To run the regression suite, do:
./scripts/regress.sh
cargo test
cargo test doesn't test much, so most of the testing is done by regress.sh.
Note that these regressions need to find nasm on your path in order to
assemble the binaries to decode and simulate. I use a version of nasm provided
by the BYU ECEn 425 class 8086 toolchain repo.
To make sure that the regressions are run before each Git commit, run
scripts/install-pre-commit.sh for each instance of this repo that you clone.
