| Unwind error handler library | |
| ---------------------------- | |
| This library provides an error handler that unwinds using the APIs in [`unwind.h`](../../include/unwind.h). | |
| This error handler can work even in cases of stack overflow. | |
| Note: Unlike most libraries, this is *not* built as a shared library. | |
| Error handlers must be part of the compartment that invokes them. | |
| As a result, this must be added as a dependency of each compartment that wishes to use it, rather than as a dependency of the firmware target. |
