◆ addSegment()

LoadCommand & Object::addSegment ( StringRef  SegName,
uint64_t  SegVMSize 
)

Creates a new segment load command in the object and returns a reference to the newly created load command.

The caller should verify that SegName is not too long (SegName.size() should be less than or equal to 16).
