Forgot to send to llvm-commits.

Is the entire AMDIL back-end coming to LLVM ToT?
[Villmow, Micah] Yes, it is going through internal code review now. However, it will be posted for LLVM 2.9
first as that is what we are building against internally. After that, when I get time as I'm pretty busy, I will
update it for TOT.

Awesome!

How will this integrate with the AMD APP SDK?  From what I understand, CAL (and the ability to load/execute AMDIL) is deprecated as of AMD APP SDK 2.5.  Is this going to somehow integrate with the AMD OpenCL implementation?
[Villmow, Micah] All I can say is that this is outside of the scope of the APP SDK. This is mainly to allow others to take advantage of targeting AMDIL from their own compilers and to see how
we implemented things using LLVM for a non-x86 like target.

So assuming I generate AMDIL using this back-end, then what?  How can I execute it on real AMD hardware?
[Villmow, Micah] One way is to create an OpenCL binary using the output of AMDIL and load it into OpenCL. Another approach is to write a small runtime shim that converts from a compilation unit containing multiple kernels into single kernel per compilation unit and then use the CAL API to generate a CAL binary.  Our first step is to get the source code out there, and then based on feedback see what the next step can be to make it more useful.
