New Revision: 167528

URL: http://llvm.org/viewvc/llvm-project?rev=167528&view=rev
Log:
Add -fno-rtti info explicitly, fixing PR14198, while waiting for PR14200 to be
fixed.  The issue here is that when compiling with ENABLE_LLVM_PLUGINS defined,
the file llvm/Support/PluginLoader.h is included, and this file defines a global
variable
  static cl::opt<PluginLoader, false, cl::parser<std::string> >
    LoadOpt("load", cl::ZeroOrMore, cl::value_desc("pluginfilename"),
            cl::desc("Load the specified plugin"));
If dragonegg is compiled with RTTI, then the vtable for this global may refer to
RTTI for the cl::opt class (when compiling with clang on darwin) causing linking
to fail as LLVM is built without RTTI.
