4e7f92bf0d QMetaType: Fix normalization on MSVC if name contains enum
During type normalization, we remove the struct, class and enum
keywords (see the skipStructClassOrEnum function). However, we only want
to do that for actual keywords, not for a name that happens to start
with e.g. "enum", as in "enumerationNameSpacce".
Adjust the MSVC check to still require no identifier character after the
keyword, while still allowing for some remaining characters.

20104bb237 Remove remnants of the old Intel C++ compiler
We don't support it any more. I don't think it has ever properly
compiled Qt 6 (and it's no longer working for me against GCC 12's
libstdc++ headers). If you report a bug against it, Intel support's
first question is if you can try instead the new Clang/LLVM-based oneAPI
C++ compiler.

So we support only that one, which identifies itself as Q_CC_CLANG.

ff0ee3d985 CMake: Handle strip wrapper creation more robustly
Unsetting CMAKE_STRIP and including CMakeFindBinUtils to find it again
is not safe, because CMakeFindBinUtils has logic to search for
additional tool names depending on the currently processed language.

The currently processed language is set in _CMAKE_PROCESSING_LANGUAGE
only when CMake is doing it's language introspection via
CMakeCXXCompiler.cmake.

This resulted in the build system finding a regular host-OS strip,
rather than an android specific llvm-strip when doing an Android
build, which then silently failed to strip the Android libraries
and caused us to ship big binaries.

Improve the strip wrapper creation in a few ways:
- Save the original strip value on first configuration
- Restore it if needed, without using CMakeFindBinUtils
- Don't apply the strip wrapper creation logic to Android,
  we currently don't need it there
- Add some informational messages about which CMAKE_STRIP
  ends up being used even if log-level is not DEBUG
- Fix a typo

d9be9fedfb Add a clear action to QKeySequenceEdit
This can be really helpful for deleting shortcuts that one may never
intend to use so that they do not accidentally get in the way while
interacting with the user interface.

The workaround is to try to find the QLineEdit child of the
QKeySequenceEdit widget, but it is suboptimal. Some first-class citizen
API for this would be a more stable and cleaner solution as opposed to
poking implementation details as a user of the QKeySequenceEdit API.

The clear action would be configurable and opt-in as not everyone may
potentially want this to be turned on. Or at least, not by default
anyway. Also, not to suddenly change existing QKeySequenceEdit uses with
surprising UI changes after a Qt upgrade, this needs to be opt-in.

Moreover, some customers may have already used findChild<QLineEdit *>()
to add actions to QKeySequenceEdit in this way on the client side. So,
if it was enabled by default, they would suddenly get multiple actions
potentially for the same clear action. This would be certainly
undesirable.

The new clear property is based on the corresponding QLineEdit API for
consistency.

[ChangeLog][QtWidgets][QKeySequenceEdit] Added a clear action to
QKeySequenceEdit to be able to remove existing hotkey configurations.

7f72622c0f QIOSTextResponder: recreate responder upon reset
Apple introduced UITextInteraction in iOS 13, which
caused issues with our text handling, and resulted in
e00d888dae. This, again, seems to be the reason why
UIKit in some cases simply removes the input delegate
from our text responder. This typically happens after
a QPlatformInputContext::reset(), and then when the
next character is typed on the input panel (and hence,
leaves no informative stack trace).

The result of removing the input delegate, which is the
interface that let's Qt communicate IM changes back to
UIKit, leads Qt and the UIKit out of IM sync. E.g for a
japanese keyboard, after a QPlatformInputContext::reset(),
the Qt input field would remove the marked text, but
UIKit would still show japanese characters
based on what used to be marked text.

To work around this issue, this patch will therefore
recreate the text responder when Qt tells us to reset.
This will cause the first responder to change, which will
apparently also reset the UIKit IM state.

2d3894f356 rhi: d3d: Fix not resetting the pipeline tracking between passes
Do what all other backends do. If we did not want to reset the pipeline
tracking pointer, then more logic would be needed, in order not to end
up in trouble with clients that do:

loop:
  create a pipeline // [1]
  beginpass
  ... // use the pipeline
  endpass
  readback
  finish
  destroy the pipeline
  goto loop

...because we may get the exact same pipeline pointer (with a matching
generation even since it's always 1 in this case) in the different
passes, just because malloc decided to do so in [1]. This could be
solved by checking the global resource id but won't do that now as no
other backends do it either.

This solves random broken rendering with the Qt Quick 3D lightmapper.
The above outline is exactly what the UV rasterization stage does.

877c158c59 Add ARM YIELD support to qYieldCpu()
YIELD is ARM's equivalent of x86's PAUSE, available since ARMv6k,
which should be old enough that we can use it unconditionally.

The ARM manual[1] defines the __yield() intrinsic for this, however:

- Clang has __builtin_arm_yield, the naming is compatible with what
  GCC would use, so we use that if available, to avoid having to
  include even more headers.

- GCC (incl. 12) doesn't have __yield() in arm_acle.h or anywhere
  else, and it doesn't seem to have the builtin (yet, one can always
  hope), so we use asm() there.

- Windows doesn't have an arm_acle.h header, but the docs[2] say it
  should have __yield(). Unfortunately, the docs don't say where
  the intrinsic is hiding, but we already include <intrin.h>, and
  godbolt[3] confirms that's sufficient to use __yield(). We could use
  YieldProcessor(), but we'd need to include qt_windows.h, I guess,
  which I'd rather not.

- Integrity doesn't have the arm_acle.h header, we use asm(), here, too.

fc16855eaa Fix qmake/qtpaths -query for static relocatable builds
The install prefix was determined incorrectly for static relocatable
builds.  The reason was that for those builds, QLibraryInfo::path()
returns the application directory, which is <prefix>/bin for qmake and
qtpaths.

Fix this by removing the bin directory part from the installation prefix
that QLibraryInfo returns if qmake/qtpaths are used.

277c23956c tst_qobjectrace: fix potential UB (something with pointers and new)
The current [basic.life] wording seems to cover the existing code, but
IIRC, older versions of [basic.life] were not so relaxed. In
particular, while not completely pertinent, the second placement new
is awfully similar to http://eel.is/c++draft/ptr.launder#example-1

Just make all of this SEP and use std::optional. That way, the code
gets simpler, too, plus we get rid of the last use of C++23-deprecated
std::aligned_storage.

The reset() before the 2nd emplace() isn't necessary, but, in a test,
it doesn't hurt, either, and keeps code readers from guessing whether
the first-emplaced object's dtor is actually properly run (it is).

38002df206 Endian: Provide special integer bitfield unions
Our previous approach of creating a union from individual special
integer bitfields leads to undefined values because only one member of a
union can be active at any given time. Compilers have finally caught up
with us on that and have started removing "no-op" writes to members.

The primary user of the special integer bitfield unions is
qv4compileddata_p.h in qtdeclarative. We want our on-disk format of
QML compilation units to be platform agnostic and space efficient.

dffba486d1 QXmlStreamReader: port Value::prefix from int to qint16
The prefix is a part of a name, the length of which is bounded to 4k
in fastScanName(), so qint16 suffices.

The length field also shouldn't stay int, but that's a different
patch, because it's just a relative offset to pos, and so isn't as
easily overflown.

This shrinks the Value struct a tiny bit; created QTBUG-103306 to
