[avr-gcc-list] an idea: adding serial sram to avr to extend heap storage

[Raymond Moore]

I am working on several projects that require more sram than most AVRs
have.  I don't particularly need more processing power but it would be
nice to have much larger variable storage space.  I can work with a
serial sram and use it for external storage already but it would be
nice to have an option to be able to turn that serial sram into heap
storage.

Due to the complexity of gcc I am assuming this will be a non-trivial
task but it is something I would be willing to work on.  My question
is, where in the gcc source would I look to start redirecting heap
storage?  Yes, I'm lazy, and I just had this idea about 10 minutes ago
and haven't started digging into the source yet.


Thanks,
