Summary
🤩
Rockstar🎓
Top SchoolEli Friedman is a CS PhD student at the University of Utah with seven years of software engineering and research experience focused on compilers and low-level systems. He has contributed to the prominent LLVM/Clang codebase, improving AArch64 codegen heuristics and fixing platform-specific issues such as ARM64EC and MSVC-related constexpr bugs. Eli blends academic research—through REUs and multiple research assistant positions—with practical engineering, having worked at Qualcomm Innovation Center on production compiler problems. Based in Salt Lake City, he teaches discrete mathematics and maintains an active technical presence via his personal site and GitHub. Colleagues describe him as someone who surfaces subtle correctness and alignment issues that materially improve compiler behavior.

llvm/llvm-project
Apr 2022 - Aug 2022
The LLVM Project is a collection of modular and reusable compiler and toolchain technologies.
Role in this project:
Back-end Developer
Back-end DeveloperContributions:1315 reviews, 4 commits, 120 PRs in 4 months
Contributions summary:Eli contributed to the LLVM project by addressing compiler-related issues within the AArch64 architecture. They focused on improving the compiler's heuristics for folding "lsl" operations into load/store instructions, specifically for AArch64. Furthermore, they addressed compilation problems related to ARM64EC mode by fixing preprocessor checks in intrin.h and arm_acle.h. Finally, they made contributions to the clang compiler, specifically related to MSVC and fixing a bug related to constexpr values, and also provided improvements in alignment.

Role in this project:Back-end Developer & Compiler Engineer
Back-end Developer & Compiler EngineerContributions:11 commits in 8 months
Contributions summary:Eli primarily focuses on improving the Clang compiler, specifically addressing issues related to code generation and optimization. Their contributions include fixing type issues in intrinsics for specific architectures (ARM64), making string literal initialization an rvalue to simplify expression evaluation, and correcting compiler behavior related to compound literals and array initializations. These changes aim to improve compiler correctness and potentially performance. The user also updated comments and comments in CGExprConstant.cpp.
