This interface defines the size and alignment information that is needed by the C back-end. Units are in BITS. 

VAR
  (* alignment of generic things of the given size with typical defaults *)

  a64: INTEGER; (* := 64 *)
  a32: INTEGER; (* := 32 *)
  a16: INTEGER; (* := 16 *)
  a8: INTEGER;  (* := 8 *)

  minAlignment: INTEGER; (* := 8 *)
  recAlignment: INTEGER; (* := 8 *)
  arrayAlignment: INTEGER; (* := 8 *)

  (* type-dependent size/alignment, with typical defaults *)

  ptrA: INTEGER; (*  = a32; *)
  ptrS: INTEGER; (* = 32; *)
  realA: INTEGER; (* = a32; *)
  realS: INTEGER; (* = 32; *)
  longRealA: INTEGER; (* = a64; *)
  longRealS: INTEGER; (* = 64; *)
  intA: INTEGER; (* = a32; *)
  intS: INTEGER; (* = 32; *)
  longintA: INTEGER; (* = a64; *)
  longintS: INTEGER; (* = 64; *)
  wideCharA: INTEGER; (* = 16 *)
  wideCharS: INTEGER; (* = 16 *)

  target: TEXT;  (* name of current target *)
Support for registering/looking up targets 

TYPE
  TargetInitProc = PROCEDURE() RAISES {};
  (* one of these sets the above variables appropriately *)

PROCEDURE RegisterTarget(t: TEXT; p: TargetInitProc) RAISES {};
associate 'p' with target named 't'. 

PROCEDURE LookupTarget(
    t: TEXT;
    VAR (*out*) rp: REF TargetInitProc): BOOLEAN RAISES {};
look up 't' and return TRUE and set 'p' if found, else return FALSE. 

TYPE
  Iter <: REFANY;

PROCEDURE NewIter(): Iter RAISES {};
Create an iterator on the registered targets. 

PROCEDURE Next(
    iter: Iter;
    VAR (*out*) t: TEXT;
    VAR (*out*) rp: REF TargetInitProc
    ): BOOLEAN RAISES {};
Return the next target, or FALSE if exhausted.
