Segmented stack mechanism


I am doing research on segmented stack mechanisms, and in addition to academic papers, I am surveying whether segmented stack mechanism is still useful on 64-bit machines. On 64 bit machines, why they don’t just use a big enough stack, for example, 1GB or even larger? Are segmented stacks only useful for 32 bit machines? Are there other reasons for segmented stacks on 64 bit machines?

Any response is appreciated. Thanks, Shucai
