It's possible to generate IL code using OpenCL compiler from SDK. Here is how 
.
Go to SDK/bin directory and copy your opencl source file as source.cl. Then issue from command line the following instructions
./clc --emit=llvmbc source.cl -o kernel.bc
./llc -regalloc=amdil -filetype=asm -march=amdil kernel.bc -o kernel.il
( for windows users omit ./ )
Done . kernel.il is our result.
You can try to enable optimizations ( -O3 -enable-fp-mad -enable-unsafe-fp-math as options to the llc ) but it looks like the compiler doesn't use it.
On the pessimistc note, the quality of generated code doesn't look too good. I think that at the moment we have only rudimentary OpenCL compiler. Judging by the time it took ATI to get it done ( 5 months longer than others ) we can't expect good compiler any time soon.
PS. llc --versions gives Registered Targets: amdil - ATI RADEON HD4XXX series graphics cards. And yet at the same time we get information that OpenCL compiler is created for 58xx ( this argument was given as justification to low opencl performance on 48xx ).

When I have some spare time I'll verify this as intercepting llc call from libopencl isn't that hard ( and I'll try to update this "guide" ). But I can say that bit code generated by the clc didn't look bad ( clc generates also text version ). So for now i have reasonable doubts if changing clc step ( to match the one in libopencl ) will give better code.
Of course you could simply tell us what to do ( I assume some additional flags to clc ).
