Add unit tests

[dguido]

[joshwatson]

Do we have a standard unit test framework that we use?

[montyly]

I dont think so

@Mossberg was working on a fork of solc that could output the edges of a smart contract
We could build unit tests on top of it

Yup, the solc fork is here: https://github.com/trailofbits/solidity/tree/basic-block-edges

and some example current output:

[I] mark forge ~/c/e/s/corpus ❯ mysolc qq.sol --bin-runtime

0x57 -> [0x6e]
0x85 -> [0x86, 0x94]
0x93 -> [0x7d]
0x9b -> [0x58]
