-//===-- TargetData.cpp - Data size & alignment routines --------------------==//
-//
-// This file defines target properties related to datatype size/offset/alignment
-// information.  It uses lazy annotations to cache information about how 
-// structure types are laid out and used.
-//
-// This structure should be created once, filled in if the defaults are not
-// correct and then passed around by const&.  None of the members functions
-// require modification to the object.
-//
