[libc++] Validate vector<bool> copy/move-assignment operators in realistic scenarios (#119817) The existing tests for `vector<bool>` copy- and move-assignment operators are limited to 3 bits only, which are inadequate to cover realistic scenarios. Most `vector<bool>` operations have code paths that are executed only when multiple storage words are involved, with each storage word typically comprising 64 bits on a 64-bit platform. Furthermore, the existing tests fail to cover all combinations `POCCA`/`POCMA`, along with different allocator equality and/or reallocation scenarios, leaving some critical code paths untested. This patch enhances the test coverage by introducing new tests covering up to 5 storage words, ensuring that partial words in the front or tail, and whole words in the middle are all properly tested. Moreover, these new tests ensure that the copy- and move-assignment operators are tested under all combinations of `POCCA`/`POCMA` and various allocator equality scenarios, both with or without reallocations.
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.
