I think building LLVM for x86 target should solve the problem. The resulting ispc will be able to built both x86 and x86-64.
I guess the error occurs when ispc is trying to link x86 libraries, while LLVM TargetMachine is defaulted to x86-64, so the error. Though not completely sure. Let me know if building x86 LLVM doesn't solve the problem. Dmitry.
