This function replaces a call to `__move_assign` (internal function) with two calls to public member functions (`resize` and `erase`). The order of calls is chosen for the best performance. This change is required to [turn on ASan string annotations for short strings](https://github.com/llvm/llvm-project/pull/75882) (Short String Optimization - SSO). The `std::basic_string` class's `void __move_assign(basic_string&& __str, size_type __pos, size_type __len)` function operates on uninitialized strings, where it is reasonable to assume that the memory is not poisoned. However, in `sstream` this function is applied to existing strings that already have poisoned memory. String ASan annotations turned on here: https://github.com/llvm/llvm-project/pull/72677 |

The LLVM Compiler Infrastructure
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.
Getting the Source Code and Building LLVM
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.
Getting in touch
Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.
The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
