[LLVMdev] Converting a i32 pointer to a vector of i32 ( C array to LLVM vector)

[James Courtier-Dutton]

If what you are saying is that you know the array of i32 will always be 10
entries, make the function use a constant limit=10 to the loop.
I.e Make the loop limit a constant and not a variable.
