* Add initial clang-cl support to QtAndreas Holzammer2016-02-111-3/+3
| | | | | | | | | | | | | | | | | | | This adds the functionality to build Qt with clang under Windows against the Microsoft Visual Studio 2015 runtime. In order to replicate this, a Clang 3.8 build with Visual Studio 2015 Update 1 is needed. Adds compiler detection to Qt to distinguish correctly the clang compiler and Windows with Visual Studio. Clang has some built-in numeric functions, there is no need to use the Microsoft versions, which also conflict here.

* | Add {add,sub,mul}_overflow for signed integers.Erik Verbruggen2015-11-201-1/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | Qt already assumes a working IEEE-754 implementation, so we can rely on a working std::numeric_limits<double>.

* Add code to perform overflow-checking additions and multiplicationThiago Macieira2015-09-231-0/+117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Deprecate qMemCopy/qMemSet in favour of their stdlib equivilents.Robin Burchell2012-04-111-3/+3
| | | | | | | | | | | | | | | | | | Just like qMalloc/qRealloc/qFree, there is absolutely no reason to wrap these functions just to avoid an include, except to pay for it with worse runtime performance. On OS X, on byte sizes from 50 up to 1000, calling memset directly is 28-15% faster(!) than adding an additional call to qMemSet. The advantage on sizes above that is unmeasurable. For qMemCopy, the benefits are a little more modest: 16-7%.

* Remove ARMFPA support and Q_DOUBLE_FORMAT detectionBradley T. Hughes2012-03-011-42/+0
| | | | | | | | | | | | | | | | | Remove the -armfpa option the config.tests/unix/doubleformat* detection. The places where we used QT_ARMFPA and Q_DOUBLE_FORMAT has been removed as well. Rationale: ARM FPA with GCC does not work with EABI. Qt currently does not support compiling without EABI, making ARM FPA an impossibility. It is unknown whether other compilers provide ARM FPA support with EABI. Support for ARM FPA can be re-added in the future should the need arise, but since ARM VFP is available for ARMv5 and up, we should encourage implementors to instead use soft-floats or VFP.
