If SSA facilitates constant propagation - then give an example of it Next edit →
Line 32: [[Compiler optimization]] algorithms that are either enabled or strongly enhanced by the use of SSA include: * [[Constant ~~propagation~~folding]] – conversion of computations from runtime to compile time, e.g. treat the instruction <code>a=34+5;</code> as if it were <code>a=17;</code> [[Value range propagation]]<ref>[http://llvm.org/devmtg/2007-05/05-Lewycky-Predsimplify.pdf value range propagation]</ref> – precompute the potential ranges a calculation could be, allowing for the creation of branch predictions in advance * [[Sparse conditional constant propagation]] – range-check some values, allowing tests to predict the most likely branch
