Compiler backends:

– Quick

– Optimizing

– Portable

 

 

Quick Backend

- Medium level IR (DEX bytecode)

- Low level IR

- Native code

- Some optimizations at each stage

 

Portable backend

- Uses LLVM bitcode as its LIR

- Op)miza)ons using LLVM op)mizer

- Code genera)on is done by LLVM backend

 

Portable backend는 5 이후 제거됨. 6부터는 오직 Quick, Optimizing만 사용 가능
