	* alfa.adb, alfa.ads, alfa_test.adb: New files.
	* ali.adb (Known_ALI_Lines): add 'C' lines (SCO) and 'F' lines (ALFA)
	(Scan_ALI): do not issue a fatal error if parsing known lines after Xref

	* get_alfa.adb, get_alfa.ads: New files.
	* lib-writ.adb, lib-writ.ads (Write_ALI): output ALFA information if
	needed.
	* lib-xref-alfa.adb: New file.
	* lib-xref.adb, lib-xref.ads
	(Xref_Entry): redefine information needed in cross-references for ALFA.
	Push ALFA treatments in separated local package.
	(Enclosing_Subpragram_Or_Package): treat specially subprogram
	identifiers. Return entity of package body instead of spec. Return
	Empty for a scope with no location.
	(Generate_Reference): adapt to new components for ALFA information.
	Remove the need for D references on definitions.
	(Is_Local_Reference): moved to ALFA local package
	(Output_References): extract subfunction as Extract_Source_Name
	(Output_Local_References): remove procedure, replaced by filtering of
	cross-references in package ALFA and printing in Put_ALFA.
	(Write_Entity_Name): remove procedure
	* lib.adb, lib.ads (Extract_Source_Name): extract here function to
	print exact name of entity as it appears in source file
	(Unit_Ref_Table): make type public for use in Lib.Xref.ALFA
	* put_alfa.adb, put_alfa.ads: New files.
	* xref_lib.adb (Search_Xref): protect read of cross-references against
	reading other sections of the ALI file, in gnatxref
	(Search): protect read of cross-references against reading other
	sections of the ALI file, in gnatfind.
	* gcc-interface/Make-lang.in: Update dependencies.

2011-08-03  Thomas Quinot  <quinot@adacore.com>

	* sem_ch3.adb: Minor reformatting.

2011-08-03  Jose Ruiz  <ruiz@adacore.com>

	* s-inmaop-vxworks.adb (Setup_Interrupt_Mask): Do nothing instead of
	raising an exception.

2011-08-03  Ed Schonberg  <schonberg@adacore.com>

	* sem_res.adb (Set_String_Literal_Subtype): if index type is an integer
	type, always use 1 as the lower bound or string, even if lower bound of
	context is not static, to handle properly null strings in a non-static
	context.

2011-08-03  Bob Duff  <duff@adacore.com>

	* sem_prag.adb (Resolve_Aggregate): An array aggregate with 'others' is
	always legal on the right-hand side of an assignment statement; there
	is always an applicable index constraint in this case. Therefore, the
	check for Pkind = N_Assignment_Statement is now unconditional -- it
	doesn't depend on whether Is_Constrained (Typ).

+
+--  This package defines tables used to store information needed for the ALFA
+--  mode. It is used by procedures in Lib.Xref.ALFA to build the ALFA
+--  information before writing it out to the ALI file, and by Get_ALFA/Put_ALFA
+--  to read and write the text form that is used in the ALI file.
+
+with Types;      use Types;
+with GNAT.Table;
+
+package ALFA is
+
+   --  ALFA information can exist in one of two forms. In the ALI file, it is
+   --  represented using a text format that is described in this specification.
+   --  Internally it is stored using three tables ALFA_Xref_Table,
+   --  ALFA_Scope_Table and ALFA_File_Table, which are also defined in this
+   --  unit.
+
+   --  Lib.Xref.ALFA is part of the compiler. It extracts ALFA information from
+   --  the complete set of cross-references generated during compilation.
+
+   --  Get_ALFA reads the text lines in ALI format and populates the internal
+   --  tables with corresponding information.
+
+   --  Put_ALFA reads the internal tables and generates text lines in the ALI
+   --  format.
+
+   ---------------------
+   -- ALFA ALI Format --
+   ---------------------
+
+   --  ALFA information is generated on a unit-by-unit basis in the ALI file,
+   --  using lines that start with the identifying character F ("Formal").
+   --  These lines are generated if one of the -gnatd.E (SPARK generation mode)
+   --  or gnatd.F (Why generation mode) switches is set.
+
+   --  The ALFA information follows the cross-reference information, so it
+   --  needs not be read by tools like gnatbind, gnatmake etc.
+
+   --  -------------------
+   --  -- Scope Section --
+   --  -------------------
+
+   --  A first section defines the scopes in which entities are defined and
+   --  referenced. A scope is a package/subprogram declaration/body. Note that
+   --  a package declaration and body define two different scopes. Similarly, a

+
+   --    FD dependency-number filename
+
+   --      This header precedes scope information for the unit identified by
+   --      dependency number and file name. The dependency number is the index
+   --      into the generated D lines and is ones-origin (e.g. 2 = reference to
+   --      second generated D line).
+
+   --      The list of FD lines should match the list of D lines defined in the
+   --      ALI file, in the same order.
+
+   --      Note that the filename here will reflect the original name if a
+   --      Source_Reference pragma was encountered (since all line number
+   --      references will be with respect to the original file).
+
+   --      Note: the filename is redundant in that it could be deduced from the
+   --      corresponding D line, but it is convenient at least for human
+   --      reading of the ALFA information, and means that the ALFA information
+   --      can stand on its own without needing other parts of the ALI file.
+
+   --    FS . scope line type col entity
+
+   --      scope is the ones-origin scope number for the current file (e.g. 2 =
+   --      reference to the second FS line in this FD block).
+
+   --      line is the line number of the scope entity. The name of the entity
+   --      starts in column col. Columns are numbered from one, and if
+   --      horizontal tab characters are present, the column number is computed
+   --      assuming standard 1,9,17,.. tab stops. For example, if the entity is
+   --      the first token on the line, and is preceded by space-HT-space, then
+   --      the column would be column 10.
+
+   --      type is a single letter identifying the type of the entity, using
+   --      the same code as in cross-references:
+
+   --        K = package
+   --        V = function
+   --        U = procedure
+
+   --      col is the column number of the scope entity

+--  This utility program is used to test proper operation of the Get_ALFA and
+--  Put_ALFA units. To run it, compile any source file with switch -gnatd.E or
+--  -gnatd.F to get an ALI file file.ALI containing ALFA information. Then run
+--  this utility using:
+
+--     ALFA_Test file.ali
+
+--  This test will read the ALFA information from the ALI file, and use
+--  Get_ALFA to store this in binary form in the internal tables in ALFA. Then
+--  Put_ALFA is used to write the information from these tables back into text
+--  form. This output is compared with the original ALFA information in the ALI
+--  file and the two should be identical. If not an error message is output.
