clang
C language family frontend for LLVM
The goal of the Clang project is to create a new C, C++, Objective C and Objective C++ front-end for the LLVM compiler. Features and Goals Some of the goals for the project include the following: End-User Features: Fast compiles and low memory use Expressive diagnostics GCC compatibility Utility and Applications: Modular library based architecture Support diverse clients (refactoring, static analysis, code generation, etc) Allow tight integration with IDEs Use the LLVM BSD License Internal Design and Implementation: A real-world, production quality compiler A simple and hackable code base A single unified parser for C, Objective C, C++, and Objective C++ Conformance with C/C++/ObjC and their variants

Use flags of 24.0.0_pre20260725
- +debug Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
- doc Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
- +extra Build extra tools (clangd, clang-tidy and a few more)
- ieee-long-double Use accelerated 128-bit IEEE long double ABI (ppc64le only)
- +pie Build programs as Position Independent Executables (a security hardening technique)
- +static-analyzer Install the Clang static analyzer
- test Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
- xml Add support for XML files
