| From | Jere <jhb.chat@gmail.com> |
I was thinking more along the lines of adding a classwide operation on the
root storage pool type. That shouldn't change anyone's implementation
ideally. Something like:
-- Parameter is mode "in out" to allow for it to clear itself if the implementation
-- so desires
function Is_First_Allocation(Self : in out Root_Storage_Pool'Class) return Boolean;
Added to System.Storage_Pools. Allow the implementation to implement it
however they like under the hood. They could, for example, add a boolean
to the private part of the root storage pool and add a child function/package that
sets it when the compiler implementation calls for the first allocation. It can be
implemented with a count. I'm sure there are a plethora of ways.
Since the operation is classwide and it is optional, it wouldn't affect anyone's
existing storage pools. it would basically just be there to give custom
storage pool designers a hook to know when it is portably safe to add
a custom header, regardless of the number of allocations an implementation
chooses to do.
It does place the burden on the compiler implementors to call it for the first
allocation, but I can't imagine that is a huge burden with today's IDE tools?
