On startup, PHP deliberately changes the floating point control word to
enforce binary64 format for the calculations for best consistency
across platforms. However, this is unnessary when compiling under
`__SSE__`, because in this case the x87 instructions are not used.
Therefore, we can skip the modification, which has the benefit that
system libraries are free to work in the mode of their liking.
The color resolution is expected in bits 4-6 of the packed fields byte
of the logical screen descriptor (byte 10 of the GIF data stream),
according to the specification[1], section 18.

We must not attempt to access arbitrary union members when retrieving
debug info, because that may not be valid. Therefore we do no longer
dereference pointer types inside of unions, but report their address as
string in `%p` format instead.
We map the POSIX semantics of `IPC_PRIVATE` by creating unnamed file
mapping objects on Windows. While that is not particularly useful for
ext/shmop, which is the only bundled extension which uses `shmget()`,
it may be useful for external extensions.
Partially reverts 846b647953: instead of
throwing, this skips uninitialized typed properties when serializing objects.
This makes serialize with __sleep() behave the same as serialize()
without __sleep().
As in the non-__sleep() case, unserialize(serialize($x)) identity
may not be preserved due to replacement of uninitialized/unset
properties with default values. Fixing this will require changes to
the serialization format.
Closes GH-5396.
When ArrayObject is round-tripped through serialize() and unserialize(),
it forgets any iterator class name which was set using ::setIteratorClass().
Fix that.
The `start` parameter of `php_cgi_ini_activate_user_config` is supposed
to hold the byte offset of the doc root in the given `path`. However,
the current expression which fixes a potential type incompatibility
will ever only evaluate to zero or one, because it uses the *logical*
and operator (`&&`). Furthermore we notice that subtracting one from
`doc_root_len` is not necessary, so there is even no need for the
`start` parameter at all.
I stumbled upon this while debugging a strange issue with
stream_socket_client() where it randomly throws out errors when
the connection timeout is set to below 1s. The logic to calculate
time difference in php_openssl_subtract_timeval() is wrong when
a.tv_usec < b.tv_usec, causing connection errors before the timeout
is reached.
The DO_INIT flag, which will skip the first resume on a primed
generator, should always be set when starting to yield from a
new generator, not only when the yield from happens during priming.
We actually implement `::__debugInfo()` and drop the `get_debug_info()`
handlers of all relevant SPL classes. This is cleaner and gives more
flexibility regarding overriding the functionality in descendant
classes.
