This clears the memory used for the Clang AST before we run LLVM passes. https://llvm-compile-time-tracker.com/compare.php?from=d0a5f61c4f6fccec87fd5207e3fcd9502dd59854&to=b7437fee79e04464dd968e1a29185495f3590481&stat=max-rss shows significant memory savings with no slowdown (in fact -O0 slightly speeds up). For more background, see https://lists.llvm.org/pipermail/cfe-dev/2021-September/068930.html. Turn this off for the interpreter since it does codegen multiple times. Relanding with fix for -print-stats: D111973 Relanding with fix for plugins: D112190 If you'd like to use this even with plugins, consider using the features introduced in D112096. This can be turned off with -Xclang -no-clear-ast-before-backend. Differential Revision: https://reviews.llvm.org/D111270 |

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