392294936e qfloat16: suppress warning caused by Clang macro we used
Clang implements the _cvtss_sh intrinsic by way of a macro, which
uses a C99 extension and that's not allowed in C++ mode:

 float16.h:119:11: error: compound literals are a C99-specific feature [-Werror,-Wc99-extensions]
 /usr/bin/../lib64/clang/3.9.1/include/f16cintrin.h:76:55: note: expanded from macro '_cvtss_sh'

Reported at https://bugs.llvm.org/show_bug.cgi?id=32491.

8241d51f70 x86: Detect F16C with the Intel compiler too
The .pro file requires the QMAKE_CFLAGS_F16C to be set to something. So
set it to AVX, as the instructions require the VEX prefix anyway (ICC
has no dedicated option for just F16C).

a03390a8b0 Detect the (stated) C++ standard edition at build time
The configure-time detection (cxx11default) isn't enough if the compiler
can be changed. This is especially necessary if Qt is compiled with a
compiler that defaults to >= C++11 (e.g., GCC 6) and then the user
selects a compiler another compiler (e.g., Clang) via -spec option. In
that case, we'd miss adding the -std=c++11 or -std=gnu++11 option to the
command-line, causing the compilation to fail.

As a nice side-effect, even moc without moc_predefs.h will now get the
__cplusplus setting.

62013d7772 Mark to remove const from function parameters in QtCore public headers
Some compilers are known to complain about this with a warning. GCC
complains about const on return values on -Wignored-qualifiers (enabled
at -Wextra), so it's not too much of a jump to assume that others do
too. Besides, this is not Qt Library API policy. As maintainer for
QtCore, I'm exercising my prerrogative in specifying certain unspecified
parts of the coding style, like I've done for constructor initializer
lists.

Since all the classes involved are exported (including QVector, through
derived classes), we can't remove the qualifier until Qt 6, since there
are compilers known to encode the qualifier in the mangled name
(suncc). I'm not introducing #ifdef to silence unknown compilers unless
we get an actual complaint.

Implicit conversion from QByteArray to const char* works for most gtk

88a8feeacb QCryptographicHash: make SHA3 calculate SHA3, not Keccak
The SHA3 family is a modified version of Keccak. We were
incorrectly calculating Keccak (and even *testing* Keccak!),
but claiming it was SHA3.

To actually calculate SHA3, we need invoke Keccak on the original
message followed by the two bits sequence 0b01, cf. §6.1 [1].

[1] http://dx.doi.org/10.6028/NIST.FIPS.202

[ChangeLog][QtCore][QCryptographicHash] QCryptographicHash now
properly calculates SHA3 message digests. Before, when asked
to calculate a SHA3 digest, it calculated a Keccak digest instead.

9a0d47bcf1 tst_largefile: fix the mapOffsetOverflow case to match actual behavior
Unix mmap(2) system calls do allow for mapping beyond the end of the
file, though what happens after you try to dereference the pointers it
gives is unspecified. POSIX[1] says that implementations shouldn't allow
it:
 The system shall always zero-fill any partial page at the end of an
 object. Further, the system shall never write out any modified portions
 of the last page of an object which are beyond its end. References
 within the address range starting at pa and continuing for len bytes to
 whole pages following the end of an object shall result in delivery of
 a SIGBUS signal.

However, Linux allows this in read-write mode and extends the file
(depending on the filesystem).

Windows MapViewOfFile never allows mapping beyond the end.

22a414ab3d macOS: Remove workaround for default-sized NSViews
The workaround introduced in 38a55c7 to explicitly call viewDidChangeFrame()
was not ideal for a multitude of reasons. Instead we can just initialize the
NSView with a NSZeroRect frame, which will ensure that whatever geometry
we set from the Qt side will result in geometry change and expose events.

The only case where we will not receive an expose event is if the QWindow
is requested to be 0x0 sized, but that wouldn't warrant an expose event
anyways. Also, it's not possible to initialize a QWindow to 0x0 from the
Qt side, as that will trigger QPlatformWindow::initialGeometry() to pick
the default size (160x160 in the case of macOS).

There is nothing broken with not supporting BGRA for glReadPixels even when
GL_EXT_read_format_bgra (an out of date, pre-2.0 extension that got folded
into the spec to begin with) is present. We do not have a good way to tell
if BGRA_EXT is supported for glReadPixels or not, so just skip the whole

81b5aa792f QCocoaWindow - fix a compilation error
Clang does not like Q_FALLTHROUGH in 'default' label, the diagnostics is:
'fallthrough annotation does not directly precede switch label'.
Accodring to their docs: "The fallthrough (or clang::fallthrough) attribute
is used to annotate intentional fall-through between switch labels. It can
only be applied to a null statement placed at a point of execution between
any statement and the next switch label." - obviously, there is no 'next
switch label' in our case.
