On the other hand, I found no OpenCL implementations which are based on GCC. Do you have any idea of the reasons? I think the reason is that nobody has written such a front end. > I have this question because some devices may not have LLVM backends, but only have their backends in GCC. In such a case, a natural way is to add a new font-end into GCC, and build a kernel compiler based on the GCC compiling passes. What are the difficulties behind this idea?
