Re: CMakeLists.txt in libobjc2

[David Chisnall]

Hi Mathias,

They disable building the LLVM optimisations for LLVM > 3.3.  This is because 
LLVM APIs change quite frequently and they most likely won't build.  I think 
the thing you need to set is LLVM_OPTS=yes (check ccmake - it's documented), if 
you want to try building them.  Note that this doesn't affect the runtime 
itself, it just relates to the extra GNUstep-runtime-specific optimisations 
that can be built as an LLVM plugin.
