Reverts parts of https://reviews.llvm.org/D17183, but keeps the resetDataLayout() API and adds an assert that checks that datalayout string and user label prefix are in sync. Approach 1 in https://reviews.llvm.org/D17183#2653279 Reduces number of TUs build for 'clang-format' from 689 to 575. I also implemented approach 2 in D100764. If someone feels motivated to make us use DataLayout more, it's easy to revert this change here and go with D100764 instead. I don't plan on doing more work in this area though, so I prefer going with the smaller, more self-consistent change. Differential Revision: https://reviews.llvm.org/D100776
//===----------------------------------------------------------------------===// // 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.llvm.org/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
