Automatically synthesize a compiler

It's very time consuming and difficult to write compilers, especially for exotic specialized hardware. Diospyros showed that you could use e-graphs (egg) to build a very competitive rewrite based compiler for an architecture with explicit vector lanes. The performance and quality of the compiler depends a lot on the particular rewrite rules used. Finding these rules is a tedious, error-prone process. Ruler presented a technique to automatically generate rewrite rules from an interpreter that gives a DSL semantics. Their technique works well for generating rewrite rules for optimization, but it does not scale to generating rules for compiling. I'm exploring ways of combining these two techniques so that we can automatically generate efficient (but slow) compilers.
