Detailed Description

   This structure (of which only a singleton SA exists) is used to
   pass around information between the outof-SSA functions, cfgexpand
   and expand itself.  

Field Documentation

var_map ssaexpand::map
     The computed partitions of SSA names are stored here.  

Referenced by insert_rtx_to_part_on_edge().

bitmap ssaexpand::partition_has_default_def
     If partition I contains an SSA name that has a default def,
     bit I will be set in this bitmap.  
rtx* ssaexpand::partition_to_pseudo
     For a partition number I partition_to_pseudo[I] contains the
     RTL expression of the allocated space of it (either a MEM or
     a pseudos REG).  

Referenced by discover_nonconstant_array_refs_r(), fini_vars_expansion(), and insert_rtx_to_part_on_edge().

bitmap ssaexpand::values
     For an SSA name version V bit V is set iff TER decided that
     its definition should be forwarded.  

Referenced by get_rtx_for_ssa_name().
