//===----------------------------------------------------------------------===// // C Language Family Front-end //===----------------------------------------------------------------------===// Welcome to Clang. This is a compiler front-end for the C family of languages (C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM compiler infrastructure project. Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source level tools. One example of this is the Clang Static Analyzer. If you're interested in more (including how to build Clang) it is best to read the relevant web sites. Here are some pointers: Information on Clang: http://clang.llvm.org/ Building and using Clang: http://clang.llvm.org/get_started.html Clang Static Analyzer: http://clang-analyzer.llvm.org/ Information on the LLVM project: http://llvm.org/ If you have questions or comments about Clang, a great place to discuss them is on the Clang development mailing list: http://lists.cs.uiuc.edu/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/

precisely match the pattern and logic used by the GCC driver on Linux as of a recent SVN checkout. This happens to follow a *much* more principled approach. There is a strict hierarchy of paths examined, first with multilib-suffixing, second without such suffixing. Any and all of these directories which exist will be added to the library search path when using GCC. There were many places where Clang followed different paths, omitted critical entries, and worst of all (in terms of challenges to debugging) got the entries in a subtly wrong order. If this breaks Clang on a distro you use, please let me know, and I'll work with you to figure out what is needed to work on that distro. I've checked the behavior of the latest release of Ubuntu, OpenSUSE, Fedora, and Gentoo. I'll be testing it on those as well as Debian stable and unstable and ArchLinux. I may even dig out a Slackware install. No real regression tests yet, those will follow once I add enough support for sysroot to simulate various distro layouts in the testsuite. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140981 91177308-0d34-0410-b5e6-96231b3b80d8
