Hal Finkel 028d6e153e Fix an error in BBVectorize important for vectorizing pointer types. ... When vectorizing pointer types it is important to realize that potential pairs cannot be connected via the address pointer argument of a load or store. This is because even after vectorization, the address is still a scalar because the address of the higher half of the pair is implicit from the address of the lower half (it need not be, and should not be, explicitly computed). llvm-svn: 154735		2012-04-14 07:32:50 +00:00
