bad identification of the CPU pentium dual core ( penryn instead of core2 )
lvm 3.7.0 treats pentium dual core ( cpu family 6 model 23 ) as "penryn"
cpu, which triggers a serious bug :
- crashs in openGL programs when llvm is used by mesa package, llvm will
produces binary code with SSE4 instructions, which is not compatible
with pentium dual core, because this CPU doesn't support SSE4
instructions ( bad cpu opcodes ),
with llvm 3.6.2 this bug doesn't

[LLVMdev] Set up ExecutionEngine according to actual machine capabilities
I am currently setting up my Module with
module->setTargetTriple(llvm::sys::getProcessTriple()
#ifdef _WIN32
+ "-elf"
#endif
);
And my ExecutionEngine with
llvm::EngineBuilder(std::move(module))
.setErrorStr(&err)
.setMCPU(llvm::sys::getHostCPUName())
