Try passing -ffp-contract=off. The default was changed to -ffp-contract=on in clang 14. -ffp-contract=on enables the use of FMA instructions for A * B + C if they appear in the same expression. FMA ...

Parabolic partial differential equations (PDEs) are fundamental in modelling a wide range of diffusion processes in physics, finance and engineering. The numerical ...

Abstract: Error model is the basis for accuracy-related computations and analyses for parallel kinematic machines (PKMs). Traditional error modeling methods are ...
