CreateCopyOfByValArgument - Make a copy of an aggregate at address specified by "Src" to address "Dst" of size "Size". Alignment information is specified by the specific parameter attribute. The copy will be passed as a byval function parameter. Sometimes what we are copying is the end of a larger object, the part that does not fit in registers.
