The overloaded `operator&` caused non-conforming behavior when - using `operator==` to compare "addresses" of proxy reference objects, and - relying on the exact type of `&ref`. No deprecation warning is added, becaue it should be portable to write `&ref` where `ref` is a proxy reference variable, and this patch just corrects the behavior. `__bit_const_reference::operator&` is kept, because when one defines `_LIBCPP_ABI_BITSET_VECTOR_BOOL_CONST_SUBSCRIPT_RETURN_BOOL` to make the libc++ implementation strategy conforming, the `operator&` will never be exposed to users.
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.
