cmps and scas instructions accept repeat prefixes F3 and F2. So in order to emulate those prefixed instructions we need to be able to know if prefixes are REP/REPE/REPZ or REPNE/REPNZ. Currently kvm doesn't make this distinction. This patch introduces this distinction. Signed-off-by: Guillaume Thouvenin <guillaume.thouvenin@ext.bull.net> Signed-off-by: Avi Kivity <avi@qumranet.com>
