Compilers in Rust: Understanding Cranelift’s (ISLE) lowering rules (Part 2)

So, how does Cranelift, a Rust-based code generator, efficiently handle instruction selection and lowering? In this episode of Exploring Cranelift, we dive into ISLE—Cranelift’s own DSL, short for Instruction Selection or Lowering Expressions. ISLE streamlines converting Cranelift IR (clif) into MachInsts for machine code generation. Key topics include: Writing rewrite rules The Context trait for ISA-specific helpers ISLE’s build process and Rust code generation Plus, we explore ISLE’s handling of pure expressions and side-effects.
