Example code
There seems to be a bug of some kind where loads and stores in a loop body
which could be optimised into registers aren't being done so.
I've attached some example code showing the small input function and the .ll
output.
The file was compiled using; clang.exe -cc1 -O3 -emit-llvm loop.cl
