| ----------------------- |
| |
| -- ??? 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. |
