29 -- The Par function and its subunits contains all the parsing routines
30 -- for the top down recursive descent parser that constructs the parse tree
32 with Types
; use Types
;
34 function Par
(Configuration_Pragmas
: Boolean) return List_Id
;
35 -- Top level parsing routine. There are two cases:
37 -- If Configuration_Pragmas is False, Par parses a compilation unit in the
38 -- current source file and sets the Cunit, Cunit_Entity and Unit_Name fields
39 -- of the units table entry for Current_Source_Unit. On return the parse tree
40 -- is complete, and decorated with any required implicit label declarations.
41 -- The value returned in this case is always No_List.
43 -- If Configuration_Pragmas is True, Par parses a list of configuration
44 -- pragmas from the current source file, and returns the list of pragmas.
