Detailed Description

   Immediate use linking structure.  This structure is used for maintaining
   a doubly linked list of uses of an SSA_NAME.  

Field Documentation

union { ... } ssa_use_operand_d::loc
     Immediate uses for a given SSA name are maintained as a cyclic
     list.  To recognize the root of this list, the location field
     needs to point to the original SSA name.  Since statements and
     SSA names are of different data types, we need this union.  See
     the explanation in struct immediate_use_iterator_d.
