Hi,
> void cpu_setup_vector_widths(cl_device_id):
This code sets up "preferred vector widths" OpenCL device information. It uses
LLVM's sys::getHostCPUFeatures call which apparently fails for your CPU.
You can either fill them manually, or just comment that code out, it's usually
not that important.
Cheers,

Subject: Re: [pocl-devel] POCL on Power9, Tegra
Hi Folks
An update. I got POCL built and running on Tegra (ARM) perfectly with CUDA
backend. Out of the box. OpenCL apps run fine too. Thats great.
Now, I’m trying on Power9 with CUDA backend using LLVM 6.0.1. I got everything
built last night. And I can certainly compile simple OpenCL apps. However, if I
try to run any of them .. I get
[root@centos7-ppc64le ~]# ./a.out
a.out: /root/pocl/lib/CL/pocl_llvm_utils.cc:179: void
cpu_setup_vector_widths(cl_device_id): Assertion `res' failed.
Aborted (core dumped)
Its not much info .. but maybe someone on this list can help me troubleshoot.
Cheers
Gaurav
