I just checked. Up until XE2 it's documented regarding evaluation order for
register and pascal calling convention (the others are undefined with
exception of passing order), for XE3 it's only passing order for the two
and from XE4 on it's even don't care for the passing order... :/
If you want I can provide you the link later on.
