For eg.. <blockquote> case 0x6: if (cpu->emodel == 0) Identify_Intel_family6pentium(cpu); else Identify_Intel_family6core(cpu); </blockquote> Not pretty, but it works, and doesn't require going back through updating some of the other case:'s. The efamily/emodel checks are done elsewhere instead of munging the traditional values..

For eg..

case 0×6:
if (cpu->emodel == 0)
Identify_Intel_family6pentium(cpu);
else
Identify_Intel_family6core(cpu);

Not pretty, but it works, and doesn’t require going back through updating some of the other case:’s.
