[clang] Support member function poiners in Decl::getFunctionType() (#125077) This seems consistent with the documentation, which claims it: ``` /// Looks through the Decl's underlying type to extract a FunctionType /// when possible. Will return null if the type underlying the Decl does not /// have a FunctionType. const FunctionType *getFunctionType(bool BlocksToo = true) const; ``` Note: This patch rewords this doc comment to clarify it includes various function pointer types. Without this, attaching attributes (which use `HasFunctionProto`) to member function pointers errors with: ``` error: '<attr>' only applies to non-K&R-style functions ``` ...which does not really make sense, since member functions are not K&C functions. With this change the Arm SME TypeAttrs work correctly on member function pointers. Note, however, that not all attributes work correctly when applied to function pointers or member function pointers. For example, `alloc_align` crashes when applied to a function pointer (on truck): https://godbolt.org/z/YvMhnhKfx (as it only expects a `FunctionDecl` not a `ParmVarDecl`). The same crash applies to member function pointers (for the same reason).
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.
