Cranelift

Research query: Cranelift · jobs: 2 · on-topic sources: 5 · review: Conflicted

Overview

Cranelift, a fast and modern compiler backend originally developed for WebAssembly and recently adopted as an experimental backend for Rust, has gained increasing importance due to its superior compilation speed compared to LLVM and comprehensive multi-architecture support, including x86-64, AArch64, s390x, and RISCV64. — CLIR: Liveness-Driven and Structure-Aware Fuzzing for the Cranelift Compiler (2026)

Cranelift is an optimizing compiler backend that converts a target-independent intermediate representation into executable machine code. — Cranelift (wikipedia)

CLIR: Liveness-Driven and Structure-Aware Fuzzing for the Cranelift Compiler (2026)

Our comprehensive evaluation demonstrates that CLIR substantially outperforms existing state-of-the-art baselines, detecting 8×, 24×, and 8× as many unique bugs as cranelift-fuzzgen, wasm-smith, and WASMaker, respectively, while RustSmith uncovered no bugs. (new this job) — source

Cranelift, a fast and modern compiler backend originally developed for WebAssembly and recently adopted as an experimental backend for Rust, has gained increasing importance due to its superior compilation speed compared to LLVM and comprehensive multi-architecture support, including x86-64, AArch64, s390x, and RISCV64. (new this job) — source

However, despite decades of development in compiler testing, testing Cranelift still presents unique challenges, including (1) constructing valid IR under the strict enforcement of SSA form, (2) generating sequences with sufficient computational density to stress backend components, and (3) balancing broad backend coverage with efficient root cause analysis across heterogeneous architectures.

Compile-Time Analysis of Compiler Frameworks for Query Compilation (2024)

We present a performance comparison and detailed analysis of the compile times of the JIT compilation back-ends provided by GCC, LLVM, Cranelift, and a single-pass compiler in the context of database queries. (new this job) — source

Cranelift achieves a similar run-time performance to unoptimized LLVM, but compiles just 20–35% faster and is outperformed by the single-pass compiler, which compiles code 16x faster than Cranelift at similar execution performance. (new this job) — source
