Brian Gesiak 24910765e2 [Driver] Suggest correctly spelled driver options ... Summary: Depends on https://reviews.llvm.org/D41732. Utilities such as `opt`, when invoked with arguments that are very nearly spelled correctly, suggest the correctly spelled options: ``` bin/opt -hel opt: Unknown command line argument '-hel'. Try: 'bin/opt -help' opt: Did you mean '-help'? ``` Clang, on the other hand, prior to this commit, does not: ``` bin/clang -hel clang-6.0: error: unknown argument: '-hel' ``` This commit makes use of the new libLLVMOption API from https://reviews.llvm.org/D41732 in order to provide correct suggestions: ``` bin/clang -hel clang-6.0: error: unknown argument: '-hel', did you mean '-help'? ``` Test Plan: `check-clang` Reviewers: yamaguchi, v.g.vassilev, teemperor, ruiu, bruno Reviewed By: bruno Subscribers: bruno, jroelofs, cfe-commits Differential Revision: https://reviews.llvm.org/D41733 llvm-svn: 321917		2018-01-06 00:25:40 +00:00
