llvm-6502/test/Transforms/IndVarSimplify
Arnaud A. de Grandmaison eb9a42e8ab IndVarSimplify: do not recompute an IV value outside of the loop if :
- it is trivially known to be used inside the loop in a way that can not be optimized away
- there is no use outside of the loop which can take advantage of the computation hoisting
