> rustc is notorious for throwing huge gobs of unoptimized LLVM IR at LLVM and expecting LLVM to optimize it all away. It might be a good idea to implement a cheap/fast optimization phase according to rustc assumptions, specifically for rustc, to clean up the mess. Keeping the rustc emit layer concise and clear should really be a goal, in my opinion. Obvious code is easier to audit.
