The reason for this change is that the strict parser made little sense
to exist. What would the recoder do if it was passed an invalid
string?
I believe that the tolerant recoder is more efficient than the
correcting code followed by the strict recoder. This makes the recoder
more complex and probably a little less efficient, but it's better in
the common case (tolerant that doesn't need fixes) and in the worst
case (needs fixes).

These functions are now aliases to {to,from}Ace, which are usually
what you want. The original functions from Qt 4.0 had the wrong

processing from IDNA (specifically, the ToASCII and ToUnicode
operations described in the RFC).
But so as not to be without tests, export the tests in unit testing

The used_mmap variable was set to true the first time an mmap operation
was successful, but it was never reset back to false. While that can be
a good indicator that future calls might succeed it is not a guarantee.
Not properly resetting could mean we'd unmap memory allocated with new,
instead of deleting it.
Since that variable is only used inside defined(QT_USE_MMAP) blocks, its
declaration is scoped the same way.
While mmap is still handled "by hand", use QFile for the other
operations. Calling mmap here is less than ideal, as it prevents use of
other memory mapping methods, such as native Windows APIs, but is less
intrusive as it allows QTranslator to retain control over lifetime of
the map. Using QFile for remaining operations reduces the number of
filesystem operations.
The file size is now checked to be minimally sane (<4GB), the limit of
the 32-bit variable that will hold mapping's length. Translation files
should be expected to be much smaller in practice, but there isn't a
sane hard-limit. The file format is broken down to sections, each of
which has a 32-bit length.
Finally, when loading a file fails, release resources immediately,
instead of delaying to next load attempt or the destructor.

There are only 8 MMX registers, each 64-bit wide, and they alias the
x87 registers. The access to the MMX register cannot use the new
VEX-prefix instructions either.
All of the functions being replaced are either present in the
qdrawhelper_sse2.cpp and qdrawhelper_ssse3.cpp files, or the plain C++
function in qdrawhelper.cpp is vectorised when compiled with
-ftree-vectorize (enabled in -O3), if SSE2 support is enabled.
All x86-64 processors have SSE2, so this is a net improvement for
64-bit builds. For 32-bit builds, without further support this will
cause the code to use non-vector or x87 instructions, which aren't the
best. The solution will come in another commit.

The reason to not save the key value pairs in qconfig.pri is
becase of the fact that the device spec loads the qdevice.pri
earlier than the qconfig.pri. qdevice.pri allows the mkspec
to set the compiler flags and qconfig.pri allows configure to

According to the Intel Optimization Manual section 3.5.1.1 Use of INC
and DEC Instructions, those instructions modify only part of the flags
register, so they mey introduce unnecessary data dependencies on
previous flag-setting operations so that the resulting flags are
computed. Preferring ADD and SUB (rule 33) is recommended.
However, we don't do it for 16-bit integers. The reason is that the
presence of the 0x66 prefix may trigger a slower decoding codepath in
the processor (up to 6 cycles, as opposed to 1). The same Intel manual
talks about Length-Changing Prefix, which applies in particular to
instructions with 16-bit immediates. The assembler generally produces
uses the 8-bit immediate variant of the ADD and SUB instructions, but
to be on the safe side, we prefer to use INC and DEC here.

The assembly output showed that GCC was generating some wrong code in
some conditions, so update the constraints so it will do the right
thing: the expectedValue constraint needs to be in/out with early
clobber. In/out because cmpxchg8b really does produce output and, even
if we don't care about it, GCC needs to be told that the registers
used (EAX:EDX) were modified. The early clobber is necessary so it
won't schedule EAX or EDX to be the same as the EBX_reg (the register
we'll xchg EBX with).
Since EAX and EDX are in/out and EBX can't be used, the only remaining
low register for the "sete" instruction is CL. So use it directly and
set ECX to be in/out too.
For whatever reason, it can't find enough registers in debug mode and
this expansion doesn't work. It looks like a bug though, since this
requires 4 registers and one memory operand and in debug mode it must
have EAX, ECX, EDX, ESI and EDI free for use. One of ESI or EDI is
used to xchg EBX with, which means there must be at least one more
free general register.
