micro-ochre

Copperbox revision 2736.

micro-ochre a genuine EDSL compiler - it optimizes! - that works!

micro-ochre generates Csound instruments. Just two opcodes - oscil and out - are supported, but the compiler uses a "proper" intermediate representation (K Normal Form) and it does genuine optimizations (const folding, beta-reduction, useless let elimination). The final codegen is flaky but it generates the test instrument and that instrument works.

Depending how you count I first started working on this 10 years ago (generating RTCmix with PLT Scheme), so although the success comes with heavy caveats, I'm pleased.
