| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QKeySequence::PortableText is the default value for argument passed to QKeySequence::toString(), and it doesn't need to be mentioned specifically in description for Qt::AA_MacDontSwapCtrlAndMeta enum value. Dropping the parameter shortens the text string, allows browser to better wrap the table text, and gets rid of the automatic horizontal scrollbar in online style. This improves readability for the entire table. Change-Id: I7051f5415a7a100b8c76f23b06b6cb9a2b0699ef Reviewed-by: Martin Smith <martin.smith@theqtcompany.com>

In its current state, it does the exact opposite of what it is supposed to be doing. 2) There is another environment access inside qsimd.cpp (which checks QT_NO_CPU_FEATURE). This access causes the app to hang. All in all that approach is not sustainable as we might get bitten by environment access again and again. Instead we should use another environment container or use a recursive mutex for WinRT and Windows CE.

EcmaScript explicitly prohibits leading zeroes in exponents. It is thus worthwhile to add those flags in order to be able to generate and parse doubles in compliance with EcmaScript. [ChangeLog][QtCore][QLocale] Additional flags in QLocale::NumberOption allow generating and parsing doubles in EcmaScript compliant format.

But no-one ever used this, because just passing QString::utf16() to QString::asprintf() creates a warning about wchar_t* expected, but ushort* provided. The new qUtf16Printable() macro adds the necessary casts (via void* to prevent any "type-punned pointer" warnings) to make passing QString::utf16() to QString::asprintf() work silently. This should greatly reduce the need to do a round-trip via utf-8 just to print the contents of a QString. [ChangeLog][QtCore] Added qUtf16Printable().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In C++, signed overflow math is Undefined Behavior. However, many CPUs do implement some way to check for overflow. Some compilers expose intrinsics to use this functionality. If the no intrinsic is exposed, overflow checking can be done by widening the result type and "manually" checking for overflow. Or, for X86, by using inline assembly to use the CPU features. Used in QtQml. Change-Id: I2ef2523ccaa98f6757a45e24862a2fa730a26bb0 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

Technically, the function doesn't have a wide contract, because it has the precondition that the buffer pointed to by the first argument needs to be large enough to hold the result. But that precondition can't be checked from within the function, so no failure can be generated for it and thus the nothrow guarantee is acceptable (and desireable).
