[clang-tidy] Warn on use of std::get_temporary_buffer (#176191) The STL function `std::get_temporary_buffer` was originally designed with the intent of providing a more efficient implementation than the general-purpose operator new, but no such implementation was created and the API was deprecated (in C++17) and removed (in C++20). As this function is difficult to use and provides no advantages, I think (or at least hope) that nobody actually uses it; but given that it was present in the official standard, I think tidy should be able to report its bugprone nature. (It returns uninitialized memory, which can cause subtle bugs, e.g. as in the last code example of the SEI CERT rule EXP54-CPP.)
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.
