[LLVMdev] Compilation problem with JIT/Interpreter

[Jerome GORIN]

Thank very much for this answer,
so my last question will be: is it possible to use the LLVM JIT on a PS3
with Yellow Dog 6.2 distribution, instead of the LLVM interpreter, by using
the PPE as it seems to be similar to 64-bit PowerPC processors?
