### Optimizer
*Warning:* The optimizer is still under development.
*Note:* The optimizer is still under development.
Currently supported optimizations:
* Strip debug info
* Set spec constant default value
* Freeze spec constant
* Fold `OpSpecConstantOp` and `OpSpecConstantComposite`
* Unify constants
* Eliminate dead constant
* Inline all function calls in entry points
* General
* Strip debug info
* Specialization Constants
* Set spec constant default value
* Freeze spec constant
* Fold `OpSpecConstantOp` and `OpSpecConstantComposite`
* Unify constants
* Eliminate dead constant
* Code Reduction (Entry Point Functions)
* Inline all function calls exhaustively
* Convert local access chains to inserts/extracts
* Eliminate local load/store in single block
* Eliminate local load/store with single store
* Eliminate local load/store with multiple stores
* Eliminate local extract from insert
* Eliminate dead instructions (aggressive)
* Eliminate dead branches
* Merge single successor / single predecessor block pairs
* Eliminate common uniform loads
