I thought it might be fun to attempt to tackle Eric Wastl's Advent of Code 2020 challenge using my bootstrap compiler, as well as being useful exercise for debugging the compiler. This compiler supports a subset of C, fairly similar to that described in the 1st edition of K&R.
As I start this challenge on 1 December, I don't know how complex the steps are likely to be, and whether a C-like language will prove a good choice. Nor do I know how much more work fixing bugs and implementing new functionality I'll have to put into my compiler to make, but it'll be interesting to see.
