As of 2022-04-02, the p4c compiler passes all but 64 of its included
tests.
The relatively small group of tests whose names begin with 'ebpf' and
'ubpf' fail. They work fine in the continuous integration tests on
the https://github.com/p4lang/p4c project, because the VM used to run
those tests has additional software installed to enable it. Perhaps
future versions of this VM will enable the ebpf and ubpf back ends to
pass these tests, also. Contributions are welcome to the needed
changes in the VM build scripts to enable this.
As of 2023-07-01, the p4c compiler passes all of its included tests,
except for some of the p4testgen tests (if those are enabled).
