In 64-bit Mode, which segment bases remain architecturally useful for general address calculations?
In 64-bit Mode, which segment bases remain architecturally useful for general address calculations?
a)
CS and DS onlyb)
ES and SS onlyc)
All segment bases work exactly like 16-bit Real Moded)
FS and GSExplanation
In 64-bit Mode, most traditional segmentation is largely disabled for address calculation, while FS and GS retain usable base addresses.Related questions
