From 8e13b1303a0d152c2f3b68f2421163e94fdf226c Mon Sep 17 00:00:00 2001 From: Griffin Smith Date: Sun, 28 Mar 2021 13:28:49 -0400 Subject: feat(achilles): Implement a Unit type Add support for a zero-sized Unit type. This requires some special at the codegen level because LLVM (unsurprisingly) only allows Void types in function return position - to make that a little easier to handle there's a new pass that strips any unit-only expressions and pulls unit-only function arguments up to new `let` bindings, so we never have to actually pass around unit values.
