I don't think should be an issue.
Correct, that's fine.
