From 3dea30d912959b957808b0c114298ca3c6200d45 Mon Sep 17 00:00:00 2001 From: Richard Smith Date: Thu, 6 Jul 2017 21:05:56 +0000 Subject: [PATCH] Reject attempts to build a module without -fmodules, rather than silently doing weird things. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@307316 91177308-0d34-0410-b5e6-96231b3b80d8 --- .../clang/Basic/DiagnosticFrontendKinds.td | 2 ++
