* Add Intel copyright to files that Intel has had non-trivial contributionThiago Macieira2016-01-211-0/+1
| | | | | | | | | I wrote a script to help find the files, but I reviewed the contributions manually to be sure I wasn't claiming copyright for search & replace, adding Q_DECL_NOTHROW or adding "We mean it" headers.

* Add {add,sub,mul}_overflow for signed integers.Erik Verbruggen2015-11-201-0/+31
| | | | | | | | | | | | | | 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>
* Implement qt_is_{inf,nan,finite} using std. library functions.Erik Verbruggen2015-10-301-0/+12
| | | | | | | | | | | | The previous implementations did not check the full mantissa. The result was that certain NaN values were seen as +/-Infinity. A nice benefit is that the generated code for this implementation is also faster.

| * Add code to perform overflow-checking additions and multiplicationThiago Macieira2015-09-232-1/+161
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
