Constructor Optimization

[Benjamin Meyer]

Well a little bit more playing around and I have confirmed that gcc will =
not=20
optimize:
obj a =3D b + c + d...=20
to
obj a(b);
a +=3D c;
a +=3D d;
=2E...

The first one being the slower operation due to a New and copy at every s=
tep.

Combining "PRE_"  rand() and "_POST": (used rand() simply to make sure th=
at=20
the compiler wouldn't optimize away everything and give real world result=
s)

+Operator test (1 line of code).
        Normal Constructor, 1804289383
        Normal Constructor, PRE_1804289383
        operator+Copy, PRE_1804289383
        Copy Constructor, PRE_1804289383
        Normal Constructor, PRE_1804289383_POST
        operator+Copy, PRE_1804289383_POST
        Copy Constructor, PRE_1804289383_POST

Optimal +Operator. (multiple lines using overloaded +=3D)
        Copy Constructor, PRE_
        Normal Constructor, 846930886
        operator+=3DCopy, PRE_846930886
        operator+=3DCopy, PRE_846930886_POST
