[clang-tidy] New performance linter: performance-use-std-move (#179467) This linter suggests calls to ``std::move`` when a costly copy would happen otherwise. It does not try to suggest ``std::move`` when they are valid but obviously not profitable (e.g. for trivially movable types) This is a very simple version that only considers terminating basic blocks. Further work will extend the approach through the control flow graph. It has already been used successfully on llvm/lib to submit bugs #178174, #178169, #178176, #178172, #178175, #178180, #178178, #178177, #178179, #178173 and #178167, and on the firefox codebase to submit most of the dependencies of bug https://bugzilla.mozilla.org/show_bug.cgi?id=2012658
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
