Hi David,

thanks for your helpful explanation. If it's just about optimization, then I probably won't use that. I just was irritated by the term "options". As long as I still need to find out why I can't compile with clang on ARM as needed, I will try to catch every bit of information that I can get to learn more about the tools I'm trying to use.

Best regards,
Mathias

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.

Hi,

I wonder how the CMake build in libobjc2 reacts on different versions of clang.

The CMakeLists.txt of libobjc2 seems to disable some LLVM options in case any 
clang version > 3 or directly from svn is used.

What are these options and how do I enable them explicitly?

Best regards,
Mathias
