be emitted. This is needed to enable ARM long calls for LTO and enable and disable it on a per-function basis. Out-of-tree projects currently using EnableARMLongCalls to emit long calls should start passing "+long-calls" to the feature string (see the changes made to clang in r241565). rdar://problem/21529937 Differential Revision: http://reviews.llvm.org/D9364 llvm-svn: 241566
