llvm-core/clang Package Details

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

General

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
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

llvm-core/clang: Set CLANG_CONFIG_FILE_USER_DIR for per-user config
This is a better way to pass dynamic flags like --sysroot when cross-compiling than sticking them directly in variables like CC. The HOME directory is overridden by Portage, so real user config won't interfere with package builds. For now, the necessary config can be set up in pre_src_unpack, but perhaps we could come up with something more formal later.

llvm-core/clang: drop llvm_prepend_path use
The hackery with PATH here is wrong and it breaks building Clang itself with a different version of Clang (which is why we're looking at rejigging how the eclass works/replacing it with llvm-r1.eclass [0]). As suggested by Matt, use LLVM_CMAKE_DIR instead so that Clang finds the right version of LLVM to build against without any sort of nonsense messing with build tooling.
