* Optimize QString::compare_helper(QChar*, int, char*, int, cs)Marc Mutz2016-08-041-3/+9
| | | | | | | | | | | | | | | | | | | | ... by using the recently-added QUtf8::convertToUnicode() and a QVarLengthArray instead of QString::fromUtf8(). Like elsewhere in QString, use a QVarLengthArray<ushort> instead of the more natural <QChar> to avoid instantiating another QVLA. Assume that length2 is usually set to a non-negative value. Not because that's necessarily the frequent case, but because a negative length2 leads to an expensive strlen, that usually dwarfs the additional branch cost. Check for data2 == nullptr early to avoid having to check it later twice. Change-Id: I04bda44ed857451efdf04c3283b5726480dd8c0d Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

| | * QString::replace(): protect sought text and replacementEdward Welbourne2016-07-121-20/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When replacing each copy of one text with a copy of another, we do so in batches of 1024; if we get more than one batch, we need to keep a copy of the sought text and replacement if they're part of the string we're modifying, for use in later batches. Also do the replacements in full batches of 1024, not 1023 (which left the last entry in an array unused); marked some related tests as (un)likely; and move some repeated code out into a pair of little local functions to save duplcation. Those new functions can also serve replace_helper(); and it can shed a const_cast and some conditioning of free() by using them the same way replace() now does. (There was also one place it still used the raw after, rather than the replacement copy; which could have produced errors if memcpy were to exercise its right to assume no overlap in arrays. This error is what prompted me to notice all of the above.) Added tests. The last error proved untestable as my memcpy is in fact as fussy as memmove. The first two tests added were attempts to get a failure out of it. The third did get a failure, but also tripped over the problem in replace() itself. Added to an existing test function and renamed it to generally cover extra tests for replace.

Wrap this trick in template functions in qsimd_p.h. These are marked as always- inline and use __builtin_memcpy() where available in an attempt to avoid the memcpy() function call overhead in debug builds. While this looks prohibitively expensive, from the pov of the C++ abstract machine, it is 100% equivalent, except for the absence of undefined behavior. In one case, the cast produces a local temporary which is then copied into the function, and in the other case, that local variable comes from return value of qUnalignedLoad(). Consequently, GCC compiles these two versions into identical assembler code (only verfied for ucstrncmp, but there's no reason to believe that it wouldn't hold for the other cases, too).

The QUtf8 overload allocates no memory, and is therefore marked as nothrow. Using this function in convertFromAscii() allows to mark this function nothrow, too. All functions of QAbstractConcatenable can now be marked as nothrow. Since QUtf8::convertToUnicode() does not deal with lengths of -1, insert a strlen() call when the len == -1 ASCII fast path fails due to non-ASCII chars. Saves 1.1KiB in text size on optimized GCC 5.3 Linux AMD64 builds of QtCore (other libraries are compiled without exceptions, so this change should not have an effect on those).
