This isn't normally a problem, however, it can lead to problems when switching between CPU models. If switching from a real CPU in the middle of an fprem loop to a simulated CPU, the output of the fprem loop becomes correupted. This changeset changes the fprem implementation to work like the one on real hardware. |
