Get a proper command line parser #4580

Closed widlarizer closed 1 week ago

widlarizer commented 2 months ago

Feature Description

Currently, we use a homemade getopt in kernel/driver.cc. We have lots of single letter options so to add a feature I want a full word option lke --option=value, which we don't support currently, which is probably why we have many single letter options in the first place.

Let's move to a boring, normal solution like cxxopts (C++11) or argparse (C++17). Our current demands will be met by just about anything, so we have to think about what we want from command line argument parsing in the future to pick something

This will have to respect https://github.com/YosysHQ/yosys/pull/3973 and other possible quirks
