The result is --- to annotate the tree with information on size and alignment of types --- and objects. How much layout is performed depends on the setting of the --- target dependent parameter Backend_Layout. - -with Types; use Types; - -package Layout is - - -- The following procedures are called from Freeze, so all entities - -- for types and objects that get frozen (which should be all such - -- entities which are seen by the back end) will get layed out by one - -- of these two procedures. - - procedure Layout_Type (E : Entity_Id); - -- This procedure may set or adjust the fields Esize, RM_Size and - -- Alignment in the non-generic type or subtype entity E. If the - -- Backend_Layout switch is False, then it is guaranteed that all - -- three fields will be properly set on return. Regardless of the - -- Backend_Layout value, it is guaranteed that all discrete types - -- will have both Esize and RM_Size fields set on return (since - -- these are static values). Note that Layout_Type is not called - -- for generic types, since these play no part in code generation, - -- and hence representation aspects are irrelevant. - - procedure Layout_Object (E : Entity_Id); - -- E is either a variable (E_Variable), a constant (E_Constant), - -- a loop parameter (E_Loop_Parameter), or a formal parameter of - -- a non-generic subprogram (E_In_Parameter, E_In_Out_Parameter, - -- or E_Out_Parameter). This procedure may set or adjust the - -- Esize and Alignment fields of E. If Backend_Layout is False, - -- then it is guaranteed that both fields will be properly set - -- on return. If the Esize is still unknown in the latter case, - -- it means that the object must be allocated dynamically, since - -- its length is not known at compile time. - - -- The following are utility routines, called from various places - - procedure Adjust_Esize_Alignment (E : Entity_Id); - -- E is the entity for a type or object. This procedure checks that the - -- size and alignment are compatible, and if not either gives an error - -- message if they cannot be adjusted or else adjusts them appropriately. - - procedure Set_Discrete_RM_Size (Def_Id : Entity_Id); - -- Set proper RM_Size for discrete size, this is normally the minimum - -- number of bits to accommodate the range given, except in the case - -- where the subtype statically matches the first subtype, in which - -- case the size must be copied from the first subtype. For generic - -- types, the RM_Size is simply set to zero. This routine also sets - -- the Is_Constrained flag in Def_Id. - - procedure Set_Elem_Alignment (E : Entity_Id); - -- The front end always sets alignments for elementary types by calling - -- this procedure. Note that we have to do this for discrete types (since - -- the Alignment attribute is static), so we might as well do it for all - -- elementary types, since the processing is the same. - -end Layout; |
