Hello,
Pocl_version 0.13 + llvm 3.8 are both VERY old. I would be surprised if half
type works there, especially in combination with 64bit ARM. I recommend you get
LLVM 6 and pocl at least 1.1, otherwise you'll experience problems.
Regards,

Subject: [pocl-devel] 【Hi】 There is Question about half2
Hi：
I write the opencl demo. In this demo , I wrote the half2 type . But it
compile it failed.
The output as below:
