Hi Guy, Thanks a lot for the clarification. I tried using the triple for SPIR as $ clang -x cl -fno-builtin -emit-llvm -c -Xclang -triple -Xclang spir-unknown-unknown Simple_Kernel.cl However I get the following error. error: unknown target triple 'spir-unknown-unknown', please use -triple or -arch I also tried with triple nvptx-unknown-unknown clang -x cl -fno-builtin -emit-llvm -S -Xclang -triple -Xclang nvptx-unknown-unknown Simple_Kernel.cl Then I get following...

...ang -cc1". You can see that if you add the -v option. I'm sure there is someone here who can explain it better than I... Anyhow, I think you better use clang -cc1. Make sure -cc1 is the first command line option you use. $ clang -cc1 -fno-builtin -emit-llvm-bc -triple spir-unknown-unknown Simple_Kernel.cl -o Simple_Kernel.bc should work for you.
