* Rename qt_saturate to q26::saturate_castGiuseppe D'Angelo2024-08-181-35/+0
|||||||||||| C++26 adds std::saturate_cast, so follow the established pattern of other similar "backported" APIs. The old name is left around while we port other submodules. While at it, move qt_saturate's tests to the qnumeric test. Pick-to: 6.8 Change-Id: I653a2e3d936081378298a9c8e51e7c1a2d438d83 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

* Port Q_STATIC_ASSERT(_X) to static_assertGiuseppe D'Angelo2020-06-191-2/+2
||||||||||||||||| There is no reason for keep using our macro now that we have C++17. The macro itself is left in for the moment being, as well as its detection logic, because it's needed for C code (not everything supports C11 yet). A few more cleanups will arrive in the next few patches. Note that this is a mere search/replace; some places were using double braces to work around the presence of commas in a macro, no attempt has been done to fix those. tst_qglobal had just some minor changes to keep testing the macro.

* Featurize support for signaling NaNEdward Welbourne2019-09-301-0/+2
|||||||||||||||||||||| One of our compilers for emscripten coerces all signaling NaNs to quiet ones, so won't do any actual signaling. Anyone relying on them to do so shall be disappointed, so it's better that they know about it at compile-time - or, at least, have the ability to find it out. Put the signaling NaN producers (and remaining (test) code using them) under the control of a feature that's disabled when numeric_limits claims double has no signaling NaN. Assume the bootstrap library doesn't need signaling NaNs. Sadly, until C++20 <bit>, there's no contexpr way to test that alleged signalling and quiet NaNs are actually distinct. Added some auto-tests for signaling NaN, including that it's distinct from quiet NaN. Any platform on which the last fails should disable this feature.
