## Limited support
|
||
|
|
|
||
|
|
The following devices can run Wasm3, however they cannot afford to allocate even a single Linear Memory page (64KB).
|
||
|
|
This means `memoryLimit` should be set to the actual amount of RAM available, and that in turn usually breaks the allocator of the hosted Wasm application (which still assumes the page is 64KB and performs OOB access).

### Legend:
|
||
|
|
⚠️ This architecture/compiler currently fails to perform TCO (Tail Call Optimization/Elimination), which leads to sub-optimal interpreter behaviour (intense native stack usage, lower performance).
|
||
|
|
There are plans to improve this in future 🦄.
