Avoid recursively instantiating importSeq. Use initializer list expansion to stamp out a single instantiation of std::tuple of the deduced sequence of types, and thread the error around that tuple type. Avoids needlessly instantiating std::tuple N-1 times. new time to compile: 0m25.985s old time to compile: 0m35.563s new obj size: 10,000kb old obj size: 12,332kb I found the slow TU by looking at ClangBuildAnalyzer results, and looked at -ftime-trace for the file in chrome://tracing to find this. Tested with: clang-cl, MSVC, and GCC. Reviewed By: martong Differential Revision: https://reviews.llvm.org/D73667 |

//===----------------------------------------------------------------------===// // 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/
