A maintainable and more precise version of what was a hacky but useful script, exploring the compilers YUL lowering unit. It analyzes a given shared objects from the debug dump and outputs: - The count of each YUL statement translated. - A per YUL statement break-down of bytecode size contributed per. - Estimated `yul-phaser` cost parameters.

The `revive-explorer` is a helper utility for exploring the compilers YUL lowering unit.
|
|
|
|
It analyzes a given shared objects from the debug dump and outputs:
|
|
- The count of each YUL statement translated.
|
|
- A per YUL statement break-down of bytecode size contributed per.
|
|
- Estimated `yul-phaser` cost parameters.
|
|
|
