* | Add an automatic use of the ELF-versioned QtCore symbolThiago Macieira2015-10-203-1/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | See the comment in the header for an explanation of what it does. This trick is enabled for every single .o that is compiled, unless QT_NO_VERSION_TAGGING is defined. The assembly expands to a COMDAT section, which is mergeable by the linker, so only one copy of the output is present in the ELF module. This is enabled only for Linux and x86 / x86-64 / x32 due to the requirement of writing assembly and relocations, so it needs to be tested on each platform, which I have not done. It might work on Solaris/x86, but again it requires testing. Support for other architectures requires different assembly output and relocations and can be added as needed, but they are not as important since this trick is has most value on desktop systems.

* | Update qversiontagging.cpp not to use too much assembler magicThiago Macieira2015-10-202-57/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only reason I had used them in the first place was because C preprocessor macros cannot call themselves recursively. But the magic was too magic and caused issues with some builds, so let's choose the safer option. Anyway, this solution now works for all ELF architectures, independent of the processor, whereas previously it was restricted to x86 and Linux/ FreeBSD. However, this does not apply to the assembly in qversiontagging.h. Change-Id: I42e7ef1a481840699a8dffff1404f032fc5cacb8 Reviewed-by: Lars Knoll <lars.knoll@theqtcompany.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If QTimer::singleShot() is used with a functor callback and a context object with different thread affinity than the caller, a crash can occur. If the context object's thread is scheduled before connecting to QCoreApplication::aboutToQuit(), the timer has a change to fire and QSingleShotTimer::timerEvent() will delete the QSingleShotTimer object making the this pointer used in the connection invalid. This can occur relatively often if an interval of 0 is used. Making the moveToThread() call the last thing in the constructor ensures that the constructor gets to run to completion before the timer has a chance to fire.
