* Move pointer size detection entirely to qprocessordetection.hThiago Macieira2015-10-261-12/+0
| | | | | | | | | | | | | | | | This commit removes the legacy ptrsize check, which was deficient because it did not work for multiarch systems (when we supported fat OS X binaries) and did not work for bootstrap builds because the size might be different when cross-compiling. Instead, let's rely on the predefined preprocessor macros to detect correctly. As a nice side-effect, this fixes 64-bit Android builds cross-compiled from Windows.

* Add an automatic use of the ELF-versioned QtCore symbolThiago Macieira2015-10-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | 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.

* Add code to perform overflow-checking additions and multiplicationThiago Macieira2015-09-231-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most processors have carry flags which they set on addition overflow, so it's a good idea to access them whenever possible. Most of them also have widening multiply instructions that can be used to detect overflow of the non-widening version. Tested to compile on: Architecture Compiler x86 GCC 4.9, GCC 5*, Clang 3.6*, ICC 16 beta x86-64 GCC 4.9, GCC 5*, Clang 3.6*, ICC 16 beta x86-64 ILP32 GCC 4.9, GCC 5*, Clang 3.6* IA-64 LP64 GCC 4.8 ARMv7-A GCC 4.9, Clang 3.6* AArch64 Clang 3.6* MIPS GCC 4.9, Clang 3.6* MIPS64 GCC 4.9, Clang 3.6* PowerPC GCC 4.9, Clang 3.6* PowerPC 64 GCC 4.9, Clang 3.6* SPARC Clang 3.6* SPARCv9 Clang 3.6* [*] supports the intrinsics If the compiler does not offer a way to detect an overflow, we do it by hand. For unsigned additions, that's easy, since the C++ language specifies the behavior of the overflow. That's also the reason why this code is implemented only for unsigned integers. For the multiplication, if the compiler does not support widening multiplications, we do it with a division instead. This is necessary for GCC < 4.5 and compilers not compatible with GCC or MSVC.

So let's give people a grace period and enforce only for GCC >= 5. Clang is affected, but differently. The problem only happens with -flto -- that is, it happens when the linker detects that it's creating a final executable. Maybe -Wl,-pie would fix it.

Clang has the same functionality when compiling an executable with -flto. We need to let the compilers know that they cannot use copy relocations, so they need to use really position-independent code. Position independent code throughout is not really required. We just need the compilers to use position-independent access to symbols coming from the Qt libraries, but there's currently no other way of doing that.

[ChangeLog][Important Behavior Changes] Q_ASSERT will now expand the condition even in release mode when asserts are disabled, albeit in an unreachable code path.

On the negative side, because we won't get warnings for unused variables initialized outside the Q_ASSERT, non-inlineable calls will not be elminated by dead code elimination, so they will remain in release code without warnings. Because of the expanded code now in Q_ASSERT, the Intel compiler's optimizer gets thrown: it complains that the non-void function is failing to return anything, so I had to add two return statements.

* | Add qEnvironmentVariableIntValue()Marc Mutz2014-09-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot of code in Qt uses VAR=1 for enabling or disabling some feature or other, ignoring qEnvironmentVariableIsSet(), which was added for that purpose. Other code actually reads numerical values from environment variables. For both use-cases, provide a non-throwing, non-memory-allocating way to get the numerical (int) value of an environment variable, complementing qEnvironmentVariableIs{Set,Empty}(). [ChangeLog][QtCore] Added qEnvironmentVariableIntValue(). Change-Id: I81c85287ea10d355c1bbf8d7807ec9a0e477bce0 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | In C++98, typename can only be used for argument-dependent types and that's not the case here. This was tracked as language defect 382 and was fixed in the final C++11 standard, but the fix didn't make it to GCC 4.3 and 4.4 (which do have decltype). qthreadpool.cpp:274: error: using 'typename' outside of template Task-number: QTBUG-40783 Change-Id: I0eb702b33d2e8c95284f52841b0021dbfc743874 Reviewed-by: Olivier Goffart <ogoffart@woboq.com>

| * Fix annoying warning from ICC 14 on WindowsThiago Macieira2014-07-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It says that defining a macro that does defined() is not portable. The solution implemented for MSVC 2008 and earlier does work, however, and is portable to all compilers (the parentheses around the macro are unnecessary). Incidentally, this makes d98004cd2f33e8147cff9f3cb203fdef5e6dd00e actually work: Q_CC_MSVC wasn't defined at that point in the file, so that change had never taken effect. warning #3199: "defined" is always false in a macro expansion in Microsoft mode Task-number: QTBUG-39597 Change-Id: Iaa2895e7f63d97c439090043435a2b8d2f185c3a Reviewed-by: Oswald Buddenhagen <oswald.buddenhagen@digia.com>
