-       N_Extended_Return_Statement by transforming the statements into a
-       block, and (indirectly) calling Expand_Cleanup_Actions on the block.
-       It's too hard for Expand_Cleanup_Actions to operate directly on the
-       N_Extended_Return_Statement, because it has a different structure than
-       the other node kinds that Expand_Cleanup_Actions.
-       * exp_util.adb (Requires_Cleanup_Actions): Add support for
-       N_Extended_Return_Statement.  Change "when others => return False;" to

-       handles.  Use named notation where appropriate.

-       to be used as the child process of a call to fork().  However, execvp
-       might actually return in some cases, for instance when attempting to
-       run a 32-bit binary on a 64-bit Linux distribution when the

-       legal in the enclosing instantiation.  This optimisation may be
-       applicable elsewhere, and it also removes spurious errors that

-
-2017-04-25  Bob Duff  <duff@adacore.com>
-
-       * sem_prag.adb (No_Return): Give an error if the pragma applies
-       to a body. Specialize the error for the specless body case,
-       as is done for (e.g.) pragma Convention.
-       * debug.adb: Add switch -gnatd.J to disable the above legality
-       checks. This is mainly for use in our test suite, to avoid

-       be useful to customers. Under this switch, if a pragma No_Return
-       applies to a body, and the procedure raises an exception (as it
-       should), the pragma has no effect. If the procedure does return,

-
-       * exp_ch6.adb (Expand_Actuals): This is the

-       some cases, rewrote N, but then set N to Original_Node(N). So
-       the node returned in N had no Parent. The caller continued
-       processing of this orphaned node. In some cases that caused a
-       crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
-       and trips over the Empty Parent). The solution is to make N an
-       'in' parameter.  Instead of rewriting it, return the list of
-       post-call actions, so the caller can do the rewriting later,
-       after N has been fully processed.
-       (Expand_Call_Helper): Move most of Expand_Call here. It has
-       too many premature 'return' statements, and we want to do the
-       rewriting on return.
-       (Insert_Post_Call_Actions): New procedure to insert the post-call
-       actions in the appropriate place. In the problematic case,
-       that involves rewriting N as an Expression_With_Actions.
-       (Expand_Call): Call the new procedures Expand_Call_Helper and
-       Insert_Post_Call_Actions.
-

-       enable by the -dp switch, or by modifying the Do_Old and Do_New
-       etc. flags and rebuilding. Experimental code is included to
-       compare the results of the old and new algorithms.
-       * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
-       can have multiple of these tables, so the old and new algorithms
-       can coexist.
-       * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
-       parameter of type array. This avoids the global variable, and
-       allows bounds checking (which is normally defeated by the tables
-       packages). It also ensures that the Elab_Order is read-only
-       to Bindgen.
-       * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
-       subprograms that need it, as above.

+       subprogram instantiation, now that the enclosing wrapper package
+       carries an explicit freeze node. THis prevents freeze nodes for the
+       subprogram for appearing in the wrong scope. This is relevant when the
+       generic subprogram has a private or incomplete formal type and the
+       instance appears within a package that declares the actual type for the
+       instantiation, and that type has itself a delayed freeze.
+
+2017-12-15  Patrick Bernardi  <bernardi@adacore.com>
+
+       * doc/gnat_ugn/gnat_and_program_execution.rst: Removed references to
+       the environment variable GNAT_STACK_LIMIT from the Stack Overflow
+       Checking section as it is no longer used by any of our supported
+       targets.

+       in particular a workaround with locks priority ceiling where a higher
+       priority task is allowed to lock a lower ceiling priority lock. This
+       also fixes the scheduling of FIFO tasks when the priority of a task is

+       * sem_eval.adb (Eval_Concatenation): Default initialize Folded_Val,

+       used all over the compiler front end, but that's too much trouble for
+       now. If we did that, we might want to rename:

+       For parameters of type Valid_Name_Id, remove some redundant tests,

+       as a predefined op and occupies the same predefined slot as
+       equality. A call to it is transformed into a call to its alias,

+       tables used in conjunction with entity and itype replication.

+
+2017-04-27  Ed Schonberg  <schonberg@adacore.com>

+       Minor reformatting.
+
+2017-04-25  Bob Duff  <duff@adacore.com>
+
+       * sem_prag.adb (No_Return): Give an error if the pragma applies
+       to a body. Specialize the error for the specless body case,
+       as is done for (e.g.) pragma Convention.
+       * debug.adb: Add switch -gnatd.J to disable the above legality
+       checks. This is mainly for use in our test suite, to avoid
+       rewriting a lot of illegal (but working) code.  It might also
+       be useful to customers. Under this switch, if a pragma No_Return
+       applies to a body, and the procedure raises an exception (as it
+       should), the pragma has no effect. If the procedure does return,
+       execution is erroneous.
+
+2017-04-25  Bob Duff  <duff@adacore.com>
+
+       * exp_ch6.adb (Expand_Actuals): This is the
+       root of the problem. It took N as an 'in out' parameter, and in
+       some cases, rewrote N, but then set N to Original_Node(N). So
+       the node returned in N had no Parent. The caller continued
+       processing of this orphaned node. In some cases that caused a
+       crash (e.g. Remove_Side_Effects climbs up Parents in a loop,
+       and trips over the Empty Parent). The solution is to make N an
+       'in' parameter.  Instead of rewriting it, return the list of
+       post-call actions, so the caller can do the rewriting later,
+       after N has been fully processed.
+       (Expand_Call_Helper): Move most of Expand_Call here. It has
+       too many premature 'return' statements, and we want to do the
+       rewriting on return.
+       (Insert_Post_Call_Actions): New procedure to insert the post-call
+       actions in the appropriate place. In the problematic case,
+       that involves rewriting N as an Expression_With_Actions.
+       (Expand_Call): Call the new procedures Expand_Call_Helper and
+       Insert_Post_Call_Actions.
+
+2017-04-25  Ed Schonberg  <schonberg@adacore.com>
+

+
+       * exp_ch5.adb (Replace_Target): When rewriting the RHS, preserve

+       enable by the -dp switch, or by modifying the Do_Old and Do_New
+       etc. flags and rebuilding. Experimental code is included to
+       compare the results of the old and new algorithms.
+       * binde.ads: Use GNAT.Dynamic_Tables instead of Table, so we
+       can have multiple of these tables, so the old and new algorithms
+       can coexist.
+       * bindgen.ads (Gen_Output_File): Pass Elab_Order as an 'in'
+       parameter of type array. This avoids the global variable, and
+       allows bounds checking (which is normally defeated by the tables
+       packages). It also ensures that the Elab_Order is read-only
+       to Bindgen.
+       * bindgen.adb: Pass Elab_Order as an 'in' parameter to all
+       subprograms that need it, as above.
+       * debug.adb: Document new -dp switch. Modify doc of old -do
+       switch.
+       * gnatbind.adb (Gnatbind): Make use of new interfaces to Binde
+       and Bindgen.  Move writing of closure (-R and -Ra switches)
+       to Binde; that's more convenient.
+
+2017-01-13  Ed Schonberg  <schonberg@adacore.com>
+
+       * sem_ch6.adb (Analyze_Expression_Function): If the expression
