Playdate memory allocator about playdate-nim HOT 6 CLOSED

Ok, yes seems like compiling for the simulator just uses the std functions no matter what.
Maybe we should also try reverting back to switch("os", "any") compiling for the simulator too.
I remember removing this setting time ago.

I started playing around with using the playdate realloc method for everything in Nim: Nycto@memory

I've got things working on the simulator, but everything immediately crashes when trying to use it on device. Feel free to poke at this and see if it makes sense.

I thought the _malloc_r, _realloc_r and _free_r definitions in setup.c (SDK folder) were enough to override the default malloc strategy, but I'm not sure if this is really the case.

What makes you think Nim wasn't using the SDK provided functions?

This might just be a simulator thing, actually. When I completely comment out all the memory allocation functions in setup.c, I'm still able to compile and run the simulator. But I just tried compiling for the device and it looks like it's failing appropriately

I have to admit to being a bit stumped so far. I’ve tried various compiler and linker flags, but nothing seems to impact the simulator. If you get a chance to look at this, I would love a second set of eyes.

Since I was stuck, I switched back to working on this branch: https://github.com/Nycto/playdate-nim/tree/memory

I got it mostly working, though I still have one workflow failure to investigate. I think this might be the right path forward as it’s the official Nim way to override malloc.

I’m going to do some testing this morning to see if it resolves my memory corruption issues
