types.h@ 94646

Last change on this file since 94646 was 94612, checked in by vboxsync, 3 years ago
VMM/IEM,libs/softfloat,iprt/types.h: The bias adjust value is applied to both unmasked underflows as as well as overflow, reworked the softfloat_roundPackToExtF80 function to do it correct so the new fmul_r80_by_r80 works right. bugref:9898
