LLVM Translation Validation Automated with Large Language Models and Lean
Chunhao Liao, Hongxu Xu, Xintong Zhou +2
LLVM is the cornerstone of modern compilers, but its subtle intermediate representation (IR) semantics make transformations error-prone and necessitate formal verification. Alive2,…

Leveraging Large Language Models for Generalizing Peephole Optimizations
Chunhao Liao, Hongxu Xu, Xintong Zhou +2
Peephole optimizations are a core component of modern optimizing compilers. It rewrites specific instruction into semantically equivalent but more efficient forms. In practice, cre…

LPO: Discovering Missed Peephole Optimizations with Large Language Models
Zhenyang Xu, Hongxu Xu, Yongqiang Tian +2
Peephole optimization is an essential class of compiler optimizations that targets small, inefficient instruction sequences within programs. By replacing such suboptimal instructio…
