source: vbox/trunk/src/VBox/VMM/include/EMInternal.h@ 41692

Last change on this file since 41692 was 41692, checked in by vboxsync, 12 years ago

DIS: Reducing the DISCPUMODE even more (200 bytes now) and making it have the same layout in all contexts. This is useful since it's used several places in the VM structure. Also a bunch of other cleanups.
