[clang] Emit error for invalid friend functions under [temp.friend]p9 (#78083) Emits an error for friend FunctionDecls that either: * are not templates and have a requires clause * are templates, and have a constrained parameter that depends on a template parameter from an enclosing template and are not a definition. For a non-template friend function with a requires clause, if the function is not templated then the original error message indicating that such a function is disallowed is shown instead, as the function will still be rejected if a definition is added.
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.
