thanks, mirek.
i think i was misleading in my post..
1) was, how intensively does the grahics computation rely on float/double computation? would it be easy to rework the containing parts to fixpoint, like many other GUI libs have it?
2) the goal fot the UPP HEAP is, to allocate *once* a huge chunk, say 64 MB, in the upp application, and after its done, it releases the complete chunk, thus the memory does get fragmentated only *inside* the upp application..
3) do you know of an easy way of emulating a TLS variable? in UPPHEAP we need it also, for the
thread__ Heap heap = {
{ DI, DI, DI, DI, DI, DI, DI, DI, DI, DI, DI, DI, DI, DI, DI, DI, DI, DI }
};
in sheap.cp (what is it for btw. ?)
in Random and Mt.cpp we could circumvent the use of thread__, but here...i doubt. so why do you need TLS here..
