[llvm-commits] [PATCH] CMake unittests should compile without RTTI

[Frits van Bommel]

It seems that when the CMake build is configured to compile with
unittests it does so with RTTI information enabled, which causes
linker errors because it tries to link them to an RTTI-less LLVM. This
is a recent problem by the way, it worked just fine last week.

The attached patch is a quick and dirty fix for this, but I'm not sure
if it's the right approach.
Since I couldn't find any way to *enable* RTTI for LLVM in the cmake
configuration, I just assumed it should always be off.

By the way, are there no buildbots running CMake with unittests
enabled? None of them seem to have failed over this...
