Hi Jordan, You're right, and the driver -target option works perfectly with the SPIR triples.

Hello everyone, Thanks a lot for the help. -target nvptx worked great with llvm-3.2. However it gives error with -target spir. LLVM/Clang trunk although works good for both options ( probably because spir is still work in progress ). Thanks again. - Ankur On Thu, Jan 24, 2013 at 12:43 PM, Benyei, Guy <guy.benyei at intel.com> wrote:> Hi Jordan,**** > > You’re right, and the driver -target option works perfectly with the SPIR > triples.**** > > ** ** > > Thanks**** > > Guy Benyei**** > > [image: email_signature_guy_new2]**** > > ** ** > > *From:* Jordan Rose [mailto:jordan_rose at apple.com] > *Sent:* Wednesday, January 23, 2013 19:47 > *To:* Benyei, Guy > *Cc:* ankur deshwal; cfe-dev at cs.uiuc.edu; llvmdev at cs.uiuc.edu > *Subject:* Re: [cfe-dev] OpenCL SPIR/NVPTX code generation**** > > ** ** > > ** ** > > On Jan 23, 2013, at 4:04 , "Benyei, Guy" <guy.benyei at intel.com> wrote:**** > > > > **** > > Hi Ankur,**** > > Since you use –Xclang, the clang executable passes multiple triples to > “clang -cc1”.
