[clang-tidy] Add recursion protection in ExceptionSpecAnalyzer (#66810) Normally endless recursion should not happen in ExceptionSpecAnalyzer, but if AST would be malformed (missing include), this could cause crash. I run into this issue when due to missing include constructor argument were parsed as FieldDecl. As checking for recursion cost nothing, why not to do this in check just in case. Fixes #111436
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.
