Both ARM and x86 can convert fp16 much faster in bulk than one at a

F16C isn't unconditionally available at compile time.
This code is implemented in C to ensure that there's no leakage of
inline symbols from the .obj file that was compiled by Visual Studio
with AVX support. Unfortunately, simd.prf uses $(CXX) instead of $(CC)

g++, clang++ and icpc. Those compilers at least don't leak any symbols.

When parsing a date-time's zone, a stray Z denotes UTC (a.k.a. Zulu
time), despite not being a valid name for the zone. Clients parsing
such date strings had to treat the Z as a literal, rather than a
zone-ID, but then they got back a LocalTime instead of the UTC the
string actually described. So teach QTimeZoneParser to handle this
special case and adapt an existing test (that used a time ending in Z,
but had to treat it as a local time) to check this works.

The previous version was good, just not optimal. Because the input was
an unsigned 64-bit number, compilers needed to generate extra code to
deal with HW instructions that only convert 64-bit signed input. And
that was useless because a double uniformly distributed from 0 to 1 can
only have 53 bits of randomness.
The previous implementation did exactly what the Microsoft libstdc++ and
libc++ implementations do. In my opinion, those implementations have an
imperfect distribution, which is corrected in this commit. In those, all
random input bigger than 0x20000000000000 has a different frequency
compared to input below that mark. For example, both 0x20000000000000
and 0x20000000000001 produce the same result (4.8828125e-4).
What's more, for the libc++ and MSVC implementations, input between
0xfffffffffffff001 and 0xffffffffffffffff results in 1.0 (probability 1
in 2⁵³), even though the Standard is very clear that the result should
be strictly less than 1. GCC 7's libstdc++ doesn't have this issue,
whereas the versions before would enter an infinite loop.

Instead of modifying the path that the user provides, go straight ahead

this expansion impossible:
relative-part = "//" authority path-abempty

/ path-empty
path-abempty = *( "/" segment )
path-absolute = "/" [ segment-nz *( "/" segment ) ]
path-noscheme = segment-nz-nc *( "/" segment )
The "path-abempty" and "path-noscheme" cases are the two issues we
already handle. This commit adds the third one: path-absolute, which
requires that the first segment of the path be of non-zero length.
That is, it is now possible again to have http://example.com//path
constructed piece-wise, without it producing http://example.com/path.
Additionally, it catches the case of http://example.com//path parsed

That means a file is never created, unless you ask for the name. There's
no chance of left-over temporary files being left behind. QSaveFile also
benefits from this, since the save file is not present on disk until
commit(). Unfortunately, QSaveFile must go through a temporary name
because linkat(2) cannot overwrite -- we need rename(2) for that (for
now).
[ChangeLog][Important Behavior Changes][QTemporaryFile] On Linux,
QTemporaryFile will attempt to create unnamed temporary files. If that
succeeds, open() will return true but exists() will be false. If you
call fileName() or any function that calls it, QTemporaryFile will give
the file a name, so most applications will not see a difference.

This test sets up two timers:
- a 100ms recurring timer
- a series of 10 200ms single-shot timers.
After quitLock lets exec() return it then uses a signal
spy to check if the 100ms timer fired at least 17/20
of the times it should.
However there is no guarantee that the 100ms timer
will fire more often than the 200ms timer. If the
native timer callbacks happen at 500ms intervals then
Qt will fire both timers (once) at that interval.
In practice this seems to happen on macOS CI under
system load and/or with the test app napping.
The primary goal for the test is to verify that exec()
returns when it should; we can remove the timer signal
spy.
Remove testQuitLock from BLACKLIST.

On BSD systems (tested on macOS and FreeBSD), you *can* lseek(2) or

the position when the file is sequential, so we need to return 0.
Technically speaking, we ought to do the same for block devices, but if
you're redirecting stdin, stdout or stderr in the unit test to or from a
block device, you deserve the extra work to add that yourself to the

different; and it's possible to at least confirm the plausibility of
2-or-3 am on a spring or autumn day at a plausible transition (or even
to confirm it exactly by consulting suitable web-sites). Also
document the actual transition happening in each case (since I *did*
consult a suitable web-site). So prefer to QCOMPARE(,) two QDateTime
values instead of two 12-digit qint64s.
Where a that would be unsuitable, at least compare the difference to
zero, to make the error easier to understand (except when one of the

The getentropy function, first found in OpenBSD, is present in glibc
since version 2.25 and Bionic since Android 6.0 and NDK r11. It uses the
Linux 3.17 getrandom system call. Unlike glibc's getrandom() wrapper,
the glibc implementation of getentropy() function is not a POSIX thread
cancellation point, so we prefer to use that even though we have to
break the reading into 256-byte blocks.
The big advantage is that these functions work even in the absence of a
/dev/urandom device node, in addition to a few cycles shaved off by not
having to open a file descriptor and close it at exit. What's more, the
glibc implementation blocks until entropy is available on early boot, so
we don't have to worry about a failure mode. The Bionic implementation
will fall back by itself to /dev/urandom and, failing that, gathering
entropy from elsewhere in the system in a way it cannot fail either.
uClibc has a wrapper to getrandom(2) but no getentropy(3). MUSL has
neither.

the only ill effect is slightly slower lookups.
Concerning the environment block passed to Win32 CreateProcess:

case-insensitively and without regard to locale. See

First and most importantly, let's not use more than half of the template
for the application's PID. With over 71% of all PIDs on a typical Linux

using them all in a template that is usually 6 characters long is
wasteful. That leaves only 1 character for the random part, thereby
reducing the number of temporary files possible to only 52. So limit the
PID to half the characters of the template.
Second, let's use QRandomGenerator::bounded to create the the random

operator() like std::random_device, but unlike that, it also provides a
way to fill a buffer with random data, not just one 32-bit quantity.
It's also stateless.
Finally, it also implements std::seed_seq-like generate(). It obeys the
standard requirement of the range (32-bit) but not that of the algorithm
(if you wanted that, you'd use std::seed_seq itself). Instead,
generate() fills with pure random data.

QTimeZone("UTC") should be valid, as "UTC" appears in the list of
availableTimeZoneIds(), and tst_QTimeZone::dataStreamTest() constructs
timezones like this, which are considered valid.
The internal representation of a QTimeZone("UTC") as created by
QTimeZone::QTimeZone(const QByteArray &ianaId) is a QUtcTimeZonePrivate
which isValid(), so the containing QTimeZone isValid() too.
When QTimeZone is serialized into a QDataStream, it calls
tz.d->serialize(ds) which is QUtcTimeZonePrivate::serialize. This
writes QStringLiteral("OffsetFromUtc") followed by the IANA ID and
the offset (etc.) to the datastream.
When QTimeZone is deserialized it looks for this marker string, and if
present, it passed all of the parameters to the QTimeZone constructor
(not just the name). However, that constructor does not support standard
IANA timezones (only custom ones), and when it detects that the supplied
IANA ID is actually listed in availableTimeZoneIds(), it leaves the
pointer to the QTimeZonePrivate uninitialized (NULL), which leaves
the QTimeZone invalid (isValid() returns false).
Thus, a valid timezone which was serialized and then deserialized has
become invalid. This also affects serialization of QDateTimes with
timezones.
Fixed by calling the name-only constructor first, which works (only) for
IANA standard timezones and leaves the QTimeZone invalid (isValid()
returns false) otherwise. In which case, we can call the many-argument
contructor to create a custom timezone with the same offset as the one
which was originally serialized.
