Subject: [PATCH] Add a facility to version type information for debugging
This serves the same purpose as qtbase/corelib/global/qhooks.cpp,
but is meant to be in sync with changes in Qt Declarative internals.

From aa7c3b35ef9b737c574f436ea35452019a2ff29c Mon Sep 17 00:00:00 2001
From: Erik Verbruggen <erik.verbruggen@digia.com>

Subject: [PATCH 1/1] V4: Always set the tag when boxing a pointer in
QV4::Value.
All setters now store tags, so no-one can play loosy-goosy with the
boxed values (and accidentally forget to "tag" a value, resulting in
random garbage).

We use two different ways of encoding JS values. One for 32bit and one for 64bit systems.
- In both cases, we use 8 bytes for a value and a different variant of NaN boxing. A Double NaN (actually -qNaN)
- is indicated by a number that has the top 13 bits set. The other values are usually set to 0 by the
- processor, and are thus free for us to store other data. We keep pointers in there for managed objects,
- and encode the other types using the free space given to use by the unused bits for NaN values. This also
- works for pointers on 64 bit systems, as they all currently only have 48 bits of addressable memory.
-
- On 32bit, we store doubles as doubles. All other values, have the high 32bits set to a value that
- will make the number a NaN. The Masks below are used for encoding the other types.
-
- On 64 bit, we xor Doubles with (0xffff8000 << 32). That has the effect that no doubles will get encoded
- with the 13 highest bits all 0. We are now using special values for bits 14-17 to encode our values. These
- can be used, as the highest valid pointer on a 64 bit system is 2^48-1.
-
- If they are all 0, we have a pointer to a Managed object. If bit 14 is set we have an integer.
- This makes testing for pointers and numbers very fast (we have a number if any of the highest 14 bits is set).
-
- Bit 15-17 is then used to encode other immediates.
+ In both cases, we use 8 bytes for a value and a different variant of NaN boxing. A Double
+ NaN (actually -qNaN) is indicated by a number that has the top 13 bits set, and for a
+ signalling NaN it is the top 14 bits. The other values are usually set to 0 by the
+ processor, and are thus free for us to store other data. We keep pointers in there for
+ managed objects, and encode the other types using the free space given to use by the unused
+ bits for NaN values. This also works for pointers on 64 bit systems, as they all currently
+ only have 48 bits of addressable memory. (Note: we do leave the lower 49 bits available for
+ pointers.)
+
+ On 32bit, we store doubles as doubles. All other values, have the high 32bits set to a value
+ that will make the number a NaN. The Masks below are used for encoding the other types.
+
+ On 64 bit, we xor Doubles with (0xffff8000 << 32). That has the effect that no doubles will
+ get encoded with bits 63-49 all set to 0. We then use bit 48 to distinguish between
+ managed/undefined (0), or Null/Int/Bool/Empty (1). So, storing a 49 bit pointer will leave
+ the top 15 bits 0, which is exactly the 'natural' representation of pointers. If bit 49 is
+ set, bit 48 indicates Empty (0) or integer-convertible (1). Then the 3 bit below that are
+ used to encode Null/Int/Bool.
+
+ On both 32bit and 64bit, Undefined is encoded as a managed pointer with value 0. This is
+ the same as a nullptr.

From 5149aa68eca6ede8836ec4f07a14d22d9da9b161 Mon Sep 17 00:00:00 2001
From: Mitch Curtis <mitch.curtis@qt.io>
Date: Tue, 13 Sep 2016 12:42:12 +0200
Subject: [PATCH 1/1] Fix crash on exit when using default property aliases
with layouts
The layout was being destroyed before the text, which meant that the
removeItemChangeListener() call never got hit. To ensure that the
listener is always removed, loop through each child in QQuickLayout's
destructor.
This is a manual cherry-pick of
59c6c0e0b1b5b46747595a58e11311b7393d7e70.

Subject: [PATCH] V4: Align stack on 16 byte boundaries in the YarrJIT
This is the required alignment for Aarch64, and a number of other ABIs
prefer this size too when calling into system libraries.
