en Copyright 2015 Java http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/Frontend/compiler-options-dump.cpp#16ed8dd8 Add a new driver mode to dump compiler feature and extension options.Add the ability to dump compiler option-related information to a JSON file via the -compiler-options-dump option. Specifically, it dumps the features/extensions lists -- however, this output could be extended to other information should it be useful. In order to support features and extensions, I moved them into a .def file so that we could build the various lists we care about from them without a significant increase in maintenance burden.llvm-svn: 333653 List of files: /llvm-project-15.0.7/clang/test/Frontend/compiler-options-dump.cpp Thu, 31 May 2018 13:57:09 +0000 Aaron Ballman <aaron@aaronballman.com>
