Unit tests: Under tests/, there are many small functions that create a tiny VM instance, map a few lines of assembly to its memory, run it and check the register state against the expected outcome. I’m also particularly interested in finding a nice way to either generate codegen code or at least test cases with the SAIL specification of the Arm ISA, hopefully when I have time.
