Author: Jan Svoboda Date: 2021-02-08T09:56:33+01:00 New Revision: bff6d9bb0f6d382d1d1826e997a6104bbe5ade73
URL: https://github.com/llvm/llvm-project/commit/bff6d9bb0f6d382d1d1826e997a6104bbe5ade73 DIFF: https://github.com/llvm/llvm-project/commit/bff6d9bb0f6d382d1d1826e997a6104bbe5ade73.diff LOG: [clang][cli] Report result of ParseLangArgs This patch correctly reports success/failure of `ParseLangArgs`. Besides being consistent with other `Parse` functions, this is required to make round-tripping of `LangOptions` work.
