* Use the namespace-mangled symbol for the qt_version_tag group nameThiago Macieira2017-07-071-1/+1
| | | | | | | | | | Doesn't affect our current builds since it's just a marker for the linker on what sections should be merged. Unless you're mixing namespaced and non-namespaced static builds into one executable.

| * Fix build on Linux/x32 systems (x86-64 ILP32)Thiago Macieira2016-04-191-2/+2
| | | | | | | | | | | | | | | | | | | | When I tested this, it compiled, but either I wasn't using the same compiler or the problem happens during linking: we can't use .quad (64-bit) with a relocation on x32. So instead, let's use .long (32-bit). Task-number: QTBUG-52658 Change-Id: Ifea6e497f11a461db432ffff14468d1a16f49c67 Reviewed-by: Shawn Rutledge <shawn.rutledge@theqtcompany.com>

After the refactoring, 14960f52, in 5.7 branch and a merge, it is not needed any more.

| * Work around Clang < 3.7 integrated assembler bug PC-relative relocsThiago Macieira2016-02-021-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The qversiontagging.h inline assembly expands to: .long qt_version_tag@GOTPCREL Which, with GCC, Clang >= 3.7 and with the option -no-integrated-as in previous versions, produces the proper relocation (a R_X86_64_GOTPCREL). With Clang < 3.7, it instead produces a R_X86_64_32, which is unsuitable for use in shared libraries: 32-bit displacement is insufficiently wide and would produce linker errors like obj/qftp.o: requires dynamic R_X86_64_32 reloc against 'qt_version_tag' which may overflow at runtime; recompile with -fPIC Instead, force a 64-bit relocation (an R_X86_64_GOT64), which like the 32-bit version is simply an offset into the GOT of where the address of the symbol is stored.

| * Fix the use of R_X86_64_GOTPCREL on a 64-bit field: it should be 32-bitThiago Macieira2016-01-211-5/+7
| | | | | | | | | | | | | | | | | | | | | | The ABI says that PC-relative displacements should be on 32-bit fields, even on 64-bit builds. For -mcmodel=large, it should use R_X86_64_GOT64 relocations, like 32-bit.

* Workaround part 2: don't use the version tagging symbols on AndroidThiago Macieira2015-11-041-1/+1
| | | | | | | | | | | | | | Commit d020e0781cf8647d87f7088350e40adf4f0cf8fe added a workaround to the QtCore build due to a qmake bug in handling the extra target on a Windows host. The workaround removed the tagging symbols from QtCore. This commit removes the using of those symbols from everywhere else.

* Add an automatic use of the ELF-versioned QtCore symbolThiago Macieira2015-10-201-0/+86
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.
