In 2 day you can just program in OpenCL with ROCm 1.4

Is is possible to use CLOC to compile OpenCL kernels that can be used with either a ROCm platform (with NVIDIA Fiji GPU) or with the older AMD Catalyst drivers on Linux?
Before knowing about CLOC, I was thinking to to compile OpenCL kernels with Clang/LLVM and the libclc (http://libclc.llvm.org/) library. But I kind of gave up on that idea after multiple trials, as I could not find a way to use the GCN assembly generated from the Clang/LLVM AMD GCN code generator to assemble a binary that could be loaded by the OpenCL function clCreateProgramWithBinary.
Thanks in advance!

Thats very good!
And what about using the GCN assembly generated from OpenCL kernels with ROCm?
I'm applying specialized optimization strategies to LLVM IR representing OpenCL kernels, and I would like to use the output of those transformations with ROCm (so that I can generate the binaries that will execute on the GPU).
Do you have an idea on how to do this?
We will support the same compiler backend we use in HCC AMDGPU compiler, so we will have support for Assembly support. This will be complete CLANG/LLVM code path that emits GCN ISA binary.

Because I'm correctly doing experiments in the context of university research using LLVM and I would like to have AMD GPUs represented in the paper, other than only NVIDIA GPUs.
Can you take a look at this? https://github.com/RadeonOpenCompute/ROCm/issues/61
Thanks for your time.
