Adjusts - -- component positions according to Ada 2005 AI-133. Note that this is only - -- called in Ada 2005 mode. The Ada 95 handling for bit order is entirely - -- contained in Freeze. - - procedure Initialize; - -- Initialize internal tables for new compilation - - procedure Set_Enum_Esize (T : Entity_Id); - -- This routine sets the Esize field for an enumeration type T, based - -- on the current representation information available for T. Note that - -- the setting of the RM_Size field is not affected. This routine also - -- initializes the alignment field to zero. - - function Minimum_Size - (T : Entity_Id; - Biased : Boolean := False) return Nat; - -- Given an elementary type, determines the minimum number of bits required - -- to represent all values of the type. This function may not be called - -- with any other types. If the flag Biased is set True, then the minimum - -- size calculation that biased representation is used in the case of a - -- discrete type, e.g. the range 7..8 gives a minimum size of 4 with - -- Biased set to False, and 1 with Biased set to True. Note that the - -- biased parameter only has an effect if the type is not biased, it - -- causes Minimum_Size to indicate the minimum size of an object with - -- the given type, of the size the type would have if it were biased. If - -- the type is already biased, then Minimum_Size returns the biased size, - -- regardless of the setting of Biased. Also, fixed-point types are never - -- biased in the current implementation. If the size is not known at - -- compile time, this function returns 0. - - procedure Check_Constant_Address_Clause (Expr : Node_Id; U_Ent : Entity_Id); - -- Expr is an expression for an address clause. This procedure checks - -- that the expression is constant, in the limited sense that it is safe - -- to evaluate it at the point the object U_Ent is declared, rather than - -- at the point of the address clause. The condition for this to be true - -- is that the expression has no variables, no constants declared after - -- U_Ent, and no calls to non-pure functions. If this condition is not - -- met, then an appropriate error message is posted. This check is applied - -- at the point an object with an address clause is frozen, as well as for - -- address clauses for tasks and entries. - - procedure Check_Size - (N : Node_Id; - T : Entity_Id; - Siz : Uint; - Biased : out Boolean); - -- Called when size Siz is specified for subtype T. This subprogram checks - -- that the size is appropriate, posting errors on node N as required. - -- This check is effective for elementary types and bit-packed arrays. - -- For other non-elementary types, a check is only made if an explicit - -- size has been given for the type (and the specified size must match). - -- The parameter Biased is set False if the size specified did not require - -- the use of biased representation, and True if biased representation - -- was required to meet the size requirement. Note that Biased is only - -- set if the type is not currently biased, but biasing it is the only - -- way to meet the requirement. If the type is currently biased, then - -- this biased size is used in the initial check, and Biased is False. - -- If the size is too small, and an error message is given, then both - -- Esize and RM_Size are reset to the allowed minimum value in T. - - function Rep_Item_Too_Early (T : Entity_Id; N : Node_Id) return Boolean; - -- Called at the start of processing a representation clause or a - -- representation pragma. Used to check that the representation item - -- is not being applied to an incomplete type or to a generic formal - -- type or a type derived from a generic formal type. Returns False if - -- no such error occurs. If this error does occur, appropriate error - -- messages are posted on node N, and True is returned. - - function Rep_Item_Too_Late - (T : Entity_Id; - N : Node_Id; - FOnly : Boolean := False) return Boolean; - -- Called at the start of processing a representation clause or a - -- representation pragma. Used to check that a representation item - -- for entity T does not appear too late (according to the rules in - -- RM 13.1(9) and RM 13.1(10)). N is the associated node, which in - -- the pragma case is the pragma or representation clause itself, used - -- for placing error messages if the item is too late. - -- - -- Fonly is a flag that causes only the freezing rule (para 9) to be - -- applied, and the tests of para 10 are skipped. This is appropriate - -- for both subtype related attributes (Alignment and Size) and for - -- stream attributes, which, although certainly not subtype related - -- attributes, clearly should not be subject to the para 10 restrictions - -- (see AI95-00137). Similarly, we also skip the para 10 restrictions for - -- the Storage_Size case where they also clearly do not apply, and for - -- Stream_Convert which is in the same category as the stream attributes. - -- - -- If the rep item is too late, an appropriate message is output and - -- True is returned, which is a signal that the caller should abandon - -- processing for the item. If the item is not too late, then False - -- is returned, and the caller can continue processing the item. - -- - -- If no error is detected, this call also as a side effect links the - -- representation item onto the head of the representation item chain - -- (referenced by the First_Rep_Item field of the entity). - -- - -- Note: Rep_Item_Too_Late must be called with the underlying type in - -- the case of a private or incomplete type. The protocol is to first - -- check for Rep_Item_Too_Early using the initial entity, then take the - -- underlying type, then call Rep_Item_Too_Late on the result. - - function Same_Representation (Typ1, Typ2 : Entity_Id) return Boolean; - -- Given two types, where the two types are related by possible derivation, - -- determines if the two types have the same representation, or different - -- representations, requiring the special processing for representation - -- change. A False result is possible only for array, enumeration or - -- record types. - - procedure Validate_Unchecked_Conversion - (N : Node_Id; - Act_Unit : Entity_Id); - -- Validate a call to unchecked conversion. N is the node for the actual - -- instantiation, which is used only for error messages. Act_Unit is the - -- entity for the instantiation, from which the actual types etc. for this - -- instantiation can be determined. This procedure makes an entry in a - -- table and/or generates an N_Validate_Unchecked_Conversion node. The - -- actual checking is done in Validate_Unchecked_Conversions or in the - -- back end as required. - - procedure Validate_Unchecked_Conversions; - -- This routine is called after calling the backend to validate - -- unchecked conversions for size and alignment appropriateness. - -- The reason it is called that late is to take advantage of any - -- back-annotation of size and alignment performed by the backend. - - procedure Validate_Address_Clauses; - -- This is called after the back end has been called (and thus after the - -- alignments of objects have been back annotated). It goes through the - -- table of saved address clauses checking for suspicious alignments and - -- if necessary issuing warnings. - -end Sem_Ch13; -- cgit v1.2.3
