| -- Add a dependency on a non-source file. This is used internally for the |
| -- preprocessing data file and the preprocessing definition file, and also |
| -- externally for non-temporary configuration pragmas files. |
| |
| procedure Add_Dependencies; |
| -- Add dependencies on the preprocessing data file and the preprocessing |
| -- definition files, if any, and the non-temporary configuration pragmas |
| -- files, if any. |
| |
| procedure Check_Symbols; |
| -- Check if there are preprocessing symbols on the command line and set |
| -- preprocessing if there are some: all files are preprocessed with these |
| -- symbols. This procedure should not be called if there is a preprocessing |
| -- data file specified on the command line. Instead a call should be made |
| -- to Parse_Preprocessing_Data_File. |
| |
| procedure Parse_Preprocessing_Data_File (N : File_Name_Type); |
| -- Parse a preprocessing data file, specified with a -gnatep= switch |
| |
| procedure Prepare_To_Preprocess |
| (Source : File_Name_Type; |
| Preprocessing_Needed : out Boolean); |
| -- Prepare, if necessary, the preprocessor for a source file. If the source |
| -- file needs to be preprocessed, Preprocessing_Needed is set to True. |
| -- Otherwise, Preprocessing_Needed is set to False and no preprocessing |
| -- needs to be done. |
| |
| procedure Process_Command_Line_Symbol_Definitions; |
| -- Check symbol definitions that have been added by calls to procedure |
| -- Add_Symbol_Definition and stored as pointers to string, and put them in |
| -- a table. The reason the definitions were stored as pointer to strings is |
| -- that the name table is not yest initialized when we process the command |
| -- line switches. These symbol definitions will be later used in |
| -- the call to Prepare_To_Preprocess. |
