* QDateTimePrivate: inherit QSharedData and other cleanupsMarc Mutz2019-08-071-13/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't manage the ref-count yourself, as this requires the code to use the QAtomic copy ctor, which we want to remove going forward. Using QSharedData, we can let the compiler write the code for us. Since 'ref' this way moves to the first spot in the list of effective members, creating a 4B hole between itself and 'msecs', swap 'status' and 'msecs' to fill the hole: offset: 0 8 16 24 | | | | without v v v v adj.mnt: |*R*| | msecs | S | U | TZ.... before: | msecs | S | U |*R*| | TZ... after: |*R*| S | msecs | U | | TZ.... This keeps the padding out of the critical first word, which improves latency. That said, for accessing the members the old layout surely was optimal. This layout optimizes copies and pessimizes access to 'msecs' on 32-bit platforms without the Critical Word First optimization. Requires adjustments to tst_toolsupport and the qhooks version. Also default members using NSDMI, consequently drop the manual default ctor.

* Simplify QDate::weekNumber() by looking at the right day of the weekEdward Welbourne2019-08-071-27/+14
| | | | | | | | | The Thursday in the same week has the same week-number and determines the right year to use for the week. So calculate its week-number and save a whole lot of complications. Change-Id: I9c28267e6083afdd04a15245e1609c64beb82b37 Reviewed-by: Lars Knoll <lars.knoll@qt.io>

* Move YearRange to QDateTime from its PrivateEdward Welbourne2019-07-014-9/+27
| | | | | | | | | | | | | | | | | As planned when adding YearRange: now that it's merged up to dev, move it to QDateTime, since we can add to the API at 5.14.0.

* Port from QAtomic::load() to loadRelaxed()Giuseppe D'Angelo2019-06-201-3/+3
| | | | | | | | | | | | | | | Semi-automated, just needed ~20 manual fixes: $ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)load\(\)/$1loadRelaxed\(\)/g' -i \{\} + $ find \( -iname \*.cpp -or -iname \*.h \) -exec perl -pe 's/(\.|->)store\(/$1storeRelaxed\(/g' -i \{\} + It can be easily improved (e.g. for store check that there are no commas after the opening parens). The most common offender is QLibrary::load, and some code using std::atomic directly. Change-Id: I07c38a3c8ed32c924ef4999e85c7e45cf48f0f6c Reviewed-by: Marc Mutz <marc.mutz@kdab.com>

* Rearrange date parsing in anticipation of calendar workEdward Welbourne2019-06-071-34/+29
| | | | | | | | | | | | | The calendar APIs shall need fromShortMonthName() to know its year number; so rearrange the date parsing that uses it to ensure the year number is known in time. In the process, pass &ok to toInt() also for the calls that get a day number (where failure's 0 return is an adequate check for failed parse), just to be on the safe side.
