So I guess the question is how should we make sure the stack and heap are sized correctly. Using malloc to allocate the memory for lzma makes sense, but it is used in CAR too, so that complicates our decision.
lzma decompressor gets a void * from the caller. Caller, if CAR, uses on-stack pointer. RAM code can, if desired, use malloc'ed memory?
We never call lzma while in CAR. Now that would be kind of silly, would it?
Well, originally ulmza() was designed to be runnable in CAR on the OLPC.
What for? Decompressing to cache? This sounds a bit odd, with a 16kB scratchpad, and only 128KB cache.
