Trees were refactored, and we currently have:
struct tree_base
{
ENUM_BITFIELD(tree_code) code : 16;
/* 48 bits for various bitfield flags */
union tree_ann_d *ann;
} /* So on a 64-bit host this is 128bits = 1

Can you measure how much memory do all the overload nodes take in the big
testcases? Theoretically, an OVERLOAD could measure 8 bytes or so (on 32 bit
systems). So we currently waste more than 100 bytes per

If you look at both PR 8361 and 12850, they average both more than 40
Overloadeds. Those are both
real code so I don't know why people think this is stupid. Also linked lists

I would imagine that in real world, there are either a rather small number
of overloads of a name (less than five) or very many (more than 20 or 30).
Most code I've seen don't use many overloads (falling into

Though fixing that still gives the same number.

8361 also have simular interesting results:
average OVL length: 44.709989
But I think my counting is wrong as we can have DECL in the chain.

I added some stats to when chaining to the ovl and got the following
interesting result for PR 12850:
average OVL length: 57.498998
So we have an average length of 57 which is long and shows that we are ta
