Most of the properties of memset_pattern16 can be now covered by the generic attributes and inferred by InferFunctionAttrs. The only exceptions are: - We don't yet have a writeonly attribute for the first argument. - We don't have an attribute for modeling the access size facts encoded in MemoryLocation.cpp. Differential Revision: http://reviews.llvm.org/D15879 llvm-svn: 256911
