2004-07-06 Vincent Celier <celier@gnat.com> * vms_conv.ads: Minor reformatting. Alphabetical order for enumerated values of type Command_Type, to have the command in alphabetical order for the usage. * vms_conv.adb (Process_Argument): Set Keep_Temporary_Files to True for the special qualifier /KEEP_TEMPORARY_FILES (minimum 6 characters). * gnat_ugn.texi: Document new switch -dn for the GNAT driver. * makegpr.adb (Global_Archive_Exists): New global Boolean variable (Add_Archive_Path): Only add the global archive if there is one. (Build_Global_Archive): Set Global_Archive_Exists depending if there is or not any object file to put in the global archive, and don't build a global archive if there is none. (X_Switches): New table (Compile_Link_With_Gnatmake): Pass to gnatmake the -X switches stored in the X_Switches table, if any. (Initialize): Make sure the X_Switches table is empty (Scan_Arg): Record -X switches in table X_Switches * opt.ads (Keep_Temporary_Files): New Boolean flag, defaulted to False. * make.adb: Minor comment fix * gnatname.adb (Gnatname): When not on VMS, and gnatname has been invoked with directory information, add the directory in front of the path. * gnatchop.adb (Gnatchop): When not on VMS, and gnatchop has been invoked with directory information, add the directory in front of the path. * gnatcmd.adb (Delete_Temp_Config_Files): Only delete temporary files when Keep_Temporary_Files is False. (GNATCmd): When not on VMS, and the GNAT driver has been invoked with directory information, add the directory in front of the path. When not on VMS, handle new switch -dn before the command to set Keep_Temporary_Files to True. (Non_VMS_Usage): Use lower case for the non VMS usage: this is valid everywhere. * gnatlink.adb (Gnatlink): When not on VMS, and gnatlink has been invoked with directory information, add the directory in front of the path. 2004-07-06 Thomas Quinot <quinot@act-europe.fr> * snames.ads, snames.adb (Name_Stub): New name for the distributed systems annex. * rtsfind.ads: New RTE TC_Object, for DSA/PolyORB.

Change terminology in comments primitive type => elementary type. 2004-07-06 Ed Schonberg <schonberg@gnat.com> PR ada/15602 * sem_ch7.adb (Unit_Requires_Body): For a generic package, the formal parameters do not impose any requirements on the presence of a body. 2004-07-06 Ed Schonberg <schonberg@gnat.com> PR ada/15593 * sem_ch12.adb (Analyze_Package_Instantiation): If the generic is not a compilation unit and is in an open scope at the point of instantiation, assume that a body may be present later. 2004-07-06 Ed Schonberg <schonberg@gnat.com> * sem_ch13.adb (Analyze_Attribute_Definition_Clause, case 'Size): Improve error message when specified size is not supported. * sem_ch6.adb (Maybe_Primitive_Operation): A library-level subprogram is never a primitive operation.

-- This package does front-end layout of types and objects. 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.

|
|
-- 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.

|
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.
