Detailed Description
LoadAndStorePromoter - This little helper class provides a convenient way to promote a collection of loads and stores into SSA Form using the SSAUpdater. This handles complexities that SSAUpdater doesn't, such as multiple loads and stores in one block.
Clients of this class are expected to subclass this and implement the virtual methods.

Return true if the specified instruction is in the Inst list (which was passed into the run method). Clients should implement this with a more efficient version if possible.

| virtual void llvm::LoadAndStorePromoter::replaceLoadWithValue | ( | LoadInst * | LI, |

replaceLoadWithValue - Clients can choose to implement this to get notified right before a load is RAUW'd another value.

| void LoadAndStorePromoter::run | ( | const SmallVectorImpl< Instruction * > & | Insts | ) | const |
run - This does the promotion. Insts is a list of loads and stores to promote, and Name is the basename for the PHIs to insert. After this is complete, the loads and stores are removed from the code.
