Hi, Thanks for your quick reply. >> I think you should use altivec_lvx_v4si_2op_si instead? I will look into this. I had used v4si_internal as this was generated in older versions (<gcc-6.4)
>> And the same needs to be done for v8hi, v16qi, v4sf, maybe more? I did observe some other testcase failures for 32-bit, I will look at these instructions as well. Best Regards, Kaushik M. Phatak
