## Dead path checker
|
|
|
|
Dead path checking is about removing paths in the pipeline that
|
|
lead to nothing. For instance, if there's no source or no sink
|
|
in a path. This pass is the only one that modifies the AST.
|
|
|
|
This is the third step of the pipeline:
|
|
```
|
|
+---------------------+ +---------------------+
|
|
| | | |
|
|
---> | AST & TypeTable | ---- deadpathck ---> | AST' & TypeTable' | --->
|
|
| | | |
|
|
+---------------------+ +---------------------+
|
|
```
|
|
|
|
### Current status:
|
|
|
|
* [x] Remove branches that are dead from the list of connections.
|
|
* [x] Remove the components from the collected list of components.
|
|
* [ ] Remove statements that are dead code:
|
|
- [ ] Do not instantiate components.
|
|
- [ ] Do not compute expressions for unused variables.
