|

- As a prereq, we need roc building on Windows (I'm not sure it does currently).
|
||||
- Definitely a solid bit different than elf, but hopefully after refactoring for Macho, won't be that crazy to add.
|
||||
- Look at enabling completely in memory linking that could be used with `roc run` and/or `roc repl`
|
||||
- Look more into roc hosts and keeping certain functions. Currently I just disabled linker garbage collection.
|

- Look more into rust hosts and keeping certain functions. Currently I just disabled linker garbage collection.
|
||||
This works but adds 1.2MB (40%) to even a tiny app. It may be a size issue for large rust hosts.
|
||||
Roc, for reference, adds 13MB (20%) when linked without garbage collection.
|
||||
- Add a feature to the compiler to make this linker optional.
