This patch adds assertions in the getMangledNameImpl() function to ensure that the expected target attributes (TargetAttr, TargetVersionAttr, and TargetClonesAttr) are not null before they are passed to appendAttributeMangling() to prevent potential null pointer dereferences and improve the robustness of the attribute mangling process. This assertion will trigger a runtime error with a clear message in debug build if any of the expected attributes are missing, facilitating early and easier diagnosis and debugging of such issues related to attribute mangling.
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.
