* Replace qrand() engine with C++11 <random> LCG and deprecateThiago Macieira2017-11-301-83/+59
| | | | | | | | | | | | | | | | Instead of trying to adapt to whatever the C library may have and using QThreadLocalStorage, let's use a simple linear congruential generator engine from <random>. We can't use a single instance because qsrand() is documented to work per thread. I thought of using QRandomEngine, but had to make the choice between growing the QtCore code size and growing the per-thread data size. Code is sharable and is actually smaller than the sizeof(QRandomEngine), which is over 2500 bytes. sizeof(std::minstd_rand) is just sizeof(uint_fast32_t).

* Mark some functions as coldMarc Mutz2017-11-303-3/+18
| | | | | | | | | | | | | | | | | | | | | | | | Add Q_DECL_COLD_FUNCTION (__attribute__((cold))) to tell the compiler that the following functions are not usually executed in normal programs: - qWarning/qCritical/qFatal - qTerminate - assertion failure - qBadAlloc The effect of the attribute is that 1. These functions get put into their own section, .text.unlikely, and will be optimized for size, not speed. 2. Conditions that lead to one of these functions are automatically marked as unlikely (something we have done manually in the past) 3. (anecdotal) the compiler is less likely to inline these functions Text size effect of this change over all of QtBase: ~27KiB text size saved, of which 11KiB in QtCore alone.

| | * Fix the build when AVX2 is enabled but __F16C__ isn't definedThiago Macieira2017-11-221-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If -mavx2 is used, __AVX2__ is defined, which enables the F16C code after commit 280e321e52fd4e86545f3f0d4bd4e047786a897e, but that was wrong since we aren't allowed to use the F16C intrinsics with either Clang or GCC (we can only do that with GCC 4.9 and Clang 4.8, and only with an __attribute__ decoration). With ICC and MSVC, we are allowed to use the intrinsics, but the #include was missing. [ChangeLog][QtCore] Fixed a compilation issue with qfloat16 if AVX2 support is enabled in the compiler. Since all processors that support AVX2 also support F16C, for GCC and Clang it is recommended to either add -mf16c to your build or to use the corresponding -march= switch.

Moreover, since std::mt19937 doesn't make it easy to provide the ideal size either, we can't actually write code that operates optimally given a quint32 range either -- we only provide it via std::seed_seq, which is inefficient. However, we can do it internally by passing QRandomGenerator to the std::mersenne_twister_engine constructor, as it's designed to work.

This also enables hardware accelerated conversion on x86, when 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) for all its sources, which means the file gets interpreted as C++ by g++, clang++ and icpc. Those compilers at least don't leak any symbols.

We deprecate this and add horizontalAdvance() instead, to avoid the confusion in the future. Note that there was an internal width() overload which was only there for the purpose of supporting the Qt::TextBypassShaping flag. This flag has already been replaced by public API, so no such overload is added. Instead, we deprecate the TextBypassShaping flag as well, which makes sense, since a replacement has been made. Also note that there was a consistency problem with QFontMetrics and QFontMetricsF, which are supposed to be interchangeable. The QFontMetrics::width() functions for strings took an optional int length argument, while the floating point version did not. This error is corrected in the advance() functions. [ChangeLog][QtGui][Text] Added QFontMetrics::horizontalAdvance() and QFontMetricsF::horizontalAdvance() to replace the confusingly named width() function. The latter has now been deprecated.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's make it happen even later: at the time of QtCore's unloading from memory. This prevents issues with something using QRandomGenerator after the global static destructor would have run.
