Author: dim Date: Wed Apr 11 10:21:52 2018 New Revision: 329827 URL: http://llvm.org/viewvc/llvm-project?rev=329827&view=rev Log: Document -std= values for different languages
Summary: After a remark on a FreeBSD mailing list that the clang man page did not have any list of possible values for the `-std=` flag, I have now attempted to exhaustively list those, for each available language. I also documented the default standard for each language, if there was more than one choice.
