The following should really be moved to a Target package Java_VM : constant Boolean := False; -- Set true when compiling the JGNAT tool chain (compiler, gnatmake, etc) --------------------- -- HOST Parameters -- --------------------- Gnat_VMSp : Integer; pragma Import (C, Gnat_VMSp, "__gnat_vmsp"); OpenVMS : Boolean := Gnat_VMSp /= 0; -- Set True for OpenVMS host. See also OpenVMS target boolean in -- 5vsystem.ads and OpenVMS_On_Target boolean in Targparm. This is -- not a constant, because it can be modified by -gnatdm. Normalized_CWD : constant String := "./"; -- Normalized string to access current directory Max_Line_Length : constant := Types.Column_Number'Pred (Types.Column_Number'Last); -- Maximum source line length. By default we set it to the maximum -- value that can be supported, which is given by the range of the -- Column_Number type. We subtract 1 because need to be able to -- have a valid Column_Number equal to Max_Line_Length to represent -- the location of a "line too long" error. -- 200 is the minimum value required (RM 2.2(15)). The value set here -- can be reduced by the explicit use of the -gnatyM style switch. Max_Name_Length : constant := 1024; -- Maximum length of unit name (including all dots, and " (spec)") and -- of file names in the library, must be at least Max_Line_Length, but -- can be larger. Max_Instantiations : constant := 4000; -- Maximum number of instantiations permitted (to stop runaway cases -- of nested instantiations). These situations probably only occur in -- specially concocted test cases. Tag_Errors : constant Boolean := False; -- If set to true, then brief form error messages will be prefaced by -- the string "error:". Used as default for Opt.Unique_Error_Tag. Exclude_Missing_Objects : constant Boolean := True; -- If set to true, gnatbind will exclude from consideration all -- non-existent .o files. Max_Debug_Name_Length : constant := 256; -- If a generated qualified debug name exceeds this length, then it -- is automatically compressed, regardless of the setting of the -- Compress_Debug_Names switch controlled by -gnatC. end Hostparm;
