From d04b1b034221371c2f6a8179fea4f6cecebf2d53 Mon Sep 17 00:00:00 2001

Subject: [PATCH] soc/fsp_broadwell_de/acpi: Remove ADR from uncore object
ACPI objects can have an HID or ADR, but not both.
Remove the ADR since the HID is more relevent.

+Author: Alexandre Oliva <oliva@adacore.com>
+Date: Fri Aug 2 18:46:51 2019 +0000
+
+ rework Ada EH Machine_Occurrence deallocation
+
+ Introduce exception handler ABI #1 to ensure single release, no access
+ after release of reraised Machine_Occurrences, and no failure to
+ re-reraise a Machine_Occurrence.
+
+ Unlike Ada exceptions, foreign exceptions do not get a new
+ Machine_Occurrence upon reraise, but each handler would delete the
+ exception upon completion, normal or exceptional, save for the case of
+ a 'raise;' statement within the handler, that avoided the delete by
+ clearing the exception pointer that the cleanup would use to release
+ it. The cleared exception pointer might then be used by a subsequent
+ reraise within the same handler. Get_Current_Excep.all would also
+ expose the Machine_Occurrence to reuse by Reraise_Occurrence, even for
+ native exceptions.
+
+ Under ABI #1, Begin_Handler_v1 claims responsibility for releasing an
+ exception by saving its cleanup and setting it to Claimed_Cleanup.
+ End_Handler_v1 restores the cleanup and runs it, as long as it isn't
+ still Claimed_Cleanup (which indicates an enclosing handler has
+ already claimed responsibility for releasing it), and as long as the
+ same exception is not being propagated up (the next handler of the
+ propagating exception will then claim responsibility for releasing
+ it), so reraise no longer needs to clear the exception pointer, and it
+ can just propagate the exception, just like Reraise_Occurrence.
+
+ ABI #1 is fully interoperable with ABI #0, i.e., exception handlers
+ that call the #0 primitives can be linked together with ones that call
+ the #1 primitives, and they will not misbehave. When a #1 handler
+ claims responsibility for releasing an exception, even #0 reraises
+ dynamically nested within it will refrain from releasing it. However,
+ when a #0 handler is a handler of a foreign exception that would have
+ been responsible for releasing it with #1, a Reraise_Occurrence of
+ that foreign or other Machine_Occurrence-carrying exception may still
+ cause the exception to be released multiple times, and to be used
+ after it is first released, even if other handlers of the foreign
+ exception use #1.
+
+
+ for gcc/ada/ChangeLog
+
+ * libgnat/a-exexpr.adb (Begin_Handler_v1, End_Handler_v1): New.
+ (Claimed_Cleanup): New.
+ (Begin_Handler, End_Handler): Document.
+ * gcc-interface/trans.c (gigi): Switch to exception handler
+ ABI #1.
+ (Exception_Handler_to_gnu_gcc): Save the original cleanup
+ returned by begin handler, pass it to end handler, and use
+ EH_ELSE_EXPR to pass a propagating exception to end handler.
+ (gnat_to_gnu): Leave the exception pointer alone for reraise.
+ (add_cleanup): Handle EH_ELSE_EXPR, require it by itself.

++ -- entry of the nested handler, installed when entering the
++ -- enclosing handler, ensures the exception will not be
++ -- released by the nested handler, but rather by the enclosing
++ -- handler.
++ --
++ -- - Reraise_Occurrence/reraise escapes the running handler,
++ -- and we run as an exceptional cleanup for GCC_Exception. The
++ -- Saved_Cleanup was reinstalled, but since we're propagating
++ -- the same machine occurrence, we do not release it. Instead,
++ -- we transfer responsibility for releasing it to the eventual
++ -- handler of the propagating exception.
++ --
++ -- - An unrelated exception propagates through the running
++ -- handler. We restored GCC_Exception.Saved_Cleanup above.
++ -- Since we're propagating a different exception, we proceed to
++ -- release GCC_Exception, unless Saved_Cleanup was
++ -- Claimed_Cleanup, because then we know we're not in the
++ -- outermost handler for GCC_Exception.
++ --
++ -- - The handler completes normally, so it reinstalls the
++ -- Saved_Cleanup and runs it, unless it was Claimed_Cleanup.
