+ -- be accessed before being reloaded. It is intended for tools that parse

+ 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 and
+ -- gprbuild to decide if a body without a spec in a project file needs to
+ -- be compiled or not.
