So the GC is kind of out.
Yeah, I'm wondering if that's just a basic truth for embedded.
Can D implement a ref-counting GC? That would probably still be
okay, since
collection is immediate.
This is technically possible, but you said you make few
allocations. So with the tax on pointer write or the reference
counting, you'll pay a lot to collect very few garbages. I'm not
sure the tradeoff is worthwhile.
Paradoxically, when you create few garbage, GC are really goos as
they don't need to trigger often. But if you need to add a tax on
each reference write/copy, you'll probably pay more tax than you
get out of it.
Modern consoles and portables have plenty of memory; can use a
GC, but
simpler/embedded platforms probably just can't. An alternative
solution
still needs to be offered for that sort of hardware.
