... as it has outlived its original purpose:
Qt3 implementation on X11:
void QApplication::flush() { flushX(); }
void QApplication::flushX() { if (appDpy) XFlush( appDpy ); }
Qt4 implementation on X11:
Did nothing when QApplication::flush() was called (the flush()
overrides in {unix,glib} event dispatchers with empty bodies).
In Qt5 this function somehow has been repurposed (inconsistently)
to do what QCoreApplication::sendPostedEvents already does:
QAbstractEventDispatcher::flush() = 0;
=> QCocoaEventDispatcher::flush() {}
=> QEventDispatcherCoreFoundation::flush() {}
=> QIOSEventDispatcher (does not override ::flush())
=> QEventDispatcherGlib::flush() {}
=> QPAEventDispatcherGlib (does not override ::flush())
=> QEventDispatcherUNIX::flush() {}
=> QUnixEventDispatcherQPA (when QT_NO_GLIB=true)
::flush() { if (qApp) qApp->sendPostedEvents(); })
==> QAndroidEventDispatcher (does not override ::flush())

}
=> QWinRTEventDispatcher (qminimaleglintegration.cpp) (does not override ::flush())
=> QWinRTEventDispatcher (qwinrteventdispatcher.h) (does not override ::flush())
Whatever this function was doing on macOS in Qt3 and Qt4 also has been
dropped in Qt5. It appears that the other event dispatchers in Qt5 that
have overrides for flush() have simply copy-pasted this logic.
Clearly the documentation of QCoreApplication::flush() is outdated and
has nothing to do with the actual implementation in Qt5.
This function is rarely used in Qt5 sources. It should be safe to remove
the calls to QCoreApplication::flush() from Qt source code, as this
function has been doing nothing on most platforms anyways. Repurposing
it even broke handling of posted events (see QTBUG-48717).

It only contained a concatenation of the individual rule sets,
probably to fix their order in a central place, as well as
simplifying iteration in defaultCategoryFilter().
Fix these two issues differently, but introducing a RuleSet
enum that lists rule sets in the order in which they should
be applied by defaultCategoryFilter(), and turn individual
rule sets vectors into a C array of vectors.
This enables two nested loops in defaultCategoryFilter to
replace the one loop over 'rules'. Apart from building up
'rules' in updateRules(), this was the only access to that
member. That leaves updateRules() with just the task of
running defaultCategoryFilter() on the new rule sets.
Consequently, a call to updateRules() can now replace the
identical loop in installFilter().
Performance should not suffer. Iterating over a fixed-size
array of vectors is hardly any slower than iterating over
a single vector, and while the construction of 'rules'
was probably a one-off task in most programs, this way
of keeping the rules also saves memory because rules are
not kept in two different vectors.
It is also more maintainable, of course.

Factor the line parsing into a separate function, parseNextLine(),
taking a QStringRef.
In setContent(QTextStream&), use the new readLineInto() function to
re-use the capacity of a single QString for all lines.
In setContent(QString), use splitRef() to split the lines.
In either function, pass each line to parseNextLine().
In order to port all the parsing to QStringRef, I needed to make some
semantic changes: the old code removed all whitespace right at the
beginning. This is not possible with QStringRef. It also didn't feel
right, since a line like
[ r u l e s ]
would successfully parse as the section named "rules".
I added trimmed() calls at the beginning, and around the valueStr and
pattern extraction, which should be good enough.
Also, when a section is found, don't store it anymore. Instead, only
store whether it was the [rules] section, because that's all we'll
test for. That way, we don't have to convert QStringRefs to QString
just to store them across parseNextLine() calls.
Replace the setSection() function with setImplicitRulesSection(),
because "rules" is all that was ever passed.
This is private API, we can bring back some of the dropped flexibility
later, as needed.

Neither the Intel compiler nor Visual C++ have a dedicated switch to

for that in commit 8241d51f70, as it was
the closest, lowest denominator. That was incorrect and insufficient.
The Intel compiler silently miscompiles the intrinsics with -xAVX,
making calls to out-of-line functions like _mm_cvtps_ph, which don't
exist. So we actually have to use AVX2 support to generate correct code.
That might be a problem later, since Ivy Bridge supports F16C but not
AVX2.
Visual C++ is able to generate F16C code with just -arch:AVX.
Either way, since there's no dedicated command-line switch, there's also
no dedicated preprocessor macro. We're using __AVX2__ for both
compilers, as that's a sufficient condition to indicate a processor that
supports F16C.

Fix the condition in QWidgetPrivate::resolveLocale() to decide whether
to propagate locale: make it match setLocale_helper()'s condition when
deciding whether to propagate to descendants. This lead to a
QDateTimeEdit's calendar popup not getting told what locale to use
correctly, unless we setLocale() on it overtly, which then blocked
propagation of locale changes to it unless QDateTimeEdit manually
propagated the changes.
Fix the documentation of WA_WindowPropagation to mention locale as
also being propagated (which it was in several places, only neglecting
this one in resolveLocale).
[ChangeLog][QWidget][Qt::WA_WindowPropagation] Propagate locale
consistently, along with font and palette, within the widget
hierarchy. Previously, locale was propagated on ancestral
setLocale(), but not on creation of the descendant.

Commit e0ea0f6178 optimized QChar <->
QString(Ref) comparisons by adding more overloads to avoid creating
QStrings from QChars just to compare them.
But these new overloads made existing comparisons to QChar ambiguous.
This was known at the time for QChar/int comparisons.
It has since turned out that also comparing to '\0' is ambiguous,
ie. not comparing to int or char per se is ambiguous, but comparing to
nullptr constants is, because QString(const char*) is just as good a
candidate as QChar(char)/QChar(int).
Since we allow QString/QChar comparisons, it seems logical to solve
the problem by adding QChar<->nullptr overloads.
[ChangeLog][QtCore][QChar] Disambiguated comparisons with nullptr
constants such as '\0', which 5.8.0 broke. As a consequence,
QChar<->int comparisons are no longer deprecated, as this was a failed
attempt at fixing the ambiguity.

Timer IDs have been reused since Qt 4.5 or thereabouts, so just checking
if the timer ID is in the timer dictionary is an incorrect check: our
timer may have been deleted and replaced by another with the same ID.
Instead of deleting the WinTimerInfo object, let's just mark it as
unregistered by setting timerId to -1 and cooperate in deleting at the
appropriate places. Since unregisterTimer skips deleting if inTimerEvent
is true, the appropriate places are everywhere that set inTimerEvent to
true.

It's a Qt 3 compatibility vehicle, and as such inherits the now-alien
property to distinguish empty and null strings. Particularly worrisome
is the following asymmetry:
QString("") == QString::null // false
QString("") == QString(QString::null) // true

a weird way to call isNull(), albeit one that once was idiomatic, and
simply deprecate everything that deals with QString::null.

Commit fb376e0fcc removed an array that
facilitated returning the names of built-in types, to avoid the jump tables
from the switch statement. This commit brings it back but makes the array a
compile-time constant string offset table.
The array is created by way of a set of C++11 constexpr functions, so we
require that compiler feature. I've tested that MSVC 2015 does support
it as well as the ICC 17 when masquerading as MSVC 2015, so I've enabled
for that too. The only compiler left out is MSVC 2013.
If we didn't need to support MSVC 2015, this could have been written
more simply with C++14 relaxed constexpr.
This also adds unit tests to confirm that QMetaType::typeName() does
return null when we said it would. We're testing QMetaType::User-1
(which we'll likely never use) and QMetaType::LastWidgetsType-1 to
select something inside the range of the built-in types.
