PyTorch leverages clang-tidy to auto-add std::move calls
Clang-tidy's performance rule scans PyTorch with just one false positive.
Deep Dive
PyTorch applied clang-tidy's performance-use-std-move rule to add missing std::move calls, with only one false positive in the entire codebase. The PR, submitted by Skylion007, was double-checked with Claude and Codex. The check is very conservative by default.
Key Points
- PyTorch applied clang-tidy's performance-use-std-move rule to add missing std::move calls across its codebase.
- Only one false positive was found in the entire scan, verified by Claude and Codex AI.
- The optimization reduces unnecessary object copies, improving performance in hot paths without introducing bugs.
Why It Matters
Automating C++ performance fixes at scale saves developer time and makes PyTorch faster out of the box.
