Detailed Description
Represents phi nodes for memory accesses.
These have the same semantic as regular phi nodes, with the exception that only one phi will ever exist in a given basic block. Guaranteeing one phi per block means guaranteeing there is only ever one valid reaching MemoryDef/MemoryPHI along each path to the phi node. This is ensured by not allowing disambiguation of the RHS of a MemoryDef or a MemoryPhi's operands. That is, given if (a) { store a store b } it must be transformed into if (a) { 1 = MemoryDef(liveOnEntry) store a 2 = MemoryDef(1) store b } and not if (a) { 1 = MemoryDef(liveOnEntry) store a 2 = MemoryDef(liveOnEntry) store b } even if the two stores do not conflict. Otherwise, both 1 and 2 reach the end of the branch, and if there are not two phi nodes, one will be disconnected completely from the SSA graph below that point. Because MemoryUse's do not generate new definitions, they do not have this issue.
