Recommendation: Always use an include guard as shown above to optimize build times and avoid weird build errors. If your compiler supports and optimized #pragma once as an include guard mechanism, you should use that because it is usually more performant and less error prone than using an expli...

The portably library does not support GCC C++ pre 4.7 because the portable library does not work around C++ limitations in stdalign.h and stdint.h before GCC 4.7. This could be fixed but is not a priority. Some previously testet compiler versions may have been retired as the CI environment...
We’ve seen a lot of excitement around C++ modules since we announced support in the Microsoft C++ compiler and Visual Studio. Ever since, the community has been asking us when CMake support was coming. I am happy to announce that Visual Studio 2022 17.2 Preview 2 has experimental support ...
--advice:performance[=all|none] When Trigonometric Math Unit (TMU) support is enabled (--tmu_support) and --fp_mode=strict, advice will be generated if the compiler encounters function calls that could be replaced with TMU hardware instructions under --fp_mode=relaxed. These include floating ...
