From c0b0f32b4ec4db6961e1fc1f5ccd263598aa6df6 Mon Sep 17 00:00:00 2001 From: Cassie Jones Date: Sun, 1 Mar 2020 03:10:11 +0100 Subject: [PATCH] Add a compiler CLI The compiler CLI lets you output assembly, the pretty-printed code, or a compiled binary. It shells out to clang for assembling. You have to have clang installed, and you have to have the runtime library in the correct place. I need to figure out a way to embed the runtime library or something... --- Cargo.lock | 299 +++++++++++++++++++++++++++++++++++++++++++++++ Cargo.toml | 2 + src/main.rs | 91 +++++++++++++--
