| function Source_File_Is_Subunit (X : Source_File_Index) return Boolean; |
| -- This function determines if a source file represents a subunit. It |
| -- works by scanning for the first compilation unit token, and returning |
| -- True if it is the token SEPARATE. It will return False otherwise, |
| -- meaning that the file cannot possibly be a legal subunit. This |
| -- function does NOT do a complete parse of the file, or build a |
| -- tree. It is used in gnatmake to decide if a body without a spec |
| -- in a project file needs to be compiled or not. |
