[Sdcc-user] Bank switching (Z80, Amstrad CPC)

[Duncan B. <dhg...@fa...>]

Hi Folks,

I'm hoping to use SDCC to implement a (very!) simple Lisp on an Amstrad
CPC.  Now that Maarten has kindly explained the 1kB heap size I can
proceed, but I have a related question: can SDCC make use of switched
RAM offered by the system?

Specifically, the Amstrad is capable of switching out 16kB banks of RAM
so that the Z80 - normally limited to a 64kB address space can have up
to, IIRC, around 512kB RAM.  Details here:

Faced with writing my own memory management code to allocate and free
cons cells, I thought I'd ask whether SDCC is capable of managing
bank-switched memory, so that I can just malloc() away to my heart's
content?  

If not, and I go ahead and implement something, would this functionality
fit in SDCC?  I'm suspicious that it wouldn't, as it's specific to just
one type of Z80 system.
