-- routines to save and restore a project scan context.
with Scans; use Scans;
package Sinput.P is
procedure Clear_Source_File_Table;
-- This procedure frees memory allocated in the Source_File table (in the
-- private part of package Sinput). It should only be used when it is
-- guaranteed that all source files that have been loaded so far will not
-- be accessed before being reloaded. It is intended for tools that parse
-- several times sources, to avoid memory leaks.
function Load_Project_File (Path : String) return Source_File_Index;
-- Load the source of a project source file into memory and initialize the
-- Scans state.
procedure Reset_First;
-- Indicate that the next project loaded should be considered as the first
-- one, so that Sinput.Main_Source_File is set for this project file. This
-- is to get the correct number of lines when error finalization is called.
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. Returns False if X = No_Source_File.

-- Restore the Scans state and the values of Source and
