While discussing if is worth using const parameters for string and
double types in a Lazarus bug report (
http://bugs.freepascal.org/view.php?id=12642 ), it was noticed that
does not make difference using constant parameters or not for double
types.
So is this the expected behavior or a bug in fpc?
It is the expected behaviour.
Thanks.
Maybe the documentation
(http://www.freepascal.org/docs-html/ref/refsu50.html#x126-13300011.4.4)
can be modified to clarify this since the statement:
"A constant argument is passed by reference if its size is larger than a
pointer."
leads to the conclusion that double types (8 bytes) would be passed as
reference in 32bit code.
Well, the bigger problem is that this is target dependent.
