compilation of large OpenCL C program

Accelerated Computing CUDA CUDA Programming and Performance

Hello,

I have a 4000 line, 147KB OpenCL C program that I have removed all errors from. Now when it is compiling, it takes a very long time (much longer than a 25KB program). In fact, I have never seen it return from compilation yet.
Has there been any testing on the parser and code generator for such a large program?

(Note: the 25KB program only takes 268ms to compile)

I have attached a sample 92KB program. This compiles under gcc if you take out the__kernel and __global qualifiers. The names have been changed to try and protect our intellectual property (actually we were trying to compress the program to see if that helped).
generated.cu (91.2 KB)

Update: We found that the program has cycles in the dependency graph. The OpenCL compiler gives no error, it just sits there compiling forever.
